Dear Sir, 



ALLOW me at prefent to trouble you with a few gene- 

 ral obfervations on natural hiftory, which I had an op- 

 portunity of making while on a botanical excurlion, with my 

 friend Mr Anderson, to the Dutch colony of Demerary. Gui- 

 ana is a country but little known in Europe, tlaoiigh its animals 

 and vegetables have added coniiderably to the catalogue of na- 

 tviral producflions. It is not however the organic kingdom which 

 I mean at prefent to touch upon ; all I aim at is to give you 

 fome idea of the face of the country, as leading to the know- 

 ledge of its formation and prefent flate. It is not a field for the 

 mineralogift, as its interior is unexplored. But to the geolo- 

 gift, who wilhes to trace revolutions of the lateft date, it is not 

 uninterefling to contemplate fuch a recent and fingular coun- 

 try as Guiana. 



I NEED not inform you, that under Guiana is comprehended 

 all the coaft of South America from the Amazons to the Oroo- 

 noko ; that it trends nearly N. W. and S. E, ; that it is in gene- 

 ral a very low and flat country, efpecially the Dutch or wefter- 

 moft part of it ; and that it is watered ;by feveral rivers and 

 creeks, which rife in a chain of mountains running nearly E.
