are laid prematurely without albumen or without shell, yet with 

 much eifort and suffering. Or the bowels become irritable and 

 a profuse diarrhoea sets in, hastening the exhaustion of the 

 patient. 



Treatment should be applied early. A cooling diet of vege- 

 tables or slops, the careful removal of all irritating contents 

 from the oviduct, and its frequent injection with bland oils medi- 

 cated with mild anti-septics (boric or salicylic acid, or potassium 

 permanganate) will usually serve a good purpose.

Cause : chronic metritis, tumors, microbian infection. Symptoms : ill- 

 health, low condition, vulvar swelling or discharge, swelling and fluctuation 

 of womb. Rectal exploration. Treatment : evacuate liquid, disinfect

As a rule these conditions belong to obstetrics and would not 

 come under the scope of this volume, but when in chronic cases,

 work. 



The cause is usually a chronic metritis, originating it may be at 

 the time of a now distant parturition, or associated with tumors

 follow upon parturition and abortion streptococcus is usuall}- 

 present, in the more chronic forms the staphylococcus or other

The symptoms are those of general ill-health, low condition, 

 pallor of the visible nmcosse, .sometimes swelling of the vulva

 behind and dividing in front into two horns. 



Treatment consi.sts in the evacuation of the liquid through a 

 catheter or cannula introduced through the os, or through the 

 vaginal wall immediately above, followed by a systematic disin-
