Thefe clyfters did not remove the loofenefs, though 

 there was often a greater interval than ufual betwixt 

 the evacuations, after the injection of them. The 

 patient never complained of any uneafy distention of 

 the belly from the air thrown up, which, indeed, is 

 not to be wondered at, confidering how readily this 

 kind of air is abforbed by aqueous and other fluids, 

 for which fufficient time was given, by the gradual 

 manner of injecting it. Both thofe patients recovered, 

 though the ufe of fixed air did not produce a criils 

 before the period on which fuch fevers ufually ter- 

 minate. They had neither of them the opportunity 

 of drinking iuch wine as Mr. Lightbowne took after 

 the ufe of fixed air was entered upon ; and this, pro- 

 -bably, was fome difadvantage to them. 



I find the methods of procuring fixed air, and im- 

 pregnating water with it, which you have publifhed, 

 are preferable to thofe I made ufe of in Mr. Light- 

 bo wne's cafe. 



The flexible tube ufed for conveying the fume of 

 tobacco into the interlines, I find to be a very con- 

 venient inftrument in this cafe, by the method be- 

 fore-mentioned (only adding water to the chalk, be- 

 fore the oil of vitriol is inftilied, as you dire£t) : the 

 injection of air maybe continued at pleafure, without. 

 any other inconvenience to the patient, than wiiat 

 may arife from his continuing in one pofition during 

 the operation, which fcarcely deferves to be men- 

 tioned., or from the continuance of the clyfter-pipe 

 within the anus, which is but trifling, if it be not 

 ihaken much, or pufhed again fl: the reclum. 



When I faid in mv letter, that fixed air appeared 



to be the great eft corrector of putrefaction hitherto
