of hides are liable to the attacks of insects, unless preserved 
in some way. We would, therefore, recommend the use of 
the arsenical soap as in other skins. 
ANT-EATERS. 
The great Ant-Eater (Myrmecophega jubata), has a long 
prehensile tail, with long flowing hairs. The tail must be 
supported by a much longer tail-bearer than that of other quad- 
rupeds generally. The tongue is very long and protractile, and 
ought to be drawn out of the mouth as if in the act of 
catching Ants. 
THE DUCK-BILLED PLATYPUS ( Ornithorinchus rufus.) 
In stuffing this animal, attention must be paid to showing 
as much as possible its cheek pouches, a characteristic of the 
genus. 
ORDER VIIL—PACHYDERMATA. 
The animals of this Order are mostly of gigantic size, and 
have very thick skins. At the head of this Order is 
THE ELEPHANT. 
Various methods have been devised for the mounting and 
stuffing of Elephants. The best plan is that which was adopt- | 
ed, with the elegant specimen now in the Jardin du Roi 
at Paris. 
The dead Elephant being extended on the ground, the di- 
mensions were all taken, and correctly noted at the time. M. 
Lassaigne, cabinet-maker to the establishment, invented a 
large rule for that purpose, which was somewhat like a shoe- 
maker's size-stick. The different curves of the back, belly, 
neck, &c., were taken by bars of lead of three quarters of an 
inch in thickness. This metal is much better adapted than 
any other for that and similar purposes, as it has no elasticity, 
it retains any shape into which it is put. 
M. Demoulins made a drawing of the animal from these
