THE ANNALS OF APPLIED BIOLOGY 



In the Annals of Applied Biology papers will be published concerning the 

 economic aspects of agriculture, botany, plant-breeding, plant-pathology, mycology, 

 horticulture, forestry, helminthology, entomology, veterinary zoology, medical 

 zoology, and marine zoology. 



Contributors to The Annals are asked to send type-written articles if possible, 

 and as far as possible to make illustrations in a form suitable for reproduction 

 as text-figures. Lithographic Plates cannot be produced, except at the cost 

 of the contributor. Owing to the greatly increased cost of printing, authors are 

 requested to condense- their manuscripts as much as possible, confining themselves 

 to the description of new and important results, and to refrain from the inclusion 

 of figures that are not absolutely essential. The final decision, in such cases, rests 

 with the Editor (acting on the advice of the Publications Committee). Contributors 

 will receive free fifty copies of articles only. 



Editorial communications should be addressed to E. E. Green, at Way's End, 

 Camberley, Surrey.
