I learn that the plural of bodach glas was in Welsh bodachod gIension, a term which Elis o'r Nant remembers his mother applying to a kind of fairies dressed in blue and fond of leading people astray. She used to relate how a haymaking party once passed a summer's night at the cowhouse (beudy) of Bryn Bygelyfd (also Bryn Mygeldd), and how they saw in the dead of night a host of these dwarfs (corynnod) in blue dancing and capering about the place. The beudy in question is not very far from Dolwyddelan, on the way to Capel Curig. A different picture of the bodach is given in Jenkins' Bedd Gelert, p. 82; and lastly one may contrast the Highland Bodach Glas, not to mention still another kind, namely the one in Scott's Waverley.
 To Sarn yr Afanc add Llyn yr Afanc, near Llanddinam (Beauties of Wales, N. Wales, p. 841), and Bedd yr Afanc, 'the Afanc's Grave,'the name of some sort of a tumulus, I am told, on a knoll near the Pembrokeshire stream of the Nevern. Mr. J. Thomas, of Bancau Bryn Berian close by, has communicated to me certain echoes of a story how an afanc was caught in a pool near the bridge of Bryn Berian, and how it was taken up to be interred in what is now regarded as its grave. A complete list of the afanc place-names in the Principality might possibly prove instructive. As to the word afanc, what seems to have happened is this: (1) from meaning simply a dwarf it came to be associated with water dwarfs; (2) the meaning being forgotten, the word was applied to any water monster; and (3) where afanc occurs in place-names the Hu story has been introduced to explain it, whether it fitted or not. This I should fancy to be the case with the Bryn Berian barrow, and it would be satisfactory to know whether it contains the remains of an ordinary dwarf. Peredur's lake afanc may have been a dwarf; but whether that was so or not, it is remarkable that the weapon which the afanc handled was a ffechwaew or flake-spear, that is, a missile tipped with stone.
 With the role of the girl in the afanc story compare that of Tegau, wife of Caradog Freichfras, on whom a serpent fastens and can only be allured away to seize on one of Tegau's breasts, of which she loses the nipple when the beast is cut off. The defect being replaced with gold, she is ever after known as Tegau Eur-fron, or 'Tegau of the golden Breast' That is a version inferred of a story which is discussed by M. Gaston Paris in an article, on Caradoc et le Serpent, elicited by a paper published (in the November number of Modern Language Notes for 1898) by Miss C A Harper, of Bryn Mawr College, U.S.: see the Romania, xxviii. 214-31. One of Miss Harper's parallels, mentioned by M. Paris at p. 220, comes from Campbell: it is concerning a prince who receives from his stepmother a magic shirt which converts itself into a serpent coiled round his neck, and of which he is rid by the help of a woman acting in much the same way as Tegau. We have an echo of this in the pedigrees in the Jesus College MS. 2o: see the Cymmrodor, viii. 88, where one reads of G6ga6n keneu menrud a vu neidyr vl6ydyn am y von6gyl, 'Gwgon the whelp of Menrud (?) who was a year with a snake round his neck'--his pedigree is also given. In M. Paris' suggested reconstruction of the story from the different versions, he represents the maiden who is to induce the serpent to leave the man on whom it has fastened, as standing in a vessel filled with milk, while the man stands in a vessel filled with vinegar. The heroine exposes herself to the reptile, which relinquishes his present victim to seize on one of the woman's breasts. Now the appropriateness of the milk is explained by the belief that snakes are inordinately fond of milk, and that belief has, I presume, a foundation in fact: at any rate I am reminded of its introduction into the plot of more than one English story, such as Stanley Weyman's book From the Memoirs of a Minister of France (London, 1893), p. 445, and A. Conan Doyle's Adventures of Sherlock Holmes (London, 1893), pp- 199-209. In Wales, however, it is to a woman's milk that one's interest attaches: I submit two references which will explain what I mean. The first of them is to Owen's Welsh Folk-Lore, p. 349, where he says that 'traditions of flying snakes were once common in all parts of Wales,' and adds as follows:--' The traditional origin of these imaginary creatures was that they were snakes, which by having drunk the milk of a woman, and by having eaten of bread consecrated for the Holy Communion, became transformed into winged serpents or dragons! The other is to the Brython for 1861, p. 190, where one reads in Welsh to the following effect -- 'If a snake chances to have an opportunity to drink of a woman's milk it is certain to become a gwiber. When a woman happens to be far from her child, and her breasts are full and beginning to give her pain, she sometimes milks them on the ground in order to ease them. To this the peasantry in parts of Cardiganshire have a strong objection, lest a snake should come there and drink the milk, and so become a gwiber.' The word gwiber is used in the Welsh Bible for a viper, but the editor of the Brython explains, that in our folklore it means a huge kind of snake or dragon that has grown wings and has its body cased in hard scales: for a noted instance in point he refers the reader to the first number of the Brython, p. 3. It is believed still all over Wales that snakes may, under favourable circumstances, develop wings: in fact, an Anglesey man strongly wished, to my knowledge, to offer to the recent Welsh Land Commission, as evidence of the wild and neglected state of a certain farm, that the gorse had grown so high and the snakes so thriven in it that he had actually seen one of the latter flying right across a wide road which separated two such gorse forests as be described: surprised and hurt to find that this was not accepted, he inferred that the Commissioners knew next to nothing about their business.
