gated into a thick thallus. 
PREPARING FOR PUBLICATION. 
Dr. Johnston is preparing for the press a second edition of his 
‘History of British Zoophytes.’ It will be published by Mr. Van 
Voorst in a style to correspond with that spirited publisher’s series 
of ‘ Histories of British Animals,’ and will contain descriptions of 
all the species discovered since the publication of the first edition, 
with numerous additional plates.
