like a dog. On passing the catheter only a small quantity of urine was 

 drawn off. Temperature 38*9° C. (102^ F.) ; respirations 39 ; pulse 

 48. At midday temperature 39*3° C. (i02'7° F-) ; respirations 46; 

 pulse 75. Breathing remained difficult, and trembling of the muscles 

 attached to the olecranon was more marked. The horse drank a little 

 gruel and then lay down on its chest. It rose in a few minutes, the 

 face assuming an anxious expression, and again sat down on its hind 

 quarters like a dog. 



" Towards three o'clock it took a few mouthfuls of gruel, and once 

 more lay down. Ten minutes later it died without a struggle. 



" .4 utopsy. — Nothing in the peritoneal cavity ; little food in the intes- 

 tine ; the mucous membrane of the small intestine was congested in 

 places. The stomach contained a few quarts of liquid ; its walls were 

 contracted and wrinkled. The liver was large and yellowish brown in 

 colour. The kidneys were pale on section ; the pelvis of the kidney 

 contained a little viscous yellowish liquid. With the exception of a 

 small abscess in the anterior part of the right lobe the lungs were 

 normal. The bronchial glands were slightly swollen. Nothing ab- 

 normal in the bronchi or trachea. 



"The heart had stopped in diastole. The blood which escaped on 

 section was liquid and blackish, but coagulated rapidly. 



" The lower and lateral surfaces of the tongue showed several ecchy- 

 mosed patches, over which the mucous membrane was denuded of 

 epithelium. The epithelium covering the upper surface was at many 

 points greatly thickened. At the entrance to the pharynx were several 

 blind sacs (Morgagni's diverticula) ; the buccal mucous membrane 

 showed nothing unusual. 



" The mucous membrane of the pharynx was thickened, violet in 

 colour, ulcerated in places, and covered with whitish spots indicating 

 little abscesses developed in the submucous connective tissue. Gentle 

 pressure caused them to discharge thick yellowish-white fcetid pus. 

 The mucous membrane covering the anterior surface and base of the 

 epiglottis was also thickened and violet in colour. The arytaenoid 

 cartilages were of similar appearance. The mucous membrane of the 

 pharynx was in places three eighths of an inch thick ; its superficial 

 layer was hyperasmic, thickened, and infiltrated with offensive pus. 

 The subjacent muscles were similarly thickened, discoloured, and 

 whitish, and contained numerous small abscesses. 



"The retro-pharyngeal glands were as large as a hen's egg, and 

 contained purulent centres, some of considerable size ; all were filled 

 with whitish creamy stinking pus." 



This horse, therefore, died of diffuse inflammatory pharyngitis
