Rayer mentions two nails sent to him by Bricheteau, physician of the Hopital Necker, belonging to an old woman who had lived in the Salpetriere.
They were very thick and spirally twisted, like the horns of a ram.
Saviard informs us that he saw a patient at the Hotel Dieu who had a horn like that of a ram, instead of a nail, on each great toe, the extremities of which were turned to the metatarsus and overlapped the whole of the other toes of each foot.

The skeleton of Simore, preserved in Paris, is remarkable for the ankylosis of all the articulations and the considerable size of all the nails.

The fingers and toes, spread out and ankylosed, ended in nails of great length and nearly of equal thickness.

A woman by the name of Melin, living in the last century in Paris, was surnamed "the woman with nails;" according to the description given by Saillant in 1776 she presented another and not less curious instance of the excessive growth of the nails.
Musaeus gives an account of the nails of a girl of twenty, which grew to such a size that some of those of the fingers were five inches in length.

They were composed of several layers, whitish interiorly, reddish-gray on the exterior, and full of black points.
