collection. This tendency was to some extent fostered at 

 Rugby, but the influence exercised by Professor Henslow 

 during Berkeley's time at Cambridge, and the opportunities of 

 studying the progress of research made in the various branches 

 of Natural History, were the chief factors that determined 

 Berkeley to enter seriously on the study of what at the time was 

 styled Natural History. 



His first published paper was " On new species of Modiola 

 and Serpula" (Zoological Journal, 1828). It was followed by 

 "On the internal structure of Helicolimax Lamarckii"; "On 

 Dentalium subulatum " ; " On the animals of Voluta and 

 Assiminia" (idem 1832-34); and "On British Serpulae" and 

 " Dreissenia polymorpha " (Magazine of Natural History, 



1834-36). 



A series of beautifully executed coloured drawings and 



dissections, illustrating Berkeley's zoological studies, may be 

 seen at the Herbarium, Kew. Although all Berkeley's publi- 

 cations up to this time dealt with zoological subjects, yet the 

 study of Botany had been by no means neglected, and about 

 this time having made the acquaintance of Dr Harvey of 

 Dublin, Dr Greville of Edinburgh, the author of Scottish 

 Cryptogamic Flora, and of Captain Carmichael of Appin, N.B., 

 a trio of the most celebrated cryptogamists of the age, Berkeley 

 forsook the serious study of zoological subjects, and devoted 

 the whole of his leisure time to the lower forms of plant life. 

 Living at Margate, the marine algae naturally attracted Berkeley's 

 attention, and in 1833 he published his Gleanings of British 

 Algae, consisting of a series of detailed investigations on the 

 structure of the minute and obscure forms of marine and fresh- 

 water species. This work, illustrated by twenty coloured plates, 

 was originally intended to be included in the supplement to 

 Dr Greville's Scottish Cryptogamic Flora, but in consequence of 

 the discontinuance of that most excellent work, was issued as an 

 independent booklet. 



From the first Berkeley was deeply interested in the fungi, 

 and practically all his subsequent work was devoted to this 

 group of plants, and although well versed in general Cryptogamic 

 Botany, it was in the field of Mycology that his laurels were
