The disease may last eight days before ending in recovery. 

 When death takes place it is about the fourth or sixth day. 



Lesions. The false membranes are found on the ileum and 

 colon, in thin films or in thick masses, or tubular casts. In ex- 

 treme cases the membrane has covered an extent of 24 feet in 

 length, and if recent it is soft and friable. If older it may be 

 firm, consistent and yellow or stained by the blood or ingesta. 

 As in solipeds it shows a reticulated network and a fine granular 

 structure, and is composed mainly of inspissated mucus with al- 

 buminoids and fibrine. The exudate covers a surface of extreme 

 redness, with points of darker blood-staining and even abrasion 

 or ulceration. The surrounding mucosa is also congested, the 

 villi hypertrophied, the mucous follicles swollen. 



Treatment. In the early stages a laxative of soda sulphate is 

 of especial value in depleting from the inflamed mucosa, liquefy- 

 ing the secretions and dissolving and loosening the false mem- 

 branes. Epsom salts, cream of tartar, Rochelle salts, calomel, 

 and pilocarpin are more or less valuable substitutes. Iodide of 

 potassium is most valuable in dissolving the exudate and acting 

 as a microbicide (dose 3-4 drs.). 



Other alkaline salts may be substituted or as antiseptics the 

 sulphites, hyposulphites, or sulphides of potash or soda. Borax, 

 bismuth, naphthol and creolin have also been recommended. 

 Enemata of warm water are desirable. 



In very adynamic conditions, muriatic acid (^ dr. doses) may 

 be given with vegetable bitters and the same may be allowed 

 during convalescence.
