44 Professor Sims Woodhead, Human and Bovine Tuberculosis. 



So far as mode of growth and lesions produced in the tissues, 

 size of organism, tuberculin reaction and all known characters 

 give us any lead we are I think bound to maintain that the 

 differences between bacilli obtained from tuberculous lesions in 

 the human being and those obtained from similar lesions in 

 cattle, are not specific, and that for this reason, the tubercle 

 bacillus, from whatever source it may be derived, constitutes a 

 distinct, and even grave, danger to any human or brute subject 

 to which it may gain access and I for one should be unwilling to 

 accept any responsibility for suggesting the relaxation of the 

 laws dealing with any thing in which this highly infective agent 

 is concerned. Indeed I would go further than this as I con- 

 sider it essential that it is our duty to do all that we possibly 

 can to strengthen the hands of Medical Officers of Health and 

 their Inspectors in the difficult task with which they are now 

 confronted.
