affected, but if the condition extends to the capil- 

 lary a;r passages the above symptoms are much inten- 

 sified. The respirations are quickened and labored, 

 and the cheeks puff out at each expiration ; the 

 fever runs higher and the depression and general 

 constitutional disturbance become more marked. 

 The pulse at first is full and bounding, then becomes 

 quicker and weaker, and in cases approaching a 

 fatal termination is almost imperceptible. Percus- 

 sion gives negative results. In the first stage, 

 auscultation reveals that the respiratory sounds are 

 harsh and dry (bronchus rale) ; in the second stage 

 the mucous rale is well established, and the vascular 

 murmur intensified. An attack lasts two to three 

 weeks, and ends in recovery, chronic bronchitis, 

 catarrhal pneumonia, stenosis, or asthma. 



Treatment. — In smooth-haired dogs the thorax 

 should be covered with a costing of cataplasma 

 kaolini U. S. P. (or antiphlogistin, thermofuge, or 

 similar remedy), applied hot, and covered with a 

 thick covering of cotton wool, kept in place either 

 by a bandage or by a pneumonia jacket, which can 

 easily be made from factory cotton quilted with 

 cotton wool or batting. This application should be 

 removed and reapplied every twenty-four hours, for 

 two dressings. In animals covered thickly with 

 hair, oil of Sinapis, one part, and olive oil, forty 

 parts, well rubbed in, should be substituted for the 

 cataplasm, and the jacket applied as before. 



A purgative is always indicated in acute bron- 

 chitis, and may consist of one half to two grains of 

 calomel, repeated as occasion requires, it being most 

 important to stimulate elimination from the outset 

 of the disease. Unless the disease is of the well- 

 marked sthenic type and the fever extreme, the 

 coal-tar antipyretics, such as phenacetin and anti-
