316 A TREATISE ON HORSE-BREEDING. 



lutely secluded. It may be a consequence of idleness, to- 

 gether with a want of sexual intercourse, and especially 

 when the animal is kept on very rich and stimulating food; 

 otherwise, a constitutional predisposition to excessive virility 

 may exist. The evil may be remedied by seclusion, more 

 frequent sexual intercourse, woi'k, less nutritious food, the 

 administration of occasional laxatives; also by the use of 

 bromide of potassium in two-drachm doses; or camphor with 

 nitrate of potassium, respectively one and two-drachm doses. 

 Castration as a last resort. 



NON-EMISSION OF SEMEN, OR "PROUDNESS," SO-CALLED. 



The question is frequently asked: "What causes a stallion 

 to dismount proud?" or "What can be done for a 'proud' 

 stallion?" This condition is a variety of sterility in which 

 sexual intercourse is not finished with an ejaculation of semen, 

 either because that fluid does not enter the urethra, or be- 

 cause its forcible expulsion is prevented by some obstacle in 

 the course of the urethra. Non-emission may be congenital 

 or acquired, and permanent or temporary. It may be, and 

 probably most frequently is, the result of either masturbation 

 or over-taxation of the sexual organs. Dr. Howe says oa 

 this subject: "The power of erection remains intact, but the 

 patient exerts himself in vain to produce an orgasm. This 

 condition may continue a few weeks, disappear and then re- 

 turn. It is by no means a permanent condition, but it may 

 lead to permanent sterility and impotence. Some writers 

 say that it is due to spasm of the orifices of the ejaculatory 

 duct, which prevents the passage of seminal fluid into the 

 urethra; others, that it is due to a lack of secretion in the 

 various glands. This latter view, however, is not tenable, 

 because such patients are subject to nocturnal pollutions as a 

 result of lascivious dreams. It is more than probable that 

 there is a temporary paralysis of sansation existing in the 

 prostatic portion of the urethra, in the ducts, and perhaps 

 in the vesicles. This lack of sensation prevents the reflex 

 muscular action necessary for the propulsion of the semen." 



This latter view coincides with my opinion, stated above, 

 as to the most frequent causes of this condition in stallions,
