Overview -
This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1908 edition. Excerpt: ...to breed only in the water collected in the leaves of the parasitic Bromehaceae, and N. annulipts is said to breed in the sea. Fig. 68. Portion of Coolie Lines on a Tea Plantation, to shew different breeding-places of M. rossi, M. Hstoni, and N. maculatus S = M. rossi. = M. listoni and N. maculatus 2. Make a map of the neighbourhood, noting--(a) All breeding grounds. (&) What species are found breeding in those examined (Fig. 69). Fig. 69.

Determine the species, note relative numbers of each species on map. The relation of Anophelines to native dwellings will probably be evident. 2. In the dry season the search for Anophelines may be negative, and there may be no breeding-places. Make in the most sheltered places small cement pools, and keep these filled with water. After a certain number of days they may contain young Anopheline larvae if the adults are present in the houses. (It is necessary to be sure one's water supply does not contain young larvae or eggs).

In the conditions just described observe the pools made by the first shower of rain of the on-coming 'rains.' Note after three days have passed the presence of larvae in many of these. The distribution of Anophelines at the end of the Dry season will usually be found to'correspond to that of native huts. The Prevalence Of Malaria If we proceed to ascertain to what extent malaria prevails in a district we may attempt to do so in several ways. 1. We may consult hospital statistics and...
