ens as the malady progresses, and becomes dusky red with inter- 

 spersed claret-colored patches. (PI. IV, fig. 1.) Its lining membrane* 

 exhibits the following deviations from a healthy state : Ist. Its attach- 

 ment to the muscular coat is generally loosened, and at many points 

 destroyed. 2d. It is soft, easily breaks down under pressure, and 

 where the change is furthest advanced, peels off as if cohering me- 

 chanically to its sub-mucous connections. 3d. Its epithelium is imper- 

 fect, and at many points quite absent, thus forming cracks on its 

 surface. 4th. The high color of the tissue, as microscopically deter- 

 mined, is due, not as has been stated, to sub-mucous or intra-mucous 

 extravasation, but to vascular congestion in its most extreme form ; 

 the vessels being distended to their limits, but without rupture or 

 dispersion of their contents unless artificially produced. 5th. In some 

 instances, generally in cases examined a few hours after death, some 

 small ulcer-like depressed abrasions have been found. These are not 

 true ulcers, and do not penetrate beyond the epithelium. In other 

 instances black spots, without breach of surface and evidently due to 

 pigmentation, were met with. (Smart.) 



In simple cases, the fourth stomach is the principal seat of disease ; 

 the natural yellow or brown color of it is changed to a dark or mul- 

 berry shade ; the lining membrane is thickened and corrugated^ and in 

 cases which have been long suffering, there are often patches resem- 

 bling ulceration. A careful examination of this stomach proves the 

 morbid condition not to be the result of inflammation, but depending 

 entirely on an intense capillary congestion of the mucous coat, which 

 is found raised and separated from the muscular one beneath ; . . . the 

 peritoneal covering of the stomach is generally healthy, proving the 

 non-existence of inflammation. (Pallin.) 



The rennet stomach (laabmagen) and the thin guts (diinndarm) 

 always exhibit the most striking change ; on the outer surface they 

 are more or less discolored, covered with livid spots and bare places, 

 and when cut up the mucous membrane appears dark red, and covered 

 with a tough adhesive slimy fluid, discolored, frequently of a greenish 

 black. (Egan.) 



In the fourth stomach there is intense inflammation of the villous 

 membranes in patches, and every now aad then you see spots of ulcer- 

 ation. (Simonds.) 



III. The Intestines. These show a like congestive vascularity, 



• This is swollen, especially near the pylorns, and there is a singular mottUd aspect, when 

 closely observed, from the grayish epithelial deposit in the glandular openings. Erosions and 

 ulceration are not uncommon. Dr. Murchison says : '* The membrane is studded with numerous 

 minute superficial ulcers like those erosions which are so common in the ordinary cartarrhal 

 Inflammation of the human stomacb." (Qamgee's Cattle Plague, p. 69.)
