IN a paper publiflied in the fecond volume of the fecond de- 

 cade of the Medical Commentaries of Edinburgh, I men- 

 tioned a defign of endeavouring to trace the influence of a cold 

 climate on the human body and its difeafes, which fhould form 

 a contrail with the many accounts publifhed of late years rela- 

 tive to the eflFedls of hot climates ; and I likewife mentioned my 

 having given a detached piece *, fome years ago, at a com- 

 mencement of the fubjedl, in the fixty-eighth volume of the 

 Philofophical Tranfad\ions of London, which contains matter 

 necefTary to illuftrate fome parts of the following Diflertation. 



I WAS induced to this defign, by having met with nothing of 

 the kind in the courfe of my reading ; and by remarking that, 

 whilft warm countries feem to occupy the attention of many 

 of the Faculty, the more northern regions appear to intereft 

 but very few of our learned brethren, although it is but natu- 

 ral to conclude that if one extreme of temperature is found to 

 have much ^influence, the other can fcarcely be entirely with- 

 out it.

 Natives of Ruflia.