 With ' the spell of security' by catching hold of grass may perhaps be compared a habit which boys in Cardiganshire have of suddenly picking up a blade of grass when they want a truce or stoppage in a sort of game of tig or touchwood. The grass gives the one who avails himself of it immunity for a time from attack or pursuit, so as to allow him to begin the game again just where it was left off.
 Bodermud would probably be more correctly written Bodermyd,and analysed possibly into Bod-Dermyd, involving the name which appears in Irish as Diarmait and Dermot.
. Since this was printed I have been assured by Mr. Thomas Prichard of Llwydiarth Esgob, in Anglesey, that the dolur byr is more commonly called clwy' byr, and that it is the disease known in English as black quarter.'
. I am assured on the part of several literary natives of Glamorgan that they do not know dar for daear, 'ground, earth.' Such negative evidence, though proving the literary form daear to prevail now, is not to be opposed to the positive statement, sent by Mr. Hughes to me, as to the persistence in his neighbourhood of dar and cldr (for claear, 'lukewarm '), to which one may add, as unlikely to be challenged by anybody, the case of harn for haearn, ' iron.' The intermediate forms have to be represented as daer, claer, and haern, which explain exactly the gaem of the Book of St. Chad, for which modern literary Welsh has gaeaf, 'winter': see the preface to the Book of Llan Ddv, p. xIv.
 It ought to have been pointed out that the fairies, whose food and drink it is death to share, represent the dead.
. For Conla read Comnla or Condla: the later form is Colla. The Condla in question is called Condla Ruad in the story, but the heading to it has Ectra Condla Chaim, I the Adventure of C. the Dear One.'
 I am now inclined to think that butch was produced out of the northern pronunciation of witch by regarding its w as a mutation consonant and replacing it, as in some other instances, by b as the radical.
. With the Manx use of rowan on May-day compare a passage to the following effect concerning Wales--I translate it from the faulty Welsh in which it is quoted by one of the competitors for the folklore prize at the Liverpool Eisteddfod, 1900: he gave no indication. of its provenance:--Another bad papistic habit which prevails among some Welsh people is that of placing some of the wood of the rowan tree (coed cerddin or criafol) in their corn lands (llafyrieu) and their fields on May-eve (Nos Glamau) with the idea that such a custom brings a blessing on their fields, a proceeding which would better become atheists and pagans than Christians.
. In the comparison with the brownie the fairy nurse in the Pennant Valley has been overlooked.
