cially will this prove true at the dairy farm, whose product is 
placed on the market for exchange. 
Harold Ernst, on the subject of infectiousness of milk, arrives 
at these conclusions : ist. While the transmission of tuberculosis 
by milk is probably not the most important means by which the 
disease is propagated, it is something to be guarded against most 
carefully. 2d. The possibility of milk from tuberculous udders 
containing the infectious element is undeniable. 3d. With the 
evidence here presented, it is equally undeniable that milk from 
diseased cows with no appreciable lesion of the udder may, and 
not unfrequently does, contain the bacillus of the disease. Mr. 
President, are we imposing too much on your patience, and this 
assembly, by stating that it is our belief, that we as veterinarians 
and sanitarians fall short in our professional duties unless we use 
all reasonable means to impress upon dairymen who place their 
product upon the market, the necessity of as perfect sanitary 
conditions as is possible to maintain ; and especially whenever it 
comes to our notice that milk is offered for sale from cows in an 
unhealthy condition of body, to use our best endeavor to have 
them removed from the herd, or report the case to the health 
officer. Neither should milk be sold from dairies in which cer¬ 
tain diseases incident to the human family are prevalent, and as¬ 
sociated with the dairy. Diseases which should bar the dairy 
product from sale are typhoid fever, diphtheria, pulmonary 
phthisis, croup, scarlet fever, common measles, German measles, 
small pox, erysipelas and syphilis. There is room for much re¬ 
form in the dairy sections of our State; and who among the sci¬ 
entists is better qualified to perform so important a public func¬ 
tion than the veterinarian. I will not go into the details of the 
dairy, which are many and complex, aside from what has 
already been said as to cleanliness, the method to be pursued 
and the material used is quite essential. 
A thorough sweeping down of the walls and ceilings of the 
stables twice a year, spring and fall, then applying a rich coat 
of whitewash and carbolic, which is both a disinfectant and par¬ 
asiticide, the maintaining of water-tight floors and gutters, so
