of about I ounce of carbolic acid with 2 ounces of tannin and 6 

 ounces of glycerine in i gallon of warm water. After washing 

 the penis and prepuce thoroughly with soap and water, this solu- 

 tion is applied freely twice daily and a quantity of it is injected 

 up the urethra until it is supposed to reach nearly to the bladder. 



The extent of disease in the urethra has not been investigated. 

 We only know that there is a urethral inflammation and dis- 

 charge and that it is infective. The mere washing of the penis 

 and prepuce cannot, therefore, bring about effective disinfection, 

 but the urethra needs be included. The urethral injection is 

 best made by means of a rubber bulb syringe or a gravity ir- 

 rigating apparatus. The syringe or irrigator nozzle is insert- 

 ed into the urethral opening and retained there while the an- 

 tiseptic solution is forced upward as far as is deemed necessary. 

 Should some of the fluid reach the bladder, it will not prove 

 dangerous but it would be well not to overfill the urethral pass- 

 age at first so that the infective discharges may be largely ex- 

 pelled before taking the risk of forcing them up into the bladder 

 by an excess of the solution. The external ulcers resulting from 

 the pustules may be touched lightly with stick nitrate of silver. 

 The animal needs be kept as free as possible from sexual excite- 

 ment, but should be allowed gentle exercise, along with a re- 

 stricted, laxative diet. The stallion may be returned to the stud 

 as soon as all evidences of disease have disappeared but, for a 

 time, it might be advisable to continue the disinfection, especiallj' 

 after each service. 



The handling of the mare should be along the same general 

 line and should be persevered in until all symptoms have disap- 

 peared. As a general rule, she will recover sufficiently during 

 the interval between two estrual periods that she may again be 

 bred at the first return of estrum since the contraction of the 

 disease, should she not prove to be in foal. 



The differentiation of this affection from Dourine is highly 

 important, but has already been discussed on page 83. 



There is little need for police control of this disease, since its 

 sytaptoms are so prominent that laymen promptly note it and 

 voluntarily withdraw the affected animal from breeding until re- 

 covery has occurred. Should there at any time be a negligent 

 tendency shown, the affected animals should be promptly quar- 

 antined until all danger has passed.
