472 ANNUAL REPORT OF THE Off. Doc. 



Copenhagen; others less fortunate, have succumbed to the progres- 

 sive evolnrion of the infection, sucli as our brethren, Moses, of Wei- 

 mar, and Thomas Wallev, of the Rojal Veterinary College of Edin- 

 burgh. 



Furthermore, there exist numerous instances of infection by the 

 use of milk coming from cows with tuberculous mammitis. The best 

 known and most authoritative, concerns one of the daughters of Prof. 

 Gosse, of Geneva. It has almost the value of an experiment. 



Finally the work of the great English hygienist, Thorue-Thorne 

 proves as well as evidence the reality and gravity of the danger. 

 During fifty years the mortality from tuberculosis in England has 

 diminished forty-five per cent.; during this same time, abdominal tu- 

 berculosis of infants has increased twenty-seven per cent. How 

 can we explain these figures so different? It is only for the last 

 fifty years that you have done much in this country towards the 

 cleansing of the house, the work-shop, public places, lessening in this 

 way the chances of infectioo by means of the respiratory tract, 

 much the most common mode for adults; but you have done nothing 

 against the dangers of infection by the digestive tract, which is the 

 most frequent method for children artificially nourished. 



Thorne-Thorne does not hesitate to attribute the increase of tu- 

 berculosis in young children to the absence of all regulations in re- 

 gard to the dairy and of all measures prohibiting the use of milk 

 coming from cows with tuberculosis of the udder. All those who 

 study this question of milk agree with the opinion jof Thorne-Thorne. 

 It is for these reasons that I will continue to teach to-day as yester- 

 day: 'Mothers of families; do not give milk to your babies unless the 

 milk has been boiled.' " 



Professor Bang, of Copenhagen, was then called upon by the 

 chairman, and said that he thought Professor Koch had gone a little 

 too far in saying that there was no necessity for taking measures 

 against bovine tuberculosis. He had proved that there was very lit- 

 tle danger in inoculating cattle from man, but the inoculation of man 

 from cattle was a different matter, and they should be cautious in 

 accepting his conclusions about it. 



Professor Sims Woodhead (Cambridge), was also called upon. He 

 said that Professor Koch's paper was a masterly exposition of his 

 subject, but the very weight of his word going out to the world 

 made it desirable that, if there was anything to be said on the other 

 side, it should be known too. He was himself convinced that bovine 

 tuberculosis did play some part in the extension of the disease 

 and he adduced several reasons for his opinion. Among them 

 lie referred to an experiment of Professor Crookshank's, and said 

 th;it one snrh ymsitive result outweighed a large number of nega- 

 tive ones. Professor Korh had told them that a commission had
