APPENDIX VI. 



The Second Interim Report of the Royal Commission on 

 Human and Animal Tuberculosis was issued in January, 1907. 

 It presents the conclusions of the commission after thorough 

 and extensive investigations covering more than five years. 



The report is signed by Sir Michael Foster, Prof. G. Sims 

 Woodhead, Prof. Sidney Martin, Sir John McFadyean and 

 Prof. Rubert Boyce. 



The following is an extract: 



CONCLUSION 



11 We may briefly sum up the bearings of the results at 

 which we have already arrived as follows : 



" There can be no doubt but that in a certain number of 

 cases the tuberculosis occurring in the human subject, es- 

 pecially in children, is the direct result of the introduction into 

 the human body of the bacillus of bovine tuberculosis; and 

 there also can be no doubt that in the majority at least of 

 these cases the bacillus is introduced through cows' milk. 

 Cows' milk containing bovine tubercle bacilli is clearly a cause 

 of tuberculosis and of fatal tuberculosis in man* 



li Of the sixty cases of human tuberculosis investigated by 

 us, fourteen of the viruses belonged to Group I, that is to say 

 contained the bovine bacillus. If, instead of taking all these 

 sixty cases, we confine ourselves to cases of tuberculosis in 

 which the bacilli were apparently introduced into the body by 

 way of the alimentary canal, the proportion of Group I becomes 

 very much larger. Of the total sixty cases investigated by us, 

 twenty-eight possessed clinical histories indicating that in them 

 the bacillus was introduced through the alimentary canal. Of 

 these, thirteen belong to Group I. Of the nine cases in which 

 cervical glands were studied by us three, and of the nineteen
