REPORT OF THE KING INSTITUTE, GUINDY
5. Yield of pulp.—The weight of the pulp to some extent also indicates the
potency of lymph. The average yield of pulp this year is 23.05 grammes as
compared with 23.5 last year and 22.07 the year previous. The average for the
years from 1904 to 1920 was about 5 grammes. In all 939 calves were used to
produce the required amount of lymph as against 916 last year and 998 the year
before.
6. Off season.—As in previous years, routine vaccination was suspended in
all the districts in the Presidency except the Nilgiris, the Shevroy Hills and the
Kodaikānal Taluk and Municipality. The actual period of suspension was the
same as that of last year. The exact period of the off season is not the same for
all districts. The off season for the Ceded Districts is from 1st March to 30th
June, and for the rest of the Presidency is from 1st April to 31st July. A
recent analysis of vaccination results by fortnights shows that the average worst
period for all the districts is from 15th March to 15th July, and that the worst
period for the Ceded Districts alone is a fortnight earlier from 1st March to,
30th June.
7. Quantity issued.—The total number of doses issued this year is 2,323,521
as compared with 2,216,038 last year and 2,224,080 the year previous. This is a.
record supply. Recipients are listed in Table II. It will be seen that there
is a slight increase in the amount taken by Municipalities and by Government
Departments and Jails. The increase in supply is mainly due to 135,000 doses
supplied to the Government of Bengal in April 1926. It was gratifying to be
able to meet immediately this unexpected demand.
8. Amount unaccounted for.— Only the returns received in the Institute till the
31st May are taken into consideration. The percentage of total lymph unaccounted
for is 20 as compared with 16.7 last year and 21.9 the year previous. As will be
seen in Table II, there was an enormous increase in the lymph taken by other
bodies, and as practically few returns are received from them, the percentage of
lymph unaccounted for in their case remains at the very high figure of 94.9. If,
however, the lymph issued to official and semi-official bodies in this Presidency
alone is taken into consideration, the figures for unaccounted lymph are 9.4 per
cent this year and 11.3 and 18.1 per cent for the last two years. There has been,
therefore, a further decrease of 1.9 per cent. In the following districts the
percentage unaccounted for exceeds the average 9.4 :—
