_Treatment._ Antiseptics given by the mouth have proved of very little avail having as a rule lost their power through dilution in the contents of the stomachs. They may still be given to keep in check the propagation of the coccidia in the fourth stomach. Silver nitrate, iron sulphate, lead acetate, tannic acid, oak bark, carbolic acid, cresol, lysol, salicylic acid, hydrochloric acid, sulphuric acid, hyposulphite of soda have been used in this way. The same agents may be used with better effect as enemata being forced as far as is consistent with safety and frequently repeated. Quinia and iodide of potassium may also be given as parasiticides. Mucilaginous gruels and decoctions should be given at first, followed by mashes as they can be borne, but the food must be moderate and easily digestible until full convalescence has taken place. The flesh of animals killed while suffering from this affection has been eaten by man with impunity. COCCIDIAN ENTERITIS IN THE DOG. INTESTINAL COCCIDIOSIS. _Causes._ Two parasites have been found in connection with this disease in the dog; the =Coccidium penetrans=, already described, and the =Coccidium bigeminum=. =Coccidium Bigeminum, var. Canis.= This is elliptical and from 12 to 15 μ long by 7 to 10 μ broad. They are usually found in pairs lying side by side, and sometimes both in the same envelope indicating multiplication by division along the longitudinal axis. The bigeminum is held to be harmless, but the perforans, as in the cow and rabbit is very injurious and even fatal. The _symptoms_ are those of digestive disturbance, dullness, loss of appetite, retching, vomiting, colic and fœtid and bloody diarrhœa. Irritability, and a morose disposition and loss of control over the hind limbs have been set down as rabiform indications. _Diagnosis_ depends on the inveteracy and sanguineous nature of the diarrhœa, but especially on the discovery of the amœboid organisms in the recent, warm discharges. _Treatment_ should be along the same line as in cattle. COCCIDIAN ENTERITIS IN RABBITS. INTESTINAL COCCIDIOSIS. _Causes._ In rabbits the coccidium perforans is the psorosperm which usually attacks the bowels. The coccidium oviforme which produces hepatic coccidiosis is also occasionally found in the intestines. The perforans is smaller than in cattle being 15 to 25 μ long, by 12 to 15 μ broad, approximating to the variety found in man.
