50 THE INTERNAL PAEASITES OP 



tapeworm. Fortunately these people suffer less than 

 we ourselves would do were we placed in like circum- 

 stances and played the part of " host " to the same 

 extent; but this consideration in no wise lessens the 

 value of the entozoological evidences thus afforded. 

 It may be added also that, as the Burates seldom eat 

 pork/ it is nearly certain that most of their cestode 

 guests belong to the species of tapeworm which is 

 derived from eating veal and beef. 



The measles or cysticerci have a preference for the 

 external muscles of animals, selecting principally those 

 of the shoulder and haunch. They are comparatively 

 rare in the deep-seated muscles, although I have found 

 many of them in the diaphragm. An exception must also 

 be made in favour of certain other muscles which help 

 to form the walls of the abdominal cavity. Beef measles 

 develop pretty freely in the loose cellular and fatty 

 tissues ; at least I have removed many from such 

 situations. However, in contradiction to my personal 

 experiences, Dr. Alexander Neill, in the Madras Beport 

 already quoted (p. 107), states that "the larvae of Taenia 

 mediocanellata will only come to maturity in the mucous 

 membrane, [and] not in the cellular tissue of horned 

 cattle/'' This assertion is not borne out by the facts 

 noticed in my experimental calf, in which animal the 

 connective tissues were invaded, especially in the regions 

 of the so-called facia lumbaris as well as in that of 

 the linea semicircularis. Measles are also liable to take 

 up their residence in the heart ; but, probably on 

 account of the density of the muscular substance of that 

 organ, they do not acquire so large a size as elsewhere, 

 and, according to my own examinations, very few of 

 them become perfectly formed. As seen in the specimen
