of fat and lard, as difficult of codtion, and favour^ 

 able to the difeafe. In the cure, he recommends 

 acids ; and fays, he ufed principally the vitriolic : 

 but above all he celebrates the praifes of four' 

 krout \ for the efficacy of which he alfo cites the 

 authority and experience of Sir John Pringle. 



He confiders the Fevers as arifing from impeded 

 perfpiration, co-operating with the effedls of cold, 

 moifl, and foul air and in this expedition^ he 

 thinks, the infufficiency of proper cloathing dur- 

 ing the watches might not unfrequently be found 

 a predifpofmg caufe. He is of opinion that the 

 difeafe was contagious j and fays, many were 

 cured by the early exhibition of emetics. In the 

 general method of cure, the pra6tice laid down by 

 our later writers in England was fuccefsfully pur- 

 fued. 



The Fluxes and Byfenteric diforders he afcribes 

 particularly to the prevalence of faline and putrid 

 acrimony in the food of feamen ; aided by foul air,, 

 and want of exercife, and propagated at length 

 by contagion too. 



Our author concludes, by fuggefting that there 

 are two caufes, of a general and permanent nature, 

 which predifpofe to thefe difeafes in all naval ex- 

 peditions. Thefe are, impure air^ and a conftanc 

 dcpreffion of fpirits in feamen, not hitherto fuffi- 

 ciently attended to, and inducing a degree of real 

 Noftalgia, He feems to be fufficiently aware 

 of the importance of corredting the firft, and re- 

 commends ftrongly the ufe of ventilators ; to the 

 other it is not eafy to apply a remedy. He informs 

 us, that both Swedes and Swifs find the greateft 



relief.
