Malaria, and eventually be in a position themselves to 
add new facts to our knowledge of this important 
disease. 
For instance, with very little apparatus it is 
possible to undertake many most important researches, 
e.g., to work out the rationale of infection in any station 
or cantonment; the form of the parasite present ; 
the percentage of adults and children infected ; the 
species of Anopheline ; where each species is found 
and where it breeds ; the percentage of each species 
carrying sporozoits and zygotes. 
In fact nearly the whole technique of Malaria 
can be conducted with a microscope, a few 7 slides and 
coverglasses, a needle, a stain, some tubes, pins, and 
cardboard. (Vide Appendix). 
While our original intention was to write a 
practical guide to Malarial Study solely, yet the 
opportunities for research on other blood parasites are 
so numerous in the tropics, that we have thought 
it to be of practical value to add short supplementary 
chapters on other Haematozoa and on the Trypano- 
somidae, etc.
