OUR DOMESTICATED ANIMALS. 45 



cysts exhibit " a highly characteristic appearance. " The 

 slice itself has been cut and unfolded so as to show 

 four measles (a), which, lying pretty nearly on the same 

 level, have been severally divided by the knife into 

 more or less equal moieties. 



Some of my specimens of measly veal and beef show 

 twice or thrice as many cysts within a similar area ; but 

 I have purposely preferred Dr. Lewis's representation, 

 as giving a fair and in nowise exaggerated view of the 

 natural possibilities of the case under ordinary circum- 

 stances. To the butcher who supplied the sirloin Dr. 

 Lewis dispatched a messenger, hoping to obtain some 

 more choice specimens of the meat for the purposes of 

 experiment, but he was disappointed by the reply that 

 the beef in question was " all sold." 



Striking as is the evidence thus adduced by Dr. Lewis 

 and others respecting the prevalence of measles in India, 

 I have seen no statements which are so remarkable as 

 those communicated to me by Dr. Joseph Fleming, of the 

 Army Medical Staff. None of our experimental animals, 

 though fed with scores of ripe proglottides, yielded such 

 an abundance of cysticerci as he appears to have encoun- 

 tered in the Punjab cattle. In reply to my inquiries, 

 he has deliberately stated, and I doubt not with perfect 

 truth, that " in one pound weight of the psoas muscles 

 he counted 300 living cysticerci." Clearly, facts of 

 this order are of the highest practical value. 



The degree of infection of measly meat can rarely be 

 ascertained by applications to fleshers, since they have 

 many motives for concealing their knowledge. Thus, 

 at home, I have at times found difficulty in procuring 

 samples of measly pork, although this form of parasitism 

 is well known to butchers; and similar difficulties will
