glottis. The cough is generally at first dry, occasioning pains 

 about the chest, and more especially in the breast. Sometimes, 

 together with these symptoms, pains resembling those of the 

 rheumatism are felt in several parts of the body, particularly 

 about the neck and head. While these symptoms take place, 

 the appetite is impaired, some thirst arises, and a general lassi- 

 tude is felt over all the body. 



MLI. These symptoms (MXLVIIL ML.) mark the vio- 

 lence and height of the disease ; which, however, does not com- 

 monly continue long. By degrees the cough becomes attended 

 with a copious excretion of mucus ; which is at first thin, but 

 gradually becoming thicker, is brought up with less frequent and 

 less laborious coughing. The hoarseness and soreness of the 

 trachea likewise going off, the febrile symptoms abating, the 

 cough becoming less frequent, and with less expectoration, the 

 disease soon after ceases altogether. 



MLII. Such is generally the course of this disease, which is 

 commonly neither tedious nor dangerous ; but, upon some oc- 

 casions, it is in both respects otherwise. A person affected 

 with catarrh seems to be more than usually liable to be affected 

 by cold air ; and in that condition, if exposed to cold, the dis- 

 ease, which seemed to be yielding, is often brought back with 

 greater violence than before, and is rendered not only more te- 

 dious than otherwise it would have been, but also more danger- 

 ous by the supervening of other diseases. 



MLI II. Some degree of the Cynanche tonsillaris often ac- 

 companies the catarrh; and when the latter is aggravated by a 

 fresh application of cold, the cynanche also becomes more vio- 

 lent and dangerous, in consequence of the cough which is pre- 

 sent at the same time. 



MLIV. When a catarrh has been occasioned by a violent 

 cause ; when it has been aggravated by improper management ; 

 and especially when it has been rendered more violent by fresh 

 and repeated applications of cold, it often passes into a pnea- 

 monic inflammation, attended with the utmost danger. 



MLV. Unless, however, such accidents as those of MLII. 

 MLIV. happen, a catarrh, in sound persons not far advanced 

 in life, is, I think, always a slight disease, and attended with lit- 

 tle danger. But, in persons of a phthisical disposition, a ca-
