mon in this division, and this organ is often soft and fatty. A 
tree-kangaroo (Dendrolagus inustus) had tubercles of the liver. The 
most remarkable death among these pouched animals was that of a 
great kangaroo (Macropus major), namely, from bleeding of the 
bowels ; the blood appeared to ooze from a large extent of surface 
of the mucous lining of the alimentary canal. This membrane was 
very dark and ecchymosed. The cause of this was not apparent, as 
the animal was in excellent condition. In two Tasmanian Wolves 
(Thylacini) the deposit of fat was very abundant, and in one which 
died in hot weather, and the body of which was exhumed, the oily 
fat appeared to permeate almost every tissue. 
Rodentia.—About thirty individuals of this order have been dis- 
sected, and tuberculous deposits in the liver and spleen were often 
present ; several died from inflammation of the lungs. A Cana- 
dian porcupine (Hrethizon dorsatum) died of distended stomach, 
having gorged itself with potatoes, after a sea-voyage. A beaver 
( Castor fiber) presented a large amount of tubercular disease of the 
liver and spleen, although in tolerable condition ; whilst the body of 
the large squirrel (Sciurus maximus), in excellent condition, revealed 
no satisfactory cause of death. The two Capybaras afforded the 
most remarkable deviations from normal structure ; one, as recorded 
in the ‘ Proceedings of the Pathological Society,’ 1854, p. 347, had 
scirrhus of the kidney; the last that died had the liver so softened 
that the bile-ducts, arteries, and veins could be readily pulled from 
the substance of the liver ; both suprarenal capsules, too, were en- 
larged and diseased,—a very rare occurrence in the lower animals. 
Edentata.—The examination of the misnamed toothless animals 
has been very limited, three armadillos and one large ant-eater (Myr- 
mecophaga jubata) forming the whole. The armadillos appeared to 
die from derangement of the assimilative organs ; in one the liver was 
soft and fatty, but in none of the above was there any active disease. 
Pachydermata.— Although the animals in this section are but few 
in number, the morbid appearances were of especial interest. In the 
female Asiatic elephant which I examined the condition of the blood 
was very remarkable ; it was generally tough, and could readily be 
pulled out of the vessels; one portion from the posterior cava and 
iliac veins measured 4 feet in length. The animal, apparently in 
good health, was frightened during a thunder-storm, had profuse 
watery diarrhoea, and died the next day. As these animals are not 
often inspected, I may mention that I examined the viscera of another 
Asiatic elephant that died in Yorkshire from inflammation of the 
lungs after exposure to severe cold. Of three tapirs (7'. americanus), 
two died of peritonitis ; in one this was occasioned by a small oblong 
smooth perforation of the stomach from simple ulceration, as exhi- 
bited in the drawing; in the second the cause of the peritonitis ap- 
peared to be doubtful ; the third had brain symptoms from diseased 
kidneys. The death of two peccaries (Dicotyles torquatus) was oc- 
casioned by inflamed lungs. An Indian sow (Sus indicus) died of 
abscess of the brain. . A zebra, when apparently in good health and 
in excellent condition, broke its neck by striking its head against the
