cases are difficult of diagnosis, though a fair inference may be 

 deduced from the extreme severity of the symptoms, and the un- 

 usual degree of prostration which is present. When a pharyngeal 

 speculum, passing through the nose, can be availed of, it may 

 become possible to reach a more definite conclusion. 



Treatment. Beside the measures advised for catarrhal pharyn- 

 gitis (poultice, counter-irritants, laxatives, antithermics, alkalies, 

 etc. ), the main reliance must be placed on antiseptics. Persistent 

 inhalations of warm water vapor with carbolic acid, creolin, tar, 

 lysol, camphor or sulphurous acid are in order : also a mixture of 

 one or other of these agents or of boric acid, bisulphite of soda, ' 

 or salicylic acid in honey or molasses to be frequently smeared 

 on the teeth. One of the best agents is the saturated solution 

 of chlorate of potash in tincture of muriate of iron, of which a 

 drachm may be added to three ounces of water and given every 

 hour or two. Calomel may be injected through the nose during 

 inspiration, by means of an insufflator, care being taken not to 

 exceed the physiological .dose. Applications may be carefully 

 made on a bent staff as advised under catarrhal pharyngitis. 



PSEUDOMEMBRANOUS PHARYNGITIS IN CATTEE. 



Most common in calves. Inoculations successful on rabbits, mice and 

 sheep. Bacillus : its cultural characteristics. Predisposing causes. Symp- 

 toms : nasal mucosa congested ; false membranes ; snuffling, wheezing 

 breathing ; painful, rattling cough ; agonized expression ; salivation ; bowel 

 disorder. Course. Duration. Lesions : intense congestion and false mem- 

 branes. Treatment : as for horse ; special antiseptics ; solvents ; anodynes ; 

 tracheotomy. 



This has appeared especially in calves, and though apparently 

 readily transmissible among the young, it rarely attacks aged 

 cattle. Cadeac and others inoculated it on guinea pigs and rab- 

 bits without success. Dammann, on the other hand, had his 

 inoculated rabbits die in twenty-four hours with hemorrhages in 

 the seat of inoculation. Eoffler inoculated it hypodermically on 

 mice and produced extensive infiltration of the entire walls of the 

 abdomen, and often of the peritoneum including the surface of 

 the liver, kidneys and intestines, on which was formed a thick,
