Other members of the strongylus group have been frequently 

 found, particularly in the bronchi of members of the deer family. 

 In one case, that of a mule deer, it is possible that this condition 

 produced fatal broncho-pneumonia. 



Cysticerci have been frequently found in various animals and 

 invading nearly every viscus, but apparently they have not caused 

 death in any case. 



A rather extensive study has been made of an instance of the 

 Mischerschen schleuche, which was found in the myocardium of 

 an elk, where it clearly caused death — a rather unusual occurrence 

 with this ordinarily innocent parasite. A communication con- 

 cerning this study was presented before the New York Pathologi- 

 cal Society. Pfeiffer concludes from his experiments with this 

 sarcosporidien that animals will not become infected from eating 

 muscle containing it, and Ostertag recommends that in the in- 

 spection of meat for human food, that flesh containing this para- 

 site need not be rejected unless the muscle-tissue itself be secon- 

 darily diseased. This is a matter of great importance, since the 

 parasite is very frequent in the muscles of sheep, deer, and other 

 animals used for food. The parasite has been found in the hu- 

 man a few times (Kartulis, Barbaran, and St. Remey, Rosen- 

 berg, and Lindermann). It is probably more frequent in the 

 human than these few examples indicate. In my opinion, meat 

 which contains them should never be used either for animal or 

 human food unless the meat be thoroughly cooked. The work of 

 Theobald Smith, in the November (1901) number of the Jour- 

 nal of Experimental Medicine, bears me out in insisting on this 

 precaution, for he has systematically infected mice by feeding 

 them muscle containing this parasite. 



Other forms of parasitic diseases have also occurred at the 

 Park among the birds and carnivora, but these cases have not 

 come under my personal observation. 



SUGGESTIONS. 



I have very little to offer at this time in the way of recommenda- 

 tions, for the reason that in the past such few suggestions as have 

 been proposed by me have been so quickly and efficiently put into 

 practice. 



I am particularly desirous of seeing the Park animals put un- 

 der as nearly perfect hygienic conditions as exist in human hos-
