8 THE PRACTICE OF VETERINARY MEDICINE, 



ficial. If the animal has been fed on food of a stimulating 

 character, it is good practice to give food of an opposite 

 character for a few days, as bran mashes, etc., then gradu- 

 ally revert to the original method of feeding. Should 

 recovery not progress in a satisfactory manner, or the 

 debility be well marked after the acute symptoms have 

 ceased, tonics, as iron, gentian, etc., should be given, and 

 the animal should have the best of food, and pure water in 

 liberal quantities. 



Results. — A great many diseases may follow simple catarrh 

 as a result of injudicious treatment, or treatment too long 

 delayed ; or may exist as complications. Some of the 

 complications and results of this affection are as follow : 

 pneumonia, pleurisy, pleuro-pneumonia, nasal gleet, laryn- 

 gitis, pharyngitis, laryngo-pharyngitis, bronchitis, etc., each 

 of which will meet with due consideration. 



LARYNGITIS 



Definition. — Laryngitis may be defined as an inflamma- 

 tory disease of the larynx, the inflammation involving the 

 mucous membrane only, in the greatest number of cases, 

 but sometimes involving the soft tissues as well, the 

 latter form being the most serious. Catarrhal laryngitis 

 is that form in which the mucous membrane alone is in- 

 flamed. 



Laryngitis is a very serious aflfection, and often termin- 

 ates fatally, sometimes within a remarkably short sj^ace of 

 time. In some cases a thickened condition of the mucous 

 membrane is caused by a copious and rapid effusion into 

 the submucous tissue, swelling is great, the laryngeal 

 muscles are greatly interfered with, or cease to act alto- 

 gether, the glottal oj^ening becomes partially or wholly 

 closed, and death takes place hy suffocation.
