and until disinfection has been enforced to the satisfaction of the 
said health officer. After these measures have been taken, the 
sale of milk may be resumed. This is a mere outline of the 
regulations, but when their salient points are considered the 
plan is very practical if it is a little cumbrous. In order to get 
into more immediate touch with the producers whose milk may 
be contaminated in this way, it would be necessary to have all 
milk producers licensed, and a provision made which would 
force them under severe penalties to report all suspicious cases of 
illness among the operatives of the establishment to a properly 
constituted medical inspector.. Even this plan has its serious 
disadvantages, for if the disease so reported should be an infec¬ 
tious one it would inflict a great though temporary loss upon 
the producer, and it does not take a very deep insight into hu¬ 
man nature to see that the producers, or many of them at least, 
would resort to every subterfuge in order to avoid making such 
a report. 
The alternate plan to the above one is, to have these licensed 
dairies visited every week by an appointed health officer, whose 
duty it would be to report and to act upon such cases. It might 
be possible to enforce both of these plans of inspection at one 
and the same time. 
The above remarks, let me remind you, refer to inspection as 
applied to secondary afltection. We will now return to the con¬ 
sideration of inspection as applied \.o primary infection of milk. 
If you will pardon the repetition, I will restate that primary in¬ 
fection means the transmission to man through the vehicle of 
milk of diseases which are common both to man and the lower 
animals. Of all the primary infections beyond comparison 
tuberculosis transcends the others in importance because it is so 
common and so deadly. It is estimated that about 14 per cent, 
of our population die of this disease. study of the results of 
tubercular tests will show that about the same proportion of 
cows are similarly affected. The saddest part of this record of 
fatality is the fact that out of the 14 per cent, of human deaths 
from this cause a relatively large proportion of them are infants.
