cutaneous eruption, while in winter the eczema moderates and 

 bronchitis comes to the front. 



Course. Prognosis. The disease being so frequently the con- 

 sequence of age, idleness and obesity, it is of an obstinate char- 

 acter, and too often proves altogether incurable. 



Lesions. These are the common attendants on bronchitis, ex- 

 cept in the matter of congestion and redness. There is usually 

 emphysema, the affected lobuletes projecting beyond the average 

 level, and of a very pale color ; collapse of certain lobuletes 

 marked by flattening and flesh-like color ; dilatations of the 

 bronchia with accumulations of more or less tenacious exudate ; 

 constriction of the bronchia from peribronchial exudation and 

 hyperplasia, and it may be thickening of the bronchial mucosa 

 itself. The mucosa is uneven in outline, of a dull gray color, 

 and it may be covered with minute papillary hyperplasia. As 

 in acute bronchitis, bacteria are invariably found in the diseased 

 tissues and discharges, and contribute largely to the obstinacy of 

 the case and the difficulty of treatment. 



Treatment. For successful treatment the first consideration is 

 the removal of those causes that lay the system open to the 

 affection and serve to maintain it. If the patient can be put on 

 a simple and restricted diet and, in a genial season, can have 

 abundant out-door exercise, the obesity may be reduced and 

 digestive and hepatic functions improved. Even when a patient 

 is not at first able to take active exercise, he may be taken out 

 in a carriage until he gains vigor enough to run by himself. In 

 the same way regular warm baths'(70° to 80°) and liberal mas- 

 sage daily may greatly reduce corpulency and improve the 

 health. In an acute access, however, exposure in cold weather 

 is to be carefully avoided and a moderate even temperature 

 secured. In such cases massage and mild saline laxatives 

 (Rochelle salt) daily will serve a good purpose. To dissolve and 

 loosen the expectoration we may use expectorants (ipecacuan, 

 Dover's powder, apomorphia, senega, liquorice, horehound), or 

 the more stimulating expectorants (turpentine, terebene, balsam 

 of Peru, or Tolu, or anise). 



Inhalations of tar, turpentine, carbolic acid, creolin, cresyl, 

 lysol, eucalyptol may be of great use. 



When the cough is very annoying, calmatives and sedatives
