Diagram illustrating death rates
from small-pox and degree of
protection afforded.
11. The diagram facing this page illustrates the death-rates from small-
pox in each district, the proportion of population
protected against the disease by vaccination during
the past seven years being shown side by side :—
12. Deaths from small pox.—The total number of deaths from small-pox
in the province during the year was 40,927 showing a ratio of .80 per mille of
the population against 31,614 and .59 of 1907-08. The largest number of
deaths was recorded in the districts of Gya (5,525), Patna (4,784), Shahabad
(3,465), Calcutta( 3,185), Saran (2,315), 24-Parganas (1,860), Howrah (1,846),
Ranchi (1,761), Midnapore (1,702,) Hazaribagh (1,505), Champaran (1,435),
Sonthal Parganas (1,301), Monghyr (1,266), Hooghly (941), Puri (849),
Burdwan (779), Palamau (741), Birhhum (715) and Balasore (696), while the
mortality was lowest in the districts of Darjeeling (9 , Khulna (63) and
Sambalpore (113). Out of 40,927 persons who died of small-pox, 18,843 were
reported to have been vaccinated mostly in their childhood or otherwise
protected, 13,702 unprotected and in 8,382 cases nothing could be ascertained.
These figures, however, are altogether unreliable, being recorded by the
illiterate choukidars and do not, therefore, serve as a guide in testing the
efficacy of vaccination in warding off small-pox.
13. In the animal Vaccination Depôts in Calcutta and Darjeeling 1,610
and 235 calves were vaccinated against 1,320 and 225 respectively of the
previous year. The quantity of lymph manufactured was 420,945 and 69,073
grains against 318,447 and 69,009 grains respectively in the previous year.
This shows that arm. to arm vaccination is being gradually, but steadily,
replaced by manufactured lymph.
Different methods of vaccination.
14. During the year under report 73,424 primary operations were performed
with lymph direct from calves, 10,58,995 with
lanoline lymph and 8,04,450 by the arm to arm
process, the corresponding figures for the preceeding year being 93,049,
7,75,319 and 9,79,753 respectively, excluding 44,820 cases of vaccination
in certain Tributary States of Orissa which could not be classified for
want of necessary information. The ratio per cent. of success under each
of these methods was 99.49, 98.09 and 98.77 as compared with 99.01,
98.59 and 98.99 respectively of the previous year.
The number of re-vaccinations under each of these processes of vaccination
was 8,301, 228,901 and 67,505 with a success of 76.83, 59.59 and. 83.41
per cent against 4,704, 107,697 and 53,029 with a success of 74.70, 64.77
and 75.73 per cent. respectively during 1907-08.

Darbar and the Sikkim State.
15. During the year 1908-09, 250 and 1,130 grains- of lanoline vaccine
