232 Diseases of the Genital Orga?is 



The well-filled crop and well-developed egg in the oviduct 

 indicated sudden death. The liver presented several lacera- 

 tions covered with blood, and on its caudal side between the 

 intestinal loops an extensive hematom. The connective tis- 

 sue of the groin was infiltrated. The egg tube contained a 

 hard-shelled egg. The cloaca was gaping and dilated to 

 2V2 cm., much larger than normal. Four days later another 

 dead hen was brought for autopsy by another neighbor. The 

 cadaver presented the same lesions, with the addition that 

 the left tibia was broken and, yet more important, two 

 mammalian spermatoza were found in the cloaca. The liver 

 rupture was apparently due to the violent holding of the 

 hen to prevent her escape. Later, in another locality, an 

 owner lost a number of hens, one at a time, at intervals of 

 one to a few days, and finally a sick bird was brought Guille- 

 beau for observation. Eight days later it was necessary to 

 kill her. The autopsy revealed bloody serum and fibrin 

 clots in the body cavity, the liver greatly enlarged and con- 

 taining large cavities filled with blood serum, the intestines 

 adherent. Apparently the wounds were essentially like the 

 foregoing, but not so severe as to cause immediate death. 



The incentives to such an offense lie in a great sexual 

 craving with a low moral sense, while in other respects the 

 person may be normal or even bright. 



The subject is without material veterinary interest be- 

 yond diagnosis, and through this means to enable the owner 

 to secure police protection. 



Sadism, or that type of sexual perversion which leads per- 

 sons to mutilate the genital and neighboring organs, is of 

 far more frequent interest to veterinarians and, owing to 

 the endless variety of mutilations, offers extraordinary diffi- 

 culties in diagnosis. Many of the mutilations prove fatal, 

 and the pervert is so persistent in the perpetration of the 

 offense that delay in diagnosis may cause great economic 

 loss, as well as serious embarrassment to the veterinarian. 

 Errors in diagnosis have certainly injected into our litera- 

 ture some very mysterious and illogical accounts of coital 

 injuries. Quite naturally a sex pervert is equally or more 

 liable to commit the offense upon an animal in estrum. at
