periods they would he. attended with no danger, and, m the 

 severest cases, would leave nothing behind them but a slight 

 alteration in the features ; but ihe adynamic and ataxic 

 symptoms, which fVeque.atly render theni complex, con- 

 vert thcin into so destructive a malady, that they often re- 

 sist the most active and best admini-tertd medicines. Ino- 

 culation had much lessened the ravages of this destructive 

 scourge, and the immortal discovery of Jenner will extir- 

 pate the last roots of them. 



The distinguishing signs of peripneumony and pleurisy 

 are so uncertain that thev have been doubted by some cele- 

 brated physicians * ; they have been so often belied by ca- 

 daverous autopsia, my own experience has so many times 

 proved their insufficiency, and the principles of the treat- 

 ment are so identic, that T consider these two affections as 

 inseparable, and I unite them, after the example of Cul- 

 len t, under the name of pneurno7iia. 



In acute rheumatism nature is endowed with great energy, 

 which it is sufficient to moderate by diluents and severe 

 diet in order to obtain a speedy and happy termination. On 

 the other hand, in chronic rheumatism the re-action is 

 very weak ; the limbs are in such an inert state that it is 

 necessary to combat it by tonics given internally, and ap- 

 plied to the suffering parts : vesicatories, and friction with 

 alcoholic solution of cantharides, have justly acquired the 

 pre-eminence. The same means have sometimes produced 

 excellent effects in white swellings of the joints, which 

 often baffle the art of surgery. 



Hemorrhages occupy the third class, and are distinguished 

 into active and passive. Vesicatories are rarely indicated in 

 either ; and it is allowed to employ them only as revulsives 

 in certain cases of obstinate hcmoplysia. 



Of all diseases neuroses are those which present to the 

 philosophic physician the most afflicting spectacle, and that 

 most worthy of his meditation. He rejects with disdain 

 hypotheses more or less ingenious, and the arguments more 

 or less captious, of the subtle metaphysician enlightened 

 by the flambeau of analysis ; he seeks only in the nervous 

 system for the source of our mental faculties, since a slight 

 wound of the organ of the brain is sufficient to render the 

 mildest man furious, and to plunge the man of genius into 

 the most deplorable state of idiotism.
