NOTICE TO SUBSCRIBERS. 
The subscription-price of each volume is thirty shillings, payable in 
advance: the Parts, four in number, are supplied as they appear, post free 
to subscribers in the United Kingdom, and with a charge of is. 6 d. per 
annum for postage to subscribers residing abroad. The price of individual 
Parts is fixed at a higher rate. Intending subscribers should send their 
names, with subscription, to Henry Frowde, Oxford University Press, Amen 
Corner, London, E.C. 
As the earlier volumes of the Annals of Botany are becoming scarce, 
Vol. I will only be sold as part of a complete set; and Parts will not 
as a rule be sold separately, after the publication of the volume to which 
they belong. A few extra copies of particular Parts at present remain 
on hand, for which special application must be made to the Editors, 
Clarendon Press, Oxford. 
NOTICE TO CONTRIBUTORS. 
Contributors in America should address their communications to Professor 
Thaxter, Harvard University; and all other contributors to the Editors, 
at the Clarendon Press, Oxford. 
Papers sent in with a view to publication must be type-written and must 
conclude with a summary of the contents. The illustrative figures should be 
planned so as to fill properly a 4to or an 8vo plate. The maximum 
space available for figures in a 4to plate is 8^x11^ inches, in an 8vo 
plate 8J x 5 J inches. Attention to this will conduce to the rapid publication 
of papers if accepted. 
Each contributor to the Annals of Botany is entitled to receive gratis 
one hundred separate copies of his paper, and may purchase additional copies 
if he informs the Editors of his wishes in this respect when he returns cor¬ 
rected proofs. The price of these additional copies will depend upon the 
amount of text and the number of plates in the paper.
