BULLETIN 66. 
man, and because cattle products, as milk and butter, are 
used in the raw state they are a constant menace to the 
public health. It is important then that the greatest care 
and sanitary precautions should be used in handling cattle 
and their products. Outside of the danger to man there is 
the item of financial loss from the presence and spread of 
disease among our stock. These are sufficient reasons for 
every cattle owner applying every test and attention which 
will insure keeping only healthy stock. Dr. Bang, the great 
Danish authority, has succeeded in having laws passed 
which makes sanitary precautions compulsory in Scandina¬ 
via, and already enough has been done in Europe to show 
that tuberculosis may be materially decreased by proper 
sanitary control of tuberculous subjects among both animals 
and man. In Denmark national laws make it compulsory 
to heat all milk to 185 degrees F. before it is sold, or before 
butter is made from it. 
In Germany tuberculous persons are required to take 
the sanitary treatment prescribed and they find that tuber¬ 
culosis is decreasing under these laws. Many of our states 
have legislative regulations for stamping out tuberculosis 
among cattle, and some of them are extreme in requiring 
the slaughter of all reacting animals. If human and bovine 
tuberculosis prove to be the same disease, it would seem 
that this method would be the surest and quickest way of 
removing the greatest of all dangers to human life, but be¬ 
cause of the uncertainly, we are probably not ready at the 
present time to adopt such drastic and expensive measures. 
However, enough is known at the present time so no one is 
excusable for using milk or butter from cows which have 
not been given a bill of health and demonstrated free from 
tubercle, and no stockman is excusable for harboring and 
breeding the disease in his herd. 
RESULTS OF THE TESTS. 
Three tests have been made of the cattle on the College 
farm, by Dr. Geo. H. Glover, veterinarian. The first on 
December 8, 1900, was of all the cows being milked in the 
dairy, consisting of seven Jerseys and one Shorthorn and 
also one Shorthorn which had lost her calf and had not 
been doing well for some time. Table I gives the result of 
this test, showing the normal temperatures determined be¬ 
fore inoculation and the rise in temperature after injection.
