    The sick-rate from kala azar in this village at the time of examination
was therefore17 per cent. of the population examined, and the death-rate for the
previous year was 5.6 per cent.

    Prevalence of malaria in Ulloobari village.—This was estimated by an
examination of children, with the following result :—

Number of children under
10 years of age
examined.
Spleen rate per
cent.
Malarial parasite-rate per cent.
(endemic index).
Varieties of parasites found.
40 32.5 12.5 Three cases of Simple
Tertian infection; two
cases of Quartan infection.

    Conclusion.—Out of a total of 123 people examined, at least 21 were suffer-
ing from a deadly disease known as kala azar. The village in which this disease
occurred was so slightly malarious that only about 12 per cent. of the young
children were infected with malaria parasites.

    3. TEZPUR IN THE DISTRICT OF DARRANG IN ASSAM.—It was seldom
possible to walk through this town without meeting several persons suffering from
kala azar, and in a later part of this report I shall give particulars of a number
of cases studied at the local dispensary. By far the greater number of patients-
attending at this institution on account of fever and enlargement of the spleen
were suffering, not from malaria, but from kala azar, the former disease being so
uncommon that often several days elapsed without a single characteristic
case being seen. During one of my walks through the town I was able
to examine and take slides of finger blood from 15 young children living
in the neighbourhood of houses occupied by persons suffering from kala
azar. No one of the children had an enlarged spleen, and in no slide were
malaria parasites found. Experience in other parts of India has taught us
that, if this neighbourhood had been at all malarious, it would have been
impossible to examine the blood of 15 young native children without finding
malaria parasites in at least two or three, and we are forced to conclude that,
as in other instances, kala azar existed here in a place which was only very
slightly, if at all, malarious.

    4. KOHBARI VILLAGE NEAR TEZPUR.—This small isolated village, situated
on a bank of the river Brahmaputra near Tezpur, afforded an even better
example of a place where kala azar existed in the absence of malarial fever
