In addition to the above, one cross-bred Friesian bull, two cross-bred
heifers and four cross-bred calves belonging to the dépôt live-stock died
from rinderpest.

During the year under review 20,961 grammes of crude lymph were
obtained from 566 successfully vaccinated calves giving an average of
37.0 grammes per calf as against 12,801.4 grammes from 307 successful
calves with an average of 41.7 grammes per calf in 1924-25 and 15,167.0
grammes from 328 successful calves with an average of 46.2 grammes
per calf in 1923-24. In 1925-26 the average yield of crude lymph
per cow-calf was 19.7 grammes and that per buffalo-calf 43.0, as com-
pared with 11.1 and 43.9 grammes, respectively, in 1924-25 and 18.4
and 52.7, respectively, in 1923-24. As in last year the decrease in the
average yield per calf was due to the calves supplied by the con-
tractor being of inferier class. During the year under review, 106,028
grammes of glycerinated lymph (of strengths varying between 1 — 3 to
1—7) and 3,741 grammes of glycerine paste were manufactured as
against 61,734 and 1,363.8 grammes, respectively, in 1924-25, and 80,314
and 1,643 grammes, respectively, in 1923-24. The policy of storing
lymph of a strength of 1—3 has been found satisfactory and will be
continued in future.

The table appended below exhibits the annual output of lymph, the
number of areas in which arm-to-arm vaccination has been replaced by
calf-lymph vaccination and the income and expenditure of the dépôt:—
