OUR DOMESTICATED ANIMALS. 39 



brethren in India, I regret to notice how slow they 

 have hitherto been to acknowledge their indebtedness 

 to experimental helminthology. But for our laborious 

 and successful efforts in this department of scientific 

 work at home, they could not have known of the inter- 

 mutual relations of the measle and tapeworm of beef. 

 No doubt they might have guessed as much from the 

 experiments successfully initiated by Kiichenmeister on 

 condemned criminals with the pork measle; but, as 

 regards the beef tapeworm, even Leuckart himself 

 doubted, in the first instance, that which his own 

 experiments and my verifications subsequently proved to 

 be true. 



Many other experiments are necessary to complete our 

 knowledge of the genesis of the different species of cestode 

 parasites; and we shall continue to make them from time 

 to time, although our labours may not happen to receive 

 their due recognition at the hands of those we have 

 principally benefited. The exhilarating effect produced 

 on the mind of the investigator by the sudden in-rush of 

 a, newly-aquired scientific truth is in itself a reward quite 

 apart from the larger consideration of contributing 

 to the welfare of mankind. 



If I offer these remarks in a tone of gentle reproach, 

 it is in order that I may do the more justice to diligent 

 co-workers in India, who, profiting by our researches, 

 have not only contributed a series of valuable facts 

 as the result of mere observation, but have likewise 

 recently entered upon the more difficult and instructive 

 path of experimental inquiry. 



In this connection I allude more especially to the 

 experiments conducted by Dr. Oliver, of the Koyal 

 Artillery, stationed at Jullunder. By the courageous
