The Economical and Commercial uses and ad- 

 vantages arising from our Fisheries, have also 

 been dwelt upon, as far as was consistent with a 

 Work like this, while the structure and functions 

 of the finny race form an important feature in the 

 volume. 



We have much pleasure in announcing, that the 

 talents of Mr. K/. Schomburgk have been enlisted 

 for the Ichthyological department, and we hope, 

 very soon, to be enabled to lay before the Public a 

 volume written by this enterprising Traveller and 

 Naturalist. Mr. Schomburgk has spent twelve 

 years in exploring British Guiana, connecting his 

 geographical discoveries with those of the illus- 

 trious Humboldt ; and the subject of the volume 

 which we have now in view will be the History 

 and Descriptions of the FISHES of the ESSEQUIBO and 

 the RIVEES of BRITISH GUIANA. The drawings of 

 the various species have been all made and coloured 

 by the author on the spot, and from the fishes 

 newly caught, and will illustrate many new and 

 remarkable species. The rich and romantic scenery 

 of the rivers will be introduced as accessories to 

 the figures, also from sketches by the author ; and 

 the modes of fishing employed by the native 

 Indians, together with the tackle employed for the 

 purpose, will be given as additional illustrations.
