The object of the work, and the difficulties Mr. Berkeley 
labours under in the execution of it, are best expressed in that 
gentleman’s own words. “The drawings from which the 
present engravings have been executed, were prepared with a 
view to publication in the Supplement to Dr. Greville's 
Scottish Cryptogamic Flora; but in consequence of the dis- 
continuance of that most excellent work, there was no pros- 
pect of making them known except by giving them in a 
separate form, which the author is now enabled to do, through 
the kindness and liberality of Mr. Sowerby. He is well 
aware that they must lose much of the interest and power of 
instruction they would have possessed, if accompanied by Dr. 
Greville’s learned remarks, and illustrated by means of an 
extensive correspondence with the first continental Algolo- 
gists, and a possession of authentic specimens of most of their 
published species; but he is unwilling that the opportunity 
should be lost of recording and figuring as British, some new - 
and curious objects, in a field in which there are compara- 
tively few labourers; though by reason of the difficulty of . 
access to the several treatises scattered up and down in the. 
many journals of the day, consequent on a country residence, . 
he can make no pretensions to such a complete acquaintance 
with the most recent sources of information as would have 
enabled him with greater confidence to offer the present small 
contribution to the larger list of British Algae.
