under, we have 280 cases, 215 of which were human and 65 

 bovine, coming' very close to the figures taken from cHnical work 

 in England, from which we get the best information on this sub- 

 ject, namely, that from about 23 to 25 per cent of the fatal cases 

 of tuberculosis in children are due to bovine infection. And these 

 figures do not include the numerous non-fatal cases which pro- 

 duce only more or less permanent and more or less severe de- 

 formities of the skeleton — hipjoint disease, psoas abscesses, en- 

 larged glands of the neck, etc. \Mien we come to take these into 

 account it seems fairly evident that 30 per cent of the cases of 

 tuberculous children are due to bovine infection." Another emi- 

 nent authority. Dr. Stiles of Edinburgh, has come to the con- 

 clusion from clinical evidence that most of these cases of bone 

 and joint tuberculosis were of bovine origin. Being called into 

 consultation once he made a diagnosis of bovine tuberculosis in a 

 child who was too far gone to be helped and died within a few 

 days. The father said the infection could not be bovine as he 

 kept his own cow, and she had been tuberculin tested. The cow 

 was killed and found to be simply riddled with tuberculosis — a 

 far advanced case, such as frequently fail to react to the test. 

 The father was so impressed that he then and there gave a large 

 sum of money for an investigation, the results of wdiich have just 

 been published, and some of which are interesting enough to be 

 quoted here: "Seventy cases were examined, these being chil- 

 dren most of which have not died. Forty-one of these showed 

 the bovine bacillus, and 23 human ; three showed both bovine and 

 human bacilli. Sixty-seven of these cases vv^ere children twelve 

 years or under, and three adults between 24 and 30 years. Forty- 

 seven were children five years old or under and of these 2>2 were 

 infected with the bovine bacillus and 15 with the human, a per- 

 centage of 68." Dr. Stiles goes on to say: "When we come to 

 examine the family history of these cows, we find some very 

 impressive facts. In 21 cases there was a family history of tuber- 

 culosis. Of these, 15 gave human cultures and 6 bovine. That is 

 71 per cent showed human infection, whereas, in the 52 cases 

 where there was no family history of tuberculosis, 9 prove to 

 be human and 43 bovine : in other words 83 per cent of these 

 cases were due to bovine infection. The final conclusions to this 

 very valuable contribution to our knowledge of the importance 

 of the bovine tuberculous infection to children, are to 

 the eft'ect that "nobody can deny the great danger to human 

 health from bovine tuberculosis." "It is a black spot on the repu- 

 tation of our civilization at the present time, to permit this pre- 

 ventable disease to continue to reap a harvest of over one million 

 deaths every single year. In the United States alone over 200.000 

 of our fellow citizeris every year g-o down to their graves from a 

 preventable disease." 



I have taken the liberty to quote these figures at length for the 

 reason that the local sanitary authorities, as well as the Anti-
