Egidius Romanus on the formation of the human body in the mother's womb 862 .
863 I believe to be the signature of Charles d'Amboise the Governor of Milan. If this explanation is the right one, it can be easily explained by the contents of Nos. 1350 and 1529. The note, line 1, was perhaps added later by another hand; and Leonardo himself wrote afterwards on the same sheet some geometrical explanations. I must also point out that the statement that this sheet belongs to the year 1509 has absolutely no foundation in fact.

Pour conclure je crois qu'il n'est pas prouve que Leonard de Vinci n'ait pas fait un voyage de quelques mois en France sous Louis XII, entre le printemps de 1509 et l'automne de 1510."--I must confess that I myself have not succeeded in deciphering completely this French writing of which two words remain to me doubtful. But so much seems to be quite evident that this is not an address of a letter at all, but a certificate or note. Amboise[l. 6
