go 6 Mr. Home’s Account of the 
appears soon to form an attachment to the person who 
feeds it. 
A specimen of this animal has since been sent to me in 
spirits ; the viscera had been removed, but the male organs of 
generation, and the structure of the limbs, were the same as 
in the wombat. There was no subdivision of vessels in the 
groin as in the tardigrade animals. 
The external form of the wombat has been described by 
M.Geoffroy in the second volume of the Annales du Museum 
National de France; and several parts of its internal structure 
have been taken notice of by M. Cuvier in his Lei^ons d’Ana- 
tomie comparee. It only remains to mention such peculiarities 
as have either been slightly touched upon, or entirely passed 
over in the different accounts. Among these is the mechanism 
of the bones and muscles of the hind legs, which differs in 
many respects from that of all other animals, except the 
koala. The following account of it is drawn up at my desire, 
by Mr. Brodie, from an accurate examination of the parts. 
“ There is no patella ; but the tendon of the extensor muscles 
of the leg, where that bone is usually situated, is much thick- 
ened. 
“ The fibula is proportionably larger than in most animals. 
At the upper extremity it is broad, and has two distinct arti- 
culating surfaces : the anterior of which is articulated to the 
tibia, and the posterior to a small bone of a pyramidal shape, 
which is connected to the tendon of the external head of the 
gastro-cnemius muscle like a sesamoid bone. The lower ex- 
tremity of the fibula is large, and forms about half of the 
articulating surface for receiving the tarsus at the ankle. An 
inter-articular cartilage is here interposed between the tibia
