‘« PARASITOLOGY,” a Supplement to the ‘Journal of Hygiene,’ has 
recently appeared (vol. 1. no. 1), and is published at Cambridge, at the 
University Press. 
When the ‘Journal of Hygiene’ was founded it was announced 
that papers on Parasitology ‘“‘in relation to hygiene and preventive 
medicine’’ would be published in its pages. It has, however, been 
felt for some time that the Journal 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. 
The remarkable development of parasitology in recent years, and 
the increase in our knowledge of the part played by parasites in 
human and animal diseases, demand a means of publication, in the 
English language, of original papers dealing with the subject in its 
widest sense. It is proposed in future to relegate all such papers to 
“ Parasitology.” 
The fundamental discoveries upon the modes of infection in 
plague, malaria, sleeping sickness, yellow fever, ankylostomiasis, 
elephantiasis, and other important diseases affecting man and animals, 
render it evident that the co-operation of specialists in different 
fields is required for the proper elucidation of the complex problems 
which surround the causation of these diseases. The successful 
study of such diseases as are carried through the agency of inverte- 
brate hosts demands, therefore, not only investigations into the pro- 
cesses which occur in the affected vertebrate, but also observations 
on the structure and life-history of the pathogenic organism, and of 
the alternative host or hosts which serve to spread the disease. 
Thus a knowledge of the structure and biology of mosquitoes, biting 
flies, and ticks is necessary for a comprehensive knowledge of the 
etiology of malaria, trypanosomiasis, spirochetosis, and piroplas- 
mosis, and a knowledge of fleas and their habits is essential in the 
study of plague. Further, recent discoveries relating to parasitic 
worms, especially those which produce filariasis, ankylostomiasis, and 
various intestinal diseases, have given a great stimulus to the study of 
the entozoa. |
