tubercular deposits. The left humero-radial or elbow joint 
is considerably enlarged and had given rise to lameness during 
3 past few months. The knee joint of the same leg was first 
solved, but now appeared healthy. The synovial membrane 
d extremities of the humerus and radius were in a diseased 
ndition, hut presented no calcareous deposits or appearances of 
eumatoid arthritis. The prepectoral and brachial lymphatic 
ands were found to contain much cheesy and calcareous 
I itter. 
Cows Edith , Crummie, Mildred , Blanche , and others showed 
tensive granulations on the costal and pulmonary pleurae, which 
some instances firmly united the lungs to the ribs. 
Helen Hart , in addition to similar lesions of the thoracic 
^ans, revealed well developed tubercles in the udder. Some of 
sse had broken down, and their contents were discharged into 
e milk sinuses, and tainted the milk—a fact that had been 
served by those in charge for some days. 
It does not appear necessary for me to detail the lesions found 
individual cases beyond this, except to remark that other 
gans of the body were frequently involved—liver, intestines, 
3 . The calves presented mostly diseased conditions of lymphatic 
mds and intestines; diarrhoea and other digestive disorders 
ing here most marked. 
Out of the forty-seven (47) head destroyed, all (four or five 
Ives were not examined, but were killed because of being the 
.’spring of diseased dams, and having occupied the infected 
rn,) presented symptoms which, as you probably are aware, 
)re accurately interpreted in every instance, even where but 
ry small and deep-seated portions of lung tissue were involved. 
The uniformity of these symptoms and pathological lesions 
ist prove to all thinking minds (whether little or nothing is 
own of the appearances of the disease in question) that there 
isted in each individual member of the herd one and the same 
3ease. 
That this disease is both hereditary and contagious seems also 
tent from the facts that calves scarcely one month old were 
ainly affected, and that those animals recently bought and
