Price of Back Numbers. 
Owing to the great scarcity of many back numbers, Vols. 
I, III, VI, VII, X, XI, and XII are Out of Print, and the price of all 
back numbers still available is raised to 2/6 each (double numbers 
5/-). Vols. II, IV, V, VIII, IX, XIII to XVIII, £1 each. All 
enquiries are to be addressed to the Publishers, Messrs. Wesley 
and Son. 
Contributions. 
Contributions on all subjects connected with botanical science 
and teaching will be carefully considered by the Editor. 
A preference is given to contributions having more than a 
purely specialist interest. 
All MSS. must be easily legible. 
The number of separate copies required must be marked on the 
final proof. 
Illustrations* 
Whenever possible necessary illustrations should be drawn 
boldly on a large scale in Indian ink on Bristol board so that they 
can be directly reproduced on a reduced scale on zinc blocks, and 
appear as figures in the text. 
No half-tone shading or wash must be introduced into such 
drawings. Shading, where required, must be put in by means of 
separate dots or lines. 
Photographs will be reproduced by the half-tone or collotype 
process and will in most cases appear as plates. 
It is essential that the prints or negatives provided should be of 
good technical quality. 
Pencil drawings when necessary to illustrate microscopic 
preparations, etc., will be lithographed, and will appear as plates. / 
Not more than one octavo plate can be published in illustration 
of a paper, unless the contributor is willing to pay for the extra 
illustration. This rule does not apply to line drawings intended for 
reproduction as text-figures. 
Considerable and unnecessary trouble and expense are often 
caused by contributors sending in drawings in a form unsuitable 
for reproduction by the best and biost economical processes. The 
attention of contributors is called to the foregoing rules. In cases 
of doubt as to the best method of illustration, the Editor will always 
be glad to give advice if consulted beforehand. 
All communications on editorial matters are to be addressed to 
A. Q< Tansley, Grantchester, Cambridge.
