The decrease in the issue of lymph in glass capillary tubes and the increase
in the supply in bulk are due to the introduction of the method of supplying
lymph in metal collapsible tubes which are cheaper than glass tubes. This method
has also resulted in the reduction of labour. The price of lymph issued in bulk
has therefore been reduced from Rs. 3 to Rs. 2 per drachm. Notwithstanding
the decrease in price, the receipts rose from Rs. 14,211 in 1910-11 to Rs. 18,780
in 1911-12 (Rs. 18,521 from sale of lymph and Rs. 259 from that of milk, &c.,)
excluding the cost (Rs. 68) of lymph issued free during the year, whereas the
expenditure amounted to Rs. 13,030 only in 1911-12 against Rs. 12,097 in the
preceding year.

All the 87 municipalities and 45 notified areas in these provinces received,
on payment, their supplies of lymph from the depôt during 1911-12 against 87
and 37 respectively in 1910-11. Arm-to-arm vaccination has now been replaced by
vacccination with calf lymph in 22 districts, nine districts having been added during
the year under report. Four districts received regular supplies in small quantities
in the latter part of the season. It is proposed to supply during the ensuing season
calf lymph to 11 additional districts, bringing the total up to 33 districts. Several
native states and the Chief Medical Officer, East Indian Railway, also purchased
lymph to the value of Rs. 1,079 in 1911-12 against Rs. 1,055 in 1910-11.

The total number of primary operations performed in these provinces in 1911-
12 with calf lymph was 764,699 and that of re-vaccinations 48,514 against 382,280
and 25,651 respectively in 1910-11. Returns of results have been received for
457,980 primary vaccinations and 27,852 re-vaccinations (excluding unknown cases)
and these show a percentage success of 90.7 and 44.2 respectively during the
period from April to September 1911 (hot weather) and 97.1 and 65.3 during the
period from October 1911 to March 1912 (cold weather) against 95.5, 56.1, 95.8 and
62.6 respectively in the preceding year. The strain of lymph was satisfactory.
In order to keep up its potency it was frequently fortified by passage through
rabbits. Experiments with Thermos flasks are still in progress.

Glycerinated calf lymph was supplied to all District Superintendents of
Vaccination, as usual, in time to start the seasonal work and the vesicle was
established in almost all districts on the due date.

The depôt was frequently inspected by the Sanitary Commissioner and
the Deputy Sanitary Commissioner, 2nd Circle, who is in charge of the institu-
tion.

From the statement of the above facts and figures it is evident that the work
of the depôt has considerably extended and is extending year by year. The staff
attached to the depôt requires strengthening and for carrying this out proposals
have been submitted to Government.
