IMMUNITY. 381 



only 30 cases 2 deaths, or 6.6 per cent., while 

 Glaser's statement regarding 3285 cases, from 

 1869-1877, without specific treatment, showed 

 a mortality of 7.5 per cent., with a minimum 

 of 5 per cent, and a maximum of 9.6 per cent. ; 

 in the general hospital at Hamburg between 

 1882-1891, the fatality was 2298 among 25,824 

 patients, or 8.9 per cent, with a minimum of 

 6 per cent. (1887) and a maximum of 19 per 

 cent. (1882). How far larger numbers would 

 affect for the worse the results of Frankel 

 and Rumpf we can not conjecture since the 

 above data were communicated before the ter- 

 mination of all the cases. The only conclusion 

 that can be fairly drawn therefore, is that it is 

 possible to inject both isopathic and antagonis- 

 tic substances into typhoid patients. Whether 

 it is possible to bring about a cure by this 

 method is still wholly uncertain ; in any case 

 the same result was achieved, probably even 

 a better result, without use of any of these 

 remedial substances and therefore without risk 

 of doing injury. 



The proteids bring about their effect (as 

 shown on p. 180) in a general way, by excit- 

 ing inflammation in the tissues invaded by the 

 microparasites. H. Buchner has proved also 

 by researches made upon the action of arsenic 

 that the reactions of the human body taking
