cessfuUy treated, into this it gradually merges. The chief dis- 

 tinguishing symptoms are the abundance and nature of the dis- 

 charge, the fetor of the breath, and the presence of the mucous 

 rale in the chest. It is one of the conditions known by the horse- 

 man's expression " thick tvind.''' 



Treatment. Like its type (dilatation of the bronchia, bron- 

 chiectasis) in man this disease obstinately resists treatment. In 

 our efforts to cure it the same general principles must be followed 

 as in acute bronchitis, with this grand qualification that the gen- 

 eral aim must be to stimulate and support. Stimulating liniments 

 may be repeatedly applied along the course of the trachea and on 

 the sides of the chest. An equable temperature is desirable and 

 a dry building. Water vapor medicated with various astringents 

 and antiseptics (creosote, carbolic acid, turpentine, tar, or tar 

 vapor) is to be commended. A course of tonic and expectorant 

 medicine is desirable and a highly nutritious and laxative diet is 

 imperatively demanded. 



As tonics Gentian may be given daily in 4 drachm doses com- 

 bined with quaiacum in do.ses of 2 scruples. In mcst ca.ses it will 

 be advisable to add to the above or employ separately arsenious 

 acid in doses of 5 to 10 grains combined with three times the 

 amount of bicarbonate of soda, and given daily for a month or 

 longer. 



The diet should be as for broken wind, nutritious, in small 

 bulk, of a laxative nature and given at least an hour before work. 

 A moderate supply of grass, roots, bran, oats or barley may be 

 given, but hay must be sparingly supplied and, if exclusively 

 clover hay, dry and dusty, is better withheld. In the north of 

 France horses with chronic bronchitis are maintained in a service- 

 able condition by a diet of cut straw and cut hay, well sifted to 

 remove all dust mixed with oats and molasses and set aside in a 

 large cask to ferment before being given to the animals. Tar 

 water may be the exclusive drink. 



A pint of linseed, well boiled, and given daily for a length of 

 time in succession is often of great value.
