pslled with sneezing and accompanied by movement of the jaws. 

 With the access of free secretion there is a great mitigation of the 

 fever and the other distressing symptoms, and, if no relapse nor 

 compHcation supervenes, recovery may be complete in a fortnight 

 or three weeks from the onset. 



From this time all the febrile symptoms decline and disappear, 

 appetite and liveliness return, the discharge rapidly diminishes 

 and finally disappears, when the patient may be said to have com- 

 pletely recovered. 



Capillary and pseudo-membranous bronchitis are described 

 by Reynal as occurring in young horses recently brought into the 

 army and subjected to the hot and close stables in some of the 

 French barracks. It began as ordinary bronchitis, which in place 

 of tending to recovery, propagated itself to the most minute 

 bronchial ramifications, and was frequently complicated by the 

 formation of false membranes. The signs of its accession are an 

 extreme intensity of the general symptoms, the rapid, labored, 

 difficult breathing, accompanied by convulsive action of the 

 pectoral and abdominal muscles ; the frequent, painful, suffocating 

 and abortive cough, which violently shakes the whole body ; the 

 extended head, open mouth, distorted nostrils, reddish brown 

 protruding eyes ; the pinched, haggard features, and the frothy 

 mucous, nasal discharge striated with blood, and later interspersed 

 with shreds of false membrane similar to those existing in croup. 

 In connection with these are the symptoms of extreme oppression , 

 partial sweats, tumultuous action of the heart and small, weak, 

 rapid pulse. Death resulted from suffocation during a paroxysm 

 of coughing. 



Course. Duration. Termination. Bronchitis is not usually 

 fatal, except in very young or old or worn out animals, or unless 

 it assumes the capillary form or is complicated by pneumonia, 

 pulmonary abscess or by metastasis to the bowels or feet. In the 

 mildest cases health is re-established in three or four days, and in 

 the severe, about the twelfth, fifteenth or twentieth da3^ In old 

 and debilitated animals in which pure bronchitis proves fatal, the 

 abundant effusion into the bronchial tubes, the influence of gravi- 

 tation retaining this in the smaller tubes, the palsy of the 

 cilia which normally carry it outward, and the want of power to 

 expectorate by coughing, usually bring about suffocation. This
