the bacilli could easily pass to the placenta, thence to the 

 liver of the foetus and so into the general circulation. He 

 stated that he had on several occasions seen tuberculosis of 

 the placenta and often of the uterus. These were dangerous 

 infective cases, the bacilli escaping in the uterine discharges. 



As was to be expected, the museum contained a complete 

 collection of specimens of tuberculosis of nearly every organ 

 in the bodies of different animals-Seattle, horses, dogs, pigs 

 and sheep. The udder specimens interested us especially. 



He believes that the tubercle bacillus dies if simply raised 

 to 85 C., and that it is not necessary to keep it for any 

 length of time at that temperature. 



Having submitted a copy of our " Farmers' Bulletin " on 

 tuberculosis, for his consideration, we met again in the even- 

 ing to discuss it. 



He took exception to the statement that calves reared from 

 tuberculous cows are predisposed to tubercle. " If this," he 

 said, " were true, it would upset my whole work." He was 

 quite emphatic on this and said that unless exposed to con- 

 tagion after birth they were no more predisposed to tubercle 

 than to broken legs or other accidents. Referring to testing 

 he believes that for practical purposes and saving of time, 

 consequently expense, one or at most two temperatures taken 

 previous to injection would be sufficient. 



He thinks it is too much to claim that in ninety-eight cases 

 out of 100 the showing of the tuberculin test is absolutely 

 reliable. He puts the maximum at eighty-seven per cent. 



He does not agree with Nocard who claims that tuberculin 

 does not lie, and that in every case when tuberculin indicates 

 undoubtedly tuberculosis it can be found if looked for with 

 sufficient care. 



With these exceptions he endorses our bulletin. 



TUBERCULIN. 



All the tuberculin used in Denmark is prepared by Professor 

 Bang and his assistant in his laboratory, to which we paid a 

 visit. The culture room is separate from the laboratory
