culosis to the State authorities, whether that be the State Board 
of Health, the Department of Agriculture, Bureau of Animal 
Industry, Board of Tuberculous Commissions, or a State Vet¬ 
erinarian, for appraisal, so that owners might be indemni¬ 
fied up to a certain value, for example, as fixed by the present 
law. 
ft remains with this body, our State Veterinary Medical Asso¬ 
ciation, the Dairyman’s Association of all the counties of Greater 
New York and our city Department of Health, to use every means 
in their power, individually and collectively, to see to it that 
some proper measure is prepared, or law passed, by our next 
Legislature to rid our herds of tuberculous cows on an equal 
basis with our rural dairymen in competition with our local 
dairies, and to the advantage of all our milk, so that we may 
get a healthy food. 
At some future time, gentlemen, I will have something to 
say on “ Hygienic Marketing of Milk.” 
CALCULI. 
By B. F. Kaupp, D. V. S., Inspector B. A. I., Kansas City, Mo. 
A Paper read before the Missouri Valley Veterinary Medical Association, Oct. 5, 1898. 
I choose for my subject this evening “ Calculi,” for the 
reason that we see so many upon post-mortem and find little 
literature on the subject, and I hope this short discourse will 
bring out a lengthy discussion. 
Calculi are concretions in any part of the animal body, most 
frequently occurring in organs acting as reservoirs and in the 
excretory canals, and occurring in animals of all ages. They are 
met with in the biliary ducts, gall bladder, pancreas, salivary 
ducts, urinary pa.ssages (usually the kidney, bladder and pre¬ 
puce), and in the digestive tract. They may be owing to 
deposition of substances from fluid passing along the duct or a 
product of nutritive irritation. 
The information I have collected from the bladder men at 
the large abattoirs, corroborates the information gained from the
