of the quarters swell, he loses power more or less complete; the urine becomes 
coffee or porter colored, containing albumen, haemoglobin, and sometimes blood 
cells. 
Dr. Wyat Johnston presented a specimen sent by Dr. J. M. Parker, of ac- 
cinomykosis on the left face and superior maxilla of a cow, the peculiar rounded 
yellow spots caused by the actinomyces. He pointed out the difference between 
this disease and osteo sarcoma, it being caused by these vegetable spores. That 
the parasitic fungus often found its way into the bone by the puncturing of the 
gum by straw or coarse grass stalks. Being most frequent in animals used for 
food for people, it being communicable to man as well as to other cattle, it is a 
matter of importance for sanitarians. He also exhibited specimens of pleuro¬ 
pneumonia, and specimens of the lungs of Canadian animals suspected of pleuro¬ 
pneumonia by inspectors in Great Britain. He explained the differences, which, 
however, in the hardened specimen are not well marked. Undoubtedly there 
exist forms of pneumonia in cattle, resulting in pathological changes simulating 
pleuro-pneumonia so closely as to make it difficult to differentiate between them, 
and until a micro-organism shall be discovered in pleuro-pneumonia we must rest 
our opinion principally on the history leading or not to contact of living diseased 
with living healthy cattle. Dr. McEacliran explained that in the fresh section of 
so-called “Canadian Lung ” the alveoli and interlobular spaces were filled by a 
white waxy exudate, while in pleuro-pneumonia the exudate in these spaces is 
invariably fluid, and the general condition of the lung dropsical, and in the former 
there is usually an absence of the necrotic centres and various pathological evi¬ 
dences of progressive inflammation, seen in contagious pleuro-pneumonia. 
This closed the last active meeting for the session, which has been an un¬ 
usually successful one for this Association.
