OUR DOMESTICATED ANIMALS. ' 49 



will candidly admit that in this important matter I have 

 hitherto advanced no proposition which cannot be 

 substantiated by known and easily recognisable data. 

 In its own pages for Feb. 25, 1865, my experimental 

 successes were first announced; whilst experiences 

 similar to those there recorded have since received 

 abundant confirmation. 



As I cannot enter into further particulars respecting 

 the sewage aspects of this subject, I must refer those 

 who are interested in them to the last of my Cantor 

 Lectures, delivered before the Society of Arts, May 15, 

 1871. This Lecture was expressly devoted to "the 

 general question of the parasitism of ruminants in 

 relation to sewage and public health;" and in it I have 

 endeavoured to refute all the more important arguments 

 adduced by my opponents. 



The astonishing facts brought forward by Dr. Kaschin, 

 a medical officer attached to the Russian army, are too 

 significant to be allowed to pass unnoticed. From him, 

 through Leuckart, we long ago learnt that the Burates, 

 or Cossacks, of the Baikal region are nearly all infested 

 with tapeworms. They feed upon the flesh of calves, 

 sheep, camels, and horses. They neither dress the 

 meat properly, nor cook it completely. Fat, liver and 

 kidneys are eaten quite raw ; diseased animals being as 

 much relished as half-rotten carcases. These people are, 

 moreover, extremely voracious ; any two of them being 

 capable of demolishing a one-year-lamb at a single meal. 



With such data before us, no one need wonder at the 

 further assurances of Dr. Kaschin to the effect that in a 

 hospital containing five hundred persons, who were being 

 treated for other diseases, there was not a single patient 

 who was not, at one and the same time, infested with
