SEXUAL APPARATUS. 193 



Cows show symptoms of great restlessness, are very 

 excitable, bellow frequently, attack strangers, etc. Milk se- 

 cretion is reduced, the milk has a bad taste and sometimes 

 curdles when boiled. 



In horses and bulls satyriasis manifests itself by 

 restlessness and excitable, sometimes vicious, actions. 



In many cases the cause of these conditions cannot be as- 

 certained ; in cows tuberculosis of the ovaries, in horses cryp- 

 torchism, is often the cause. 



A. Female Sexual Organs. 



II. The vulva. In bitches we observe swelling of the vulva' 

 and a bloody mucous discharge at the^oestral period. In cows a 

 tough glassy mucus is discharged just before parturition. This 

 mucus comes from the neck of the uterus which it served to close. 



A slight swelling of the vulva occurs in vesicular eruption 

 of this region ; small vesicles the size of a millet seed, and 

 swelling may also occur in the adjacent skin in this condition. 

 In puerperal septicemia the vulva swells conspicuouslv. 



In torsion of the uterus the vulva is retracted and 

 drawn into folds; however, exploration per vagina 

 is necessary to definitely determine this condition. 



Discharge from the inferior commis- 

 sure of the V u 1 V a and soiling of the surroimding skin 

 and tail are observed in: 



a. Catarrh of the vagina and uterus. In chronic catarrh 

 (fluor albus) the discharge is of a thick shmy character 

 and glassy ; in acute catarrh the discharge is of a thin slimy 

 character and discolored. 



b. Retention of the afterbirth; an ill-smelling, discolored 

 fluid mixed with fragments of the fetal membranes is dis- 

 charged. 



c. Vesicular eruption ; the discharge is slight, slimy or 

 purulent, sometimes mixed with blood. 



d. Tuberculosis ; slight, chronic, muco-purulent discharge 

 containing tubercle bacilli.