 With the story of Ffynnon Gywer and the other fairy wells, also with the wells which have been more especially called sacred in this volume, compare the following paragraph from Martin's Description of the Western Islands of Scotland (London, 1703), pp. 229-30: it is concerning Gigay, now more commonly written Gigha, the name of an island near the west coast of Kintyre:--'There is a well in the north end of this isle called Toubir-more, i. e. a great well, because of its effects, for which it is famous among the islanders; who together with the inhabitants use it as a Catholicon for diseases. It's covered with stone and clay, because the natives fancy that the stream that flows from it might overflow the isle; and it is always opened by a Dirock, i. c. an inmate, else they think it would not exert its vertues. They ascribe one very extraordinary effect to it, and 'tis this; that when any foreign boats are wind-bound here (which often happens) the master of the boat ordinarily gives the native that lets the water run a piece of money, and they say that immediately afterwards the wind changes in favour of those that are thus detain'd by contrary winds. Every stranger that goes to drink of the water of this well, is accustomed to leave on its stone cover a piece of money, a needle, pin, or one of the prettiest vadeated stones they can find.' Last September I visited Gigha and saw a well there which is supposed to be the one to which Martin refers. It is very insignificant and known now by a name pronounced Tobar a viac, possibly for an older Mo-Bheac: in Scotch Gaelic Beac, written Beathag, is equated with the name Sophia. The only tradition now current about the well is that emptying it used to prove the means of raising a wind or even of producing great storms, and this appears to have been told Pennant: see his Tour in Scotland and Voyage to the Hebrides, MDCCLXXII (Chester, 1774), p. 226:-- I Visit the few wonders of the isle: the first is a little well of a most miraculous quality, for in old times, if ever the chieftain lay here wind-bound, he had nothing more to do than cause the well to be cleared, and instantly a favorable gale arose. But miracles are now ceased.'
. A similar rhyme is current in the neighbourhood of Dolgelley, as Miss Lucy Griffith informs me, as follows:--
Dolgolle dol a gollir,
Daear a'i llwnc, dw'r 'n 'i lle.
Dolgeltey, a dale to be lost;
Earth will swallow it, and water take its place.
. With regard to wells killing women visiting them, I may mention a story, told me the other day by Professor Mahafry after a friend whose name he gave, concerning the inhabitants of one of the small islands on the coast of Mayo--I understood him to say off the Mullet. It was this: all the men and boys, having gone fishing, were prevented by rough weather from returning as soon as they intended, and the women left alone suffered greatly from want of water, as not one of them would venture to go to the well. By-and-by, however, one of them gave birth to a boy, whereupon another of them carried the baby to the well, and ventured to draw water.
. As to Clychau Abordyfi I am now convinced that the chwch and saith are entirely due to the published versions, the editors of which seem to have agreed that they will have as much as possible for their money, so to say. I find that Mrs. Rhys learnt in her childhood to end the words with Pump, and that she cannot now be brought to sing the melody in any other way: I have similar testimony from a musical lady from the neighbourhood of Wrexham; and, doubtless, more evidence of the same sort could be got.
. For Lywelyn ab Gruffydd read Llywelyn ab Iorwerth.
 Some additional light on the doggerel dialogue will be found thrown by the following story, which I find cited in Welsh by one of the Liverpool Eisteddfod competitors:--There is in the parish of Yspytty Ifan, in Carnarvonshire, a farm called Trwyn Swch, where eighty years ago lived a man and his wife, who were both young, and had twins born to them. Now the mother went one day to milk, leaving the twins alone in the cradle-the husband was not at home-and who should enter the house but one of the Tylwyth Teg! He took the twins away and left two of his own breed in the cradle in their stead. Thereupon the mother returned home and saw what had come to pass; she then in her excitement snatched the Tyluyth Teg twins and took them to the bridge that crosses the huge gorge of the river Conwy not very far from the house, and she cast them into the whirlpool below. By this time the Tylwyth Teg had come on the spot, some trying to save the children, and some making for the woman. 'Seize the old hag!' (Crap ar yr hen wrach.!) said one of the chiefs of the Tylwyth Teg. 'Too late!' cried the woman on the edge of the bank; and many of them ran after her to the house. As they ran three or four of them lost their pipes in the field. They are pipes ingeniously made of the blue stone (carreg las) of the gully. They measure three or four inches long, and from time to time several of them have been found near the cave of Trwyn Swch.- This is the first indication which I have discovered, that the fairies are addicted to smoking.
. A Rkiw Gyferthwch (printed Rywgyverthwch) occurs in the Record of Carnanvon, p. 200; but it seems to have been in Merionethshire, and far enough from Arfon.
 In the article already cited from the Romania, M. Paris finds Twrch Trwyth in the boar Tortain of a French romance: see xxviii 217, where he mentions a legend concerning the strange pedigree of that beast. The subject requires to be further studied.
