editing the Journal, and was succeeded by Dr. J. Frank 
Payne. Lankester and Payne added Mr. Thiselton Dyer 
(now Director of Kew Gardens) to their editorial body in 
1873, and he was succeeded in 1876 by Mr. Archer, of Dublin, 
the Secretary of the Dublin Microscopical Club, and the 
author of so many interesting discoveries among fresh-water 
Rhizopoda. In 1877 Dr. Payne retired, and Dr. Klein joined 
the editorial staff. 
In 1878 a further change was made. Professor Lankester 
became sole editor, with the co-operation of Archer, Francis 
Balfour, and E. Klein. This arrangement has continued ever 
since, with various changes in the list of those co-operating. 
Thiselton Dyer returned for a few years as one of those giving 
his co-operation ; and Moseley and Milnes Marshall have in 
turn assisted in the conduct of the Journal, and have published 
in it many of their most important papers, inducing their pupils 
to adopt the same mode of publication. 
The number of contributions which this energetic policy 
attracted to the Journal soon made it necessary to enlarge it ; 
and the term of Lankester’s editorship has been marked by a 
continuous increase in the amount of letterpress and in the 
number and excellence of the plates. This has of necessity 
been accompanied by a rise in price. The original price was 
four shillings per number—the numbers being issued quarterly. 
At that time the volume consisted of some eight-and-twenty 
demy octavo sheets and twenty plates, mostly also octavo. The 
last volume contained thirty-six royal octavo sheets and forty- 
two plates, many of which were coloured, while the majority 
were of quarto size. The change from demy to royal octavo 
was effected at the commencement of 1883, and in 1890 the 
strict quarterly publication of the Journal was abandoned, so 
that more than four numbers could be issued in the year. 
During the eleven years which have elapsed since 1883 sixty- 
one numbers, divided into fifteen volumes, have been issued ; 
so that the increase in size and price has not only affected the 
magnitude of each number, but has been accompanied by an 
increased rapidity of publication.
