INFLUENCE OF DISEASE UPON MILK 77 
the products (meat and milk) of tuberculous animals. 
The investigations were therefore largely directed along 
these lines. The present views of those who have studied 
the subject are fairly represented by the conclusions 
reached by the British commission and published in 1911 
after a careful and thorough inquiry extending over ten 
years. These conclusions are as follows: 
“There can be no doubt that a considerable propor- 
tion of the tuberculosis affecting children is of bovine 
origin, more particularly that which affects primarily the 
abdominal organs and the cervical glands. ‘And, fur- 
ther, there can be no doubt that primary abdominal tuber- 
culosis as well as tuberculosis of the cervical glands is 
commonly due to ingestion of tuberculous infective 
material.” One hundred and eight cases of human tuber- 
culosis other than lupus were examined by the Commis- 
sion and bacilli of the bovine type were found in twenty- 
four, or 22 per cent. The latter included sixteen cases 
of primary abdominal tuberculosis, three of tuberculosis 
of the cervical lymph glands, two of pulmonary tubercu- 
losis, two of tuberculosis of the bronchial lymph glands 
and one of joint tuberculosis. Bacilli of the bovine type 
were found in nearly half of the fatal cases of primary 
abdominal tuberculosis. 
The German commission made a study of fifty-six 
different cultures obtained from cases of tuberculosis in 
man and found six, or more than 10 per cent., to be of 
the bovine type. 
Park and Krumwiede® determined the type of bacilli 
present in 487 cases of tuberculosis in man and collected 
from the literature the records of 1033 cases in which the
