540 SIMPLE COEYZA. 



Treatment. Whatever animal may be affected with coryza, 

 it will be benefited by warm clothing and the administration 

 of a dose of physic. Should there be any objections to the 

 purgative, doses of nitre or other neutral salt may be adminis- 

 tered daily. The diet must be restricted, and the nose steamed. 

 To steam the nose, large hot mashes are given to horses, 

 but I prefer a sack or nose-bag in which hay-seeds or bran 

 are placed, and over which boiling water is poured. Half a 

 pint of vinegar thrown on the steaming material renders the 

 application more active. A very good plan to perform this 

 operation consists in having a kettle to which a flexible tube 

 is attached. By boiling water in the kettle a jet of steam is 

 obtained, which can be directed into the nose, and according 

 to the distance that the tube is held from the nose, is the 

 temperature of the vapour applied to the schneiderian mem- 

 brane. Care must be exercised not to scald the latter. 



MALIGNANT CORYZA COEYZA GANGEENOSA. 



This has been called the glanders of the ox species. Con- 

 siderable confusion exists in the writings on malignant catarrh 

 of the horse and ox. Hering describes a malignant catarrh of 

 cattle catarrhus sinuum frontalium and a gangrenous form 

 of strangles, or coryza gangrenosa, affecting both horse and 

 cattle. The latter malady, it is evident, consists in the worst 

 form of the disease, known in Britain as purpura hsemor- 

 rhagica, though cases of oedema of the glottis in the horse 

 appear to me to be included under the head of gangrenous 

 coryza. I shall consider the specific and malignant catarrh 

 of cattle here, and speak of the other disease in treating of 

 the general disorders of animals. 



The malignant catarrh of the ox species occurs in the 

 spring and autumn, especially when there is much wet.
