Dear Sir, Alderley, Augujl 15. 1791. 



I Have been prevented hitherto, by various occupations, from 

 acquitting myfelf of a promife you received from me, 

 (I am alhamed to think how long a time fince), that I would 

 fend you an account of the hot fprings in Iceland, from whence 

 the water was brought which you have lately analyfed. I have 

 trufted you would excufe a delay not altogether voluntary. It 

 will be now my endeavour to gratify your curiofity as far as I 

 am able ; and to acquaint you with every particular, as well 

 concerning the fprings as the country near them, which I think 

 you may find in the lead interefting. 



We faw many fprings in the courfe of our journey befides 

 thofe I am going to defcribe ; nor indeed are they confined to 

 the part of the ifland we vifited, but break out in every divifion 

 of it. For a general account of the moft remarkable, I refer 

 you to a letter, written by Dr Van Troil, (the prefent Arch- 

 bilhop of Upfal), to Profeffor Bergman, publifhed with fome 

 others concerning Iceland in the year 1777. 



The defcriptions given by this author are fo accurate, that 

 it will not be in my power to give you much new information. 



I
