If from constipation and the consequent accumulation of hardened 

 fgeces in the rectum, the cause must be removed by frequent injections of 

 oil and water, or soap and water, or, if necessary, the removal of the im- 

 pacted dung by the hand, called by some " lack-raking.'''' Always empty

BALANITIS. 



Synonyms. — External clap; Gonorrhoea of the prepuce; Inflamma- 

 tion of the penis and sheath. 



Definition. — Inflammation of the glans penis, generally extending to 

 the sheath. 



Etiology. — This is quite common in stables where proper cleanliness 

 is not observed; the natural secretions collect on the penis and folds of 

 the sheath, dust and dirt get between them, and by-and-by an inflamma- 

 tion is set up by the decomposition and irritation. 



Symptoms. — At first a slight discharge of yellowish pus is observed, 

 having a very foetid odor. The parts swell, and ulcers form inside the 

 sheath. 



Treatment. — If the penis can be drawn out, wash it thoroughly with 

 warm water and soap; if it cannot be got at, syringe out the cavity of the 

 sheath; then apply: 



Chloride of zinc 3ij. 



Water 1 pint. 



Eepeat daily until cured.
