CROUPAL VAGINITIS. 545 



more active, but require more careful handling. Hydroxyl diluted 

 with from 3 to 5 parts of water is also of great efficacy. Strong 

 solutions should never be used, because they cause irritation and ex- 

 pulsive efforts. 



All these injections may be made without difficulty by passing a 

 simple perforated drainage tube to the end of the vagina, and con- 

 necting it with a syringe, or, better, with a small cistern hung from 

 the wall, which allows the required pressure to be obtained. 



"\^ hen there are deep and severe wounds, the parts should be washed 

 out once or twice daily and the vagina should be packed with surgical 

 wool and iodoform gauze. The septic liquids are absorbed by the 

 dressing, which acts continuously. This dressing is renewed until re- 

 covery takes place. 



CONTAGIOUS VAGINITIS. 



During the past few years certain observers have described a disease 

 which has been termed "contagious vaginitis," in consequence of the 

 facility with which it is transmitted. 



This vaginitis may be transmitted by copulation, the bulls then 

 serving as propagators of the disease. The bulls themselves are usually 

 affected with balanitis. 



The causative agent of the disease is unknown. 



This contagious vaginitis is characterised by all the symptoms of 

 acute vaginitis, and it is only from the fact of its appearing in all the 

 animals served by one bull that its contagious character is established. 

 A short time after service the vulva appears swollen and extremely 

 sensitive ; at the same time general disturbance appears, viz., diminu- 

 tion of appetite and of milk secretion, slackening of rumination, etc. 



Vaginal exploration, which is somewhat difficult, reveals a papulo- 

 vesicular eruption, accompanied by a muco-purulent discharge. 



This vaginitis is easy to diagnose. It may disappear spontaneously, 

 and the treatment differs in no respect from that of ordinary acute 

 vaginitis. 



CEOUPAL VAGINITIS. 



Croupal vaginitis is a form of acute vaginitis, from which it is dis- 

 tinguished by the formation of false membranes resembling those of 

 diphtheria over the whole of the vaginal mucous membrane. 



It was described by Baumeister. Moussu has only seen one case, 

 and that at a period which rendered recovery out of the question. 



Symptoms. The external symptoms are those of acute vaginitis, 

 with greyish, foetid, purulent or sanguinolent discharge. On examina- 

 tion, ae mucous membrane is found to be covered with yellowish, 

 crev'ish false membranes, and with vegetations of a greyish, dirty, 



DC.
