The Journal of Agricultural Science 



Edited by Professor R. H. BIFFEN, M.A.. A. D. HALL, F.R.S., 

 and Professor T. B. WOOD, M.A. 



There is nut in Great Britain any general channel for the publication and discussion 

 of scientific papers bearing on Agriculture. These papers are often too technical for 

 publication in the journals of the societies devoted to pure science, and are not 

 sufficiently popular for inclusion in the Journals of the Board of Agriculture or of the 

 leading agricultural societies. The promoters of the present publication therefore 

 considered that the time had come for the issue of a Journal devoted wln)lly to 

 definitely scientific papers on agricultural .subjects. 



The Journal is thus mainly intended to circulate among agricultural teachers and 

 experts, farmers and land agents having an interest in the scientific side of their 

 profession, agricultural analysts, seedsmen, millers, manure manufactui-ers, etc., in this 

 and other English-speaking countries. 



The Journal is issued in quarterly parts. The current volume is Volume VI 



The subscription price, payable in advance, is 15«. net ($3.75) per volume (post-free) ; 

 single copies os. net ($1.25). 



Parasitology 



Edited by Professor G. H. F. NUTTALL, F.R.S., and A. E. SHIPLEY, F.R.S., 

 assisted. by EDWARD HINDLE, Ph.D. 



Extract from Frelhninary Editorial Announcement 



It has been felt for some time that the Journal of Hygiene was becoming unduly 

 burdened with papers dealing with the anatomy of mosquitoes, fleas, protozoa and other 

 parasites — of great importance in themselves — but having only an indirect relation to 

 hygiene and preventive medicine. 



AVe trust that Parasitology will fulfil the purpose the editoi-s have in view, of 

 encouraging the study of parasitology, especially in relation to disease, by providing 

 a means for the publication of papers relating to pathogenic and disease-transmitting 

 parasites, and that it will appeal not only to medical men at home and abroad, but 

 to veterinarians, zoologists and agriculturalists. 



Parasitology is published about four times a year. The current volume is Volume VII. 



The subscription price is £1. 10s. net ($7.50) per volume (post-free), payable in 

 advance; single numbers 10*\ net ($2.50), double numbei'S 20s. net ($5.00). Subscribers 

 to The Journal of Hygiene may become subscribers to Parasitology at the reduced 

 rate of £\. Is. net ($5.25) per volume.

 Biochemistry ate eligible for election. 



The annual subscription to the Society is 25s. ($6.25), which includes a copy of the
