Boyce. (Results given by Annett, Lancet, 1900, p. 160.) 
He examined the market milk of Liverpool, England ; his results 
are given in the following table: 
Year 1898 : Per cent tuberculous. 
Town milk (75 specimens) 6.6 
Country milk (28 specimens) 17.8 
Year 1899 : 
Town milk .(75 specimens) 6.6 
Country milk (63 specimens) 17.4 
The superiority of the town milk is attributed to the inspections 
conducted in town.

Repeatedly examined the milk of eight Berlin dairies. This milk 
was designed especially for the use of children, was not sterilized, and 
sold for 35 to 60 pfennig per liter. In three of these dairies the cows 
were rigidly tuberculin tested. No tubercle bacilli were ever found 
in this milk. In the other five the cows were subjected to clinical 
oversight by veterinarians, but the tuberculin test was employed only 
now and then upon suspicious animals. In three of these five dairies 
the milk was found to contain tubercle bacilli. The percentage of 
specimens containing tubercle bacilli is not stated.

Klein examined 100 samples of milk from various country farms in 
the vicinity of London. The samples were placed in conical glasses 
and allowed to sediment. Smears were made from the sediment and 
examined microscopically for tubercle bacilli; guinea pigs were also 
inoculated subcutaneously and intraperitoneally with the sediment. 
Klein’s results were: Eight guinea pigs died acutely, 7 showed 
positive tuberculosis, while 42 gave negative results at autopsy. The 
remainder showed staphylococcic and Streptococcic infection.

nimmt, mit besonderen Untersuchungen ueber die Milch des Paduaner 
Marktes. Arch. f. Hyg., 1900, v. 41. 
This author examined the market milk of Padua. Forty-six 
samples were centrifugalized and the cream and sediment injected 
intraperitoneally into 103 guinea pigs. Nine died within forty-eight 
hours, and none of the remainder when they were killed showed tuber- 
culosis. Tonzig is of the opinion that the danger of infection with 
tubercle bacilli in mixed milk is only slight.
