to subscribers in the United Kingdom, and with a charge of is. 6d. per

postage 40 c. extra. Orders should be sent to Henry Frowde, Oxford 
University Press, American Branch, 91 and 93 Fifth Avenue, New York. 
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 
Farlow, 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 the 
illustrative figures should be planned so as to properly fill a 4to or an 
8vo plate. Attention to this will conduce to the rapid publication of the 
papers if accepted. 
Each contributor to the Annals of Botany is entitled to receive gratis 
twenty-five separate copies of his paper, and may purchase additional copies 
if he informs the Editors of his wishes in this respect when he returns 
corrected proofs. The price of these additional copies will depend upon 
the amount of text and the number of plates in the paper.
