In the waxwork collection (eighth room) many of the anatomical reproductions come from the château of the Duke of Orleans--known during the Revolution as Philippe Égalité--at Chantilly. Others, executed with rare perfection, are from Florence, always celebrated for this kind of work. At the entrance to the ninth room are two figures, considered marvels of ingenuity and of science in the last century, but now looked upon as, for purposes of study, next to useless: an “arterial” man and a “venous” man. Very curious, too, are the children’s heads, in which skilful injections, even into the most delicate veins, have given to the complexion the appearance of life. They have been furnished, according to the taste of the period, with enamel eyes, and to render them presentable to the public, each little head is enveloped in a lace cap. In the eleventh room will be found the collection of Dr. Gall, including the very heads on whose developments he formed his theory of localised faculties and cerebral bumps. It may here be observed that the followers of Gall have rendered his system questionable by giving to it in detail a value which he attached to it only in a general way. The collection contains, moreover, the bust of Dr. Gall himself, a cast of his head taken after death, and his very cranium, on which may be sought the special bump of phrenologism. Here, too, may be seen the masks of Voltaire, Casimir Périer, François Arago, and Jean Jacques Rousseau. This last was taken by the sculptor Houdon, at Les Charmettes, July 4, 1778--the day after Rousseau’s death. A bust of Cuvier is to be seen on the ground floor, to which a staircase leads directly from the Gall collection. It is the work of David d’Angers, and stands in front of five skeletons of elephants, which seem to form for the great comparative anatomist a guard of honour.
