become weaker and more debilitated, finally dying in a comatose condi- 

 tion. In no instance has the natural recovery of an animal after once 

 the symptoms of taliosis were noticed heen observed or heard of. 



The yomiger goats seem to be the most susceptible to the disease, 

 although the old animals are liy no means immune. 



Pathological Anatomy. As already indicated, the general appearance 

 of the carcase simulates that produced by a wasting disease. The visible 

 mucous membranes are pale and anaanic, while the fleece, which appears 

 somewhat dry and lustreless, furnishes a shroud for the extremely 

 emaciated condition, that becomes plainly perceptible on skinning. The 

 same anssmic condition of the subcutaneous and muscular tissues is 

 observed ou eviscerating the carcases. The lungs in most cases are the 

 seat of a peculiar diversified inflammation, never of a remarkahle extent. 

 The external appearance of these organs is at times mottled, caused by 

 a few congested areas, several patches of an iron-grey colour similar to 

 areas of pneumonia during the process of absorption, and normal tissue. 

 On section through the reddened patches, a frothy mucus may exude 

 from the bronchioles, and in one case numerous punctiform haemorrhages 

 were observed on the sides of the incision. This tissue, wlnle not so 

 buoyant as a normal portion would he, nevertheless floats when plaeed 

 in water. 



The heart in all cases is pale and dull, its tissue soft and flabby,, 

 while inflamed areas, more or less penetrating, are present at times oni 

 the epicardium about the auricular appendages, and at other times oa 

 the endocardium, especially that lining the ventricles. These hemor- 

 rhagic patches consist of either pure extravasated blood or blood mixBdl 

 with serum, which gives tliem a more diffuse appearance and a gela- 

 tinous consistence. The pericardium is slightly thickened, and usually 

 contains a small increase of fluid tinged with blood. The liver usually 

 appears normal, although the gall bladder is frequently distended with 

 pale-yellow watery bile. The kidneys are anaemic and softened. The 

 cortex appears slightly thicker and paler than normal, and contrasts 

 strongly with the darker pyramids. The capsule strips oS' easily from 

 the parenchyma of the organ. In one instance several pale areas simu- 

 lating anfemic infarcts were o])served under the capsule extending into 

 the cortex, which probably resulted from the compression of the capillaries 

 by the swollen parencljymatous cells. The presence of albumin in the 

 urine was detected by the nitric-acid test. The spleen appears atrophied 

 and indurated, and on section the fibrous tissue far exceeds the splenic 

 pulp. Attachments by fibrous adhesions may fix the sjjleen to the 

 diaphragm or the neighbouring organs. The intestines may contain 

 normal faecal matter or semi-fluid faces of a disagreeable odour. The 

 sui'face of the mucous membrane is at times covered with a slimy
