It is apparent from the above—(1) that
lanoline lymph at present consumed
only by a few municipalities in the Mid-
napur and Hoogly districts is falling
into disrepute, (2) that while the per-
centage of success with glycerine lymph
increased in primary cases during the
year under review, it decreased in re-
vaccination cases. The high percent-
age of success as reported in re-vaccina-
tion cases with lanoline lymph is ex-
tremely doubtful and requires careful
investigation.
16. Inspections.—The Statement No.
V attached to this report shows that the
District Health Officers, including the
Civil Surgeons of Darjeeling and Chit-
tagong Hill Tracts, inspected 56,896
primary and 17,919 re-vaccination oper-
ations, or 3.4 and 1.7 per cent. of the
total number of vaccinations. Of the
total number inspected 96.9 per cent. of
primary vaccinations and 52.4 of re-
vaccinations were found to have been
successful. The District Health Officer,
Hooghly, inspected 15.5 primary vacci-
nations and 17.3 re-vaccinations per
cent. of the total operations performed,
Burdwan 11.2 and 10.2 and Chittagong
12.6 and 6.1 per cent. respectively.
The District Health Officer of Mymen-
singh inspected .7 and .4, Murshidabad
.6 and .1, Birbhum .5 and .7, Bakar-
ganj .4 and nil and Jalpaiguri .2 and
1.6 per cent. operations
respectively.
The inspections made by other District
Health Officers fluctuated between the
above two extreme percentages.
The provincial vaccination inspecting
staff inspected 674,546 primary and
122,578 re-vaccination cases or 52.8 and
12.1 per cent. of the total operations
performed in the
Presidency. The
Municipal Superintendents of Vaccina-
tion and Municipal Sanitary Inspectors
inspected 42,098 primary and 123,354
re-vaccinations or 2.5 and 12.2 per cent.
of the total number.
17. Bengal Vaccine Depôt.—The
total number of calves vaccinated in the
Bengal Vaccine Depôt during the year
under report was 2,440 against 2,272
and 2,726 during the two preceding
years. The total output of lymph dur-
ing the year was 1,975,780 grains
against 1,694,180 and 1,706,089 grains
during the two preceding years. The
output of the year supplemented with
the reserve of 74,869 grains of last year
amounted to a total of 2,050,649 grains,
of which 2,029,178 grains were actually
issued against 1,764,339 and 1,563,861
respectively during the two preceding
years, leaving a balance of 21,471 grains
only at the close of the year. Only 8,880
grains of lanoline lymph were manufac-
tured during the year, which with the
last year's balance of 2,805 grains in
hand amounted to a total of 11,685
grains out of which 11,443 grains were
expended during the year. The aver-
age yield of pulp per calf was 182.14
grains against 168.06 and 152.76 grains
of the two previous years. Owing to
the unusually heavy demands to meet
the anticipated epidemic of small-pox,
great strain was thrown on the Depôt
and the necessity of building up a very
large reserve for future occasions was
actually felt for which necessary steps
have now been taken. Various other
improvements both technical and struc-
tural are also in hand, the chief of
which is the building of a separate shed
for those calves that have passed the
period of quarantine and are waiting for
vaccination.
18. General
Remarks—In
1913
when I was first appointed as Deputy
Sanitary Commissioner to the Dacca
Circle, with the special object of looking
into the vaccination arrangements that
were then obtaining in the districts of
Dacca and Chittagong divisions, mostly
populated with Musulmans who on the
basis of so-called religious objections,
offered the most obstinate and violent re-
sistance to vaccination, the local Gov-
ernment, at the instance of Colonel
Clemesha, the then Sanitary Commis-
sioner for Bengal, had sanctioned the ap-
pointment of two Special Inspectors of
Vaccination out of which only one, a
Haji Jan Khan, an up-country man,
was appointed. He was specially selec-
ted by Colonel Clemesha for his experi-
ence in vaccination work and his daring
