catarrh and anthrax. Dieckerhoff describes exudates, ulcera- 

 tions and even perforations in pseudo-diphtheritis, and Briick- 

 miiller, congestions and ecchymoses in connection with a cutaneous 

 rash. Tuberculosis of the organ is somewhat rare and is held to 

 be due to the swallowing of bronchial secretions in cases of pul- 

 monary tuberculosis. 



Cases of primary inflammation are rare, in keeping with the 

 soft finely divided condition in which the food reaches the organ. 

 It may, however, occur in case of the ingestion of arsenic and. 

 other irritant poisons, or of goring, kicks and other injuries on 

 the right hypochondrium, or from the irritation attendant on im- 

 paction, or again from the stimulus of a sudden change to rich 

 green food. 



The lesions in such a case are congestion of the folds with 

 patches of ramified redness, blood extravasations, desquamation, 

 softening or even gangrene. False membranes, perforating 

 ulcers, and erosions are .sometimes present. In the chronic forms 

 grayish or .slate colored pigmentation of the mucosa, congestions 

 and papillary growths are common. 



In both acute and chronic forms the congestion entails loss of 

 contractility and thus impaction and drying of the ingesta between 

 the folds of the organ are constant. 



Symptoms. These are the symptoms of impaction of the 

 manifolds, impaired appetite and rumination, formation of solid 

 masses in the rumen, tympany, tenderness or pressure on the 

 right hypochrondrium, irregularity of the bowels, arching of the 

 back and grunting when made to walk. The addition of fever, 

 as evidenced by rectal hyperthermia, hot horns, ears, legs and 

 muzzle, serves to diagnose it from simple impaction. 



The course of the malady is the same as in impaction, but with 

 an even greater tendency to aggravation and a fatal result as the 

 inflammation entails a paresis of the walls of the viscus which 

 favors a constant accumulation and dessication of the interlaminar 

 material. 



Treatment. This must be largely on the .same line as in im- 

 paction, laxatives of sulphate of soda, a diet of flaxseed or barley 

 gruel, and drinking water rendered demulcent with slippery elm. 

 These must be supplemented by a mustard or other blister to the 

 right hypochondrium, by soothing doses of nitrate of bismuth
