18 THE INTEKNAL PAEASITES OE 



The late Mr. Youatt, when commenting on a remark- 

 able case of death from canine parasitism (where poisoning 

 had been suspected), very truthfully observed : " The 

 history of the entozoa has been unpardonably neglected 

 by veterinary practitioners."" Since his time, however, 

 the labours of Professors Simonds, Dick, Brown, and 

 others, have thrown much light upon the pathological 

 aspects of entozoal research ; but all is not yet known 

 that might be, in connection with these amphistomes. 

 Not alone in cattle have these parasites been found. 

 They occur also in the sheep, goat, red deer, roe, fallow, 

 elk, and certain species of antelope. Moreover, two 

 other amphistomes, alleged to be distinct, have been 

 detected in the well-known Indian variety of the ox 

 termed the zebu. One of these (Amphistoma crumeniferum 

 is obtained from the paunch ; the other Amjohistoma ex- 

 jplanatv/m) from the gall bladder and hepatic duct. 

 Although in possession of specimens from the zebu, I 

 have not yet been able to verify the published statements 

 respecting the distinctive characters given in Creplin's 

 original description of the worm from the paunch; but 

 this is of little practical consequence. 



In conclusion, I may mention that a number of care- 

 fully mounted, amphistomes may be seen in the entozoo- 

 logical series of the Hunterian Museum, Lincoln's-inn. 

 The examples were originally obtained by Mr. Clift from 

 the paunch of a reindeer.