 A less probable explanation of Latio would be to suppose orti understood. This has been suggested to me by Mr. Nicholson's treatment of the Lanaelhaiarn inscription as Ali ortus Elmetiaco hic iacet, where I should regard Ah as standing for an earlier nominative Alec-z, and intended as the Celtic equivalent for Cephas or Peter: Ali would be the word which is in Med. Irish ail, genitive ailech, 'a rock or stone.'
 We have the Maethwy of Gilvaethwy possibly still further reduced to Aethwy in Porth Aethwy, 'the Village of Menai Bridge,' in spite of its occurring in the Record of Carnanvn P. 77, as Potthaytho.
 To the reference to the Cymmrodor, ix- 170, as to Beli being calledson of Anna,add the Welsh Elucidarium, p. 27, with its belim vab anna, and The Cambro-Btitish Saints, p. 82, where we have Anna . . . genuit Beli..
. Two answers to the query as to the Llech Las are now to be found in the Scottish Antiquary, xv. 41-3.
. Caer Gai is called also Caer Gynyr, after Cai's father Cynyr, to wit in a poem by William Lleyn, who died in 1587. This I owe to Professor J. Morris Jones, who has copied it from a collection of that poet's works in the possession of Myrdin Fard, fo. 119.
. Here it would, perhaps, not be irrelevant to mention Caer Dwrgynt, given s v. Dwr in Morris' Celtic Remains, as a name of Caergybi, or Holyhead. His authority is given in parenthesis thus: (Th. Williams, Catal.). I should be disposed to think the name based on some such an earlier form as Kair D6bgint, 'the Fortress of the Danes,' who were called in old Welsh Dub-gint (Annales Cambriae A. D. 866, in the Cymmrodor, ix. x 65), that is to say 'Gentes Nigrae or Black Pagans,' and more simply Gint or Gynt, 'Gentes or Heathens.'
 The word banna6c, whence the later bannog, seems to be the origin of the name bonoec given to the famous horn in the Lai du Corn, from which M. Paris in his Romania article, xxviii. 229, cites Cest cor qui bonoec a non, 'this horn which is called bonoec.' The Welsh name would have to be Corn (yr) ych banna6c, 'the horn of (the) bannog ox,' with or without the article.
 One of the Liverpool Eistedfod competitors cites W. O. Pughe to the following effect in Welsh: Llyn dau Ychain, 'the Lake of Two Oxen,' is on Hiraethog Mountain; and near it is the footmark of one of them in a stone or rock (carreg), where lae rested when seeking his partner, as the local legend has it. Another cites a still wilder story, to the effect that there was once a wonderful cow called Y Fuwch Fraith, 'the Particoloured Cow.' 'To that cow there came a witch to get milk, just after the cow had supplied the whole neighbourhood. So the witch could not get any milk, and to avenge her disappointment she made the cow mad. The result was that the cow ran wild over the mountains, inflicting immense harm on the country; but at last she was killed by Hu near Hiraethog, in the county of Denbigh.'
. With trwtan, Trwlyn- Tratyn, and Ttit-a-trot should doubtless be compared the English use of trot as applied contemptuously to a woman, as when Grumio, in Shakespeare's Taming of the Shrew, Act i, sc. 2, speaks of 1 an old trot with ne'er a tooth in her head': the word was similarly used by Thomas Heywood and others.
. I find that Professor Zimmer is of opinion--in fact he is quite positive-- that tyngu and tynghed are in no way related: see the Gottingische gelehrte Anzeign for 1900 (No. 5), pp. 371-2.
. I am tempted to rank with the man-eating fairies the Atecotti, who are known to have been cannibals, and whose name seems to mean the ancient race. Should this prove tenable, one would have to admit that the little people, or at any rate peoples with an admixture of the blood of that race, could be trained to fight. Further, one would probably have to class with them also such non-cannibal tribes as those of the Fir Bolg and the Galiflin of Irish story. Information about both will be found in my Hibbert Lectures, in reading which, however, the mythological speculations should be brushed aside. Lastly, I anticipate that most of the peoples figuring in the oldest class of Irish story will prove to have belonged either (i) to the dwarf race, or (2) to the Picts; and that careful reading will multiply the means of distinguishing between them. Looking comprehensively at the question of the early races of the British Isles, the reader should weigh again the concluding words of Professor Haddon's theory.
