April.
6. Present spleen rates. —The town is divided into nine wards, but many
of them are again subdivided into quarters differing in their population and
other conditions. The spleen and parasite rates observed are given in Table I.

The spleen rate for the whole town averages 9%, but in five different areas
the rate was from 15 to 22 per cent, so these can be classed as areas of moderate
endemicity. (Spleen rate above 10%.) A further description of areas and
reasons for differences between them as regards malaria will be postponed until
after a second visit.
7. Type of Infection. —Benign tertian is the predominant type of the
parasite as will be seen from the following figures for positive bloods :—

The unusually high proportion of quartan infection is to be noted.
8. Anopheline mosquito breeding places. —Owing to an unusally advanced
dry season several places where there would have been collections of water in
normal years were dry, and mosquito breeding was limited to very few places
apart from wells. Of these, quite a large number are found in the older portions
of the City. The breeding places found, with the species occurring in each,
during the present survey are shown in detail in map I attached not reproduced.
Among these, the most important from the malaria point of view are
—
( a ) W ells. —W ells are particularly numerous in the more congested areas
of the Fort, Temple and the Godevari wards. Several of them are public wells
