called milk inspection in the large cities, but the adulteration 
of milk with water and the skimming of cream cannot compare 
with tuberculosis in milk. As tuberculosis is difficult to

from each cow be microscopically examined, and then the 
cow examined by a qualified person. By taking these pre¬ 
cautions I think we could, in a measure, improve the health 
of the people, as well as that of our domestic animals.

to rise, eating and drinking, with a small amount of abdomi¬ 
nal pain ; inquired about faeces and urine; was informed that 
urine was passed regular, but faeces were very hard and 
passed with difficulty. On examining head, I found on the 
lower jaw a little anterior to first molar, and on the external 
face on each bone, a circumscribed swelling about half the size
