Acute Catarrhal Enteritis in Solipeds. 231 



and glutinous, containing many granular and pus cells. The 

 villi are swollen, the follicles of Lieberkuhn puffed up, and the 

 agminated and solitary glands widely dilated, filled with exu- 

 date, and surrounded by an area of congestion. Proliferation of 

 small, round cells has produced embryonic tissue in the mucosa 

 iand especially between the glands. 



Symptoms.. In the mildest form there is hyperthermia, thirst, 

 insensible loins, scanty, high colored urine, costive bowels, a few 

 small pellets only being passed at a time, hard, dry and covered 

 with a mucous film, hot, clammy mouth, coated tongue, with 

 redness along the edges and tip, yellowish red eyes, impaired ap- 

 petite, dull, sluggish habit, a tendency to hang back on the 

 halter, and a steady loss of flesh and increased dryness and un- - 

 thriftiness of the coat. Slight, intermittent colics occurring es- 

 pecially after meals and attended by loud rumbling of the bowels 

 are marked features. This may be followed by slight relaxation 

 of the bowels and recovery in about a week, unless it should be- 

 come complicated by intestinal indige,stion or impaction, or 

 should merge into the acute form . 



In the more intense forms all symptoms are aggravated. There 

 is anorexia and even refusal of water, dullness and prostration 

 are well marked, the head carried low, and the gait is unsteady. 

 The mouth is hot with tenacious mucus, and a foetid odor ; the 

 tongue is furred and red at the tip and margins, the eye is 

 sunken, the conjunctiva icteric, the face pinched, and the pulse 

 accelerated. Hyperthermia may reach 104" F. Breathing may 

 be almost normal, or with fever, may become rapid and accom- 

 panied by a pleuritic ridge on the flank. The back is slightly 

 arched and rigid, the belly drawn up and tender, after meals it 

 may be tympanitic, and colics set in or are aggravated, pawing, 

 uneasy movements of the hind limbs, and lying down to rise 

 again shortly, with frequent looking at the flanks being notice- 

 able. 



Defecations are at first abundant and coated with mucus, later 

 the balls are small and scanty and expelled with much effort. 

 From the fir.st the everted rectum is of a very deep red. Toward 

 the end of the first day or later the intestinal rumbling inciea,ses, 

 flatus pas.ses freely, and diarrhoea may .set in and prove critical. 

 This usually indicates disea,se in the colon and tends to recovery ;
