ance for error, we still liave a coiuliliou of things which cannot be 

 exphiintd except by the admission that milk from tubercular cows 

 can and does produce a certain amount of tuberculosis in infants. 

 Prof. Koch also falls into the error of claiming that only those cases 

 which show primary iuttstinal tuberculosis can be attributed to 

 food. Of late years it has been shown beyond doubt that the tonsils 

 may act as the portal of vnivy for tuberculosis. Prof Hueppe, in a 

 recent i^aper incited by Koch's announcement, speaks as follows 

 on this point: "'For this reasoo I have a suspicion that many forms 

 of tuberculosis are at present erroneously attributed to resi)iration, 

 whereas they ought to be attributed to infection from food, es- 

 pecially milk. In a given case it is dililicult to prove this postmor- 

 tem, but it will be suhicicnt to demonstrate that the cases of primary 

 tubeiculosis of the bowels certainly represent only a minimum por- 

 tion of the cases in which infection has been conveyed by way of the 

 mouth wath food*. The iiumber of these cases occurring in children 

 is by oo means so small as Koch alleged. The number of the cases 

 may be fairly reckoned as between 25 and 35 per cent, of all the 

 deaths of children from tuberculosis. All cases of tahes mesenterica 

 belong to this class, and according to Heller, tuberculosis of the 

 mesenteric glands is present in almost a half of all the cases of tuber- 

 culosis affecting- children. To adults, primary tuberculosis of the in- 

 testine is rarer, but it has beesi recognized wath certainty even in 

 them The question, however, is one for public measures to be taken 

 with regard to it. If cattle bacilli establish themselves in even 

 onh' a few cases, they may open the way for a further extension of 

 pathogenic organisms which will now more easily attach themselves 

 to the human subject." 



At the third general meeting, held at Queen's Hall, on Thursday 

 afternoon, July 20, Prof. John McFadyea^i was the principal speaker, 

 his address being an answer to Prof. Koch. It is given here in fall:
