H^EMORRHAGIES. 259 



ing every means of moderating the haemorrhagy, and of pre- 

 venting its return, directed in DCCXCII. et seq., and these 

 precautions ought to be continued for several years after the 

 occurrence of the haemoptysis. 



DCCCCIL The phthisis which follows a suppuration from 

 pneumonic inflammation, can only be prevented with certainty, 

 by obtaining a resolution of such inflammation. What may be 

 attempted towards the cure of an abscess and ulcer which have 

 taken place, I shall speak of hereafter. 



DCCCCIII. I have said, it is doubtful if a genuine catarrh 

 ever produces a phthisis ; but have allowed that it possibly 

 may : and both upon this account, and upon account of the 

 ambiguity which may arise, whether the appearing catarrh be a 

 primary disease, or the effect of a tubercle, I consider it as of 

 consequence to cure a catarrh as soon as possible after its first 

 appearance. More especially when it shall linger, and continue 

 for some time, or shall, after some intermission, frequently re- 

 turn, the cure of it should be diligently attempted. The mea- 

 sures requisite for this purpose shall be mentioned afterwards, 

 when we come to treat of catarrh as a primary disease ; but, in 

 the mean time, the means necessary for preventing its producing 

 a phthisis shall be mentioned immediately, as they are the same 

 with those I shall point out as necessary for preventing a phthi- 

 sis from tubercles. 



DCCCCIV. The preventing of a phthisis from asthma must 

 be, by curing, if possible, the asthma, or at least by moderating 

 it as much as may be done : and as it is probable that asthma 

 occasions phthisis, by producing tubercles, the measures neces- 

 sary for preventing phthisis from asthma, will be the same with 

 those necessary in the case of tubercles, which I am now about 

 to mention. 



DCCCCV. I consider tubercles as by much the most fre- 

 quent cause of phthisis ; and even in many cases where this 

 seems to depend upon haemoptysis, catarrh, or asthma, it does 

 however truly arise from tubercles. It is upon this subject, 

 therefore, that I shall have occasion to treat of the measures 

 most commonly requisite for curing phthisis. 



" With regard to the cure of the tubercle, and the ill-condi- 

 tioned ulcer proceeding from the tubercle, we at present know
