Even making an allowance for the difference in the daily average strengths
of the two consecutive triennia (363.57 in 1921—23 and 388.12 in 1919—20)
there is no doubt that a remarkable reduction has taken place in the incidence
of tubercular infections. Therefore the prediction in the last triennial report
that the " arrangements for dealing with cases of tubercle now being satisfactory,
should markedly reduce the incidence of tubercular infections" has come
true. This gratifying result is almost certainly due to the excellent Tubercle
segregation wards designed and erected by Colonel P. F. Chapman, C.I.E , I.M.S.
Outside the institution, tubercle infection has increased rather than decreased
in Nagpur.
Malaria.
15. The total number of admissions for malaria is 21 against 36. Most of
the cases were due to Benign Tertian parasites ; only very
few were of Malignant Tertian type. No cases of Quar-
tan have been seen so far. The prophylactic use of quinine as a routine practice
has been abandoned, but rigid attention has been paid to anti-mosquito measures.
Quinine has been regularly administered only to those in whom malarial infection
is known to have occurred either by finding the parasite in the blood or by
enlargement of spleen, or both.
16. The use of cinchona ferbrifuge has been found most beneficial in
cases of malarial fevers due to Benign Tertian parasites. As this drug costs about
one-third of the price of quinine, the above measures have resulted in a consider-
able saving financially.
Ankylostome infection.
17. Among new admissions in 1923, the Hook-worm infection was 6.20
against 15.9 in 1922 and 11.11 in 1921. With a constant
supply of fresh cases from amongst new admissions and
on account of the fouling of barrack floors with fæcal matter, continuous
examination and repetition of treatment are necessary and this work goes on
continuously.
The triennial figures for percentage of Ankylostome infection amongst all
inmates are 10.02 in 1921, 3.80 in 1922 and 6.10 in 1923 against 8.85 in 1918,
13.82 in 1919 and 12.83 in 1920.
Treatment.
As a routine measure two treatments by means of Manson's Mixture were
carried out at half-yearly intervals during the period
under report. This is preferable to Oil of Chenopodium,
but it might be better still to use Carbon Tetrachloride in future.

The high mortality in the year 1919 at the Nagpur Mental Hospital has
been explained at length in the report of that year.
STATEMENT II.
Criminal lunatics.
19. On the 1st January 1921 there were 101 criminal lunatics, 53 were
admitted during the three years under report, making
a total of 154. Of these, 43 were discharged (15 dis-
charged cured, 10 sent back for trial, 4 returned to jail, 13 transferred to non-
criminal list and 1 discharged on security as improved) and 15 died, leaving a
balance of 96 at the close of the year 1923.
STATEMENT III.
Religion and sex.
20. Hindoos formed 81.19 per cent. of the total admissions during the
triennium, Muhammadans 15.14, Anglo-Indians 0.46
and Indians (Christians) 3.21. Percentage of male and
female admissions to the total admitted was 84.86 and 15.14, respectively, against
77.82 and 22.18 in the preceding triennium.
