 ings. 8vo., cloth.

 same Author, 



A HISTORY OF THE 



BRITISH SPONGES AND GORRALLINES. 



To be Printed and Illustrated in the same style as 

 the History of the British Zoophytes, to which 

 this new AYork may he considered a Supplement, 

 and as completing our original design. It will 

 contain a very full account of all that has been 

 hitherto written on the subject ; and an original 

 figure of every species and remarkable variety 

 will be given. Dr. Johnstone intends, at the 

 same time, to avail himself of this opportunity of 

 adding many new figures of Zoophytes, contri- 

 buted by his friends, and acquired by himself, 

 since the Volume on British Zoophytes was 

 Published.
