previous year. As the statistics for 1902-03 relate to nine months only, i. e., from
1st April to 31st December 1902, no comparison of these with the present year's
statistics can be made. It is somewhat remarkable that in the Patna State
the re-vaccinations largely exceed the primary vaccinations; the high percentage
of success claimed in re-vaccinations suggests that many of the latter were really
primary operations. In the Patna and Bastar States vaccination appears to
flourish ; in Makrai, on the other hand, the work done was very inadequate, the
State officials do not appear to have given the assistance that might reasonably
have been expected from them.
The percentage of success claimed by Vaccinators was 97.98 in primary
vaccinations and 89.81 in re-vaccination against 97.78 and 87 97, respectively, in
the preceding year.

The use of glycerinated calf lymph has steadily increased and in 1904-05
more than three-fourths of the total operations were performed with it, the results
have been very satisfactory. In districts such as Betul, where the lymph was very
carefully prepared, practically all the primary vaccinations were successful and
sore arms were the exception. The Vaccination Manual referred to in paragraph 20
of the notes for 1903-04 has been distributed as proposed and orders were issued
for the cultivation of glycerinated calf lymph solely at Head-quarter stations. In
ten districts only were the arrangements carried out satisfactorily and in their
entirety, in the remaining eight districts they were carried out either partially or not
at all, the reason assigned being the difficulty of getting calves; with a little more
care and foresight it is not improbable that this difficulty could have been over-
come in most of these districts. Two specimens of the lymph were examined
at the Bombay Laboratory ; one sent from Betul was found to be of very good
quality, the report on the other, which was from Bhandara, showed that insuffi-
cient care had been used in the preparation of it.
In 1904-05, 6,076 calves were vaccinated in the Central Provinces and of
these 5,472 were used as vaccinifers; had the manufacture of glycerinated calf
lymph at Head-quarter stations been universal and otherwise satisfactory, it is
probable that one-fourth of the above number of calves would have sufficed.
10,334 calves were vaccinated in 1902-03 and 8,640 in 1903-04. The cost
incurred in connection with the preparation of calf lymph in 1904-05 was
Rs. 483-6-10 against Rs. 260-2-8 and Rs. 190-3-3 respectively in the two years
preceding.
In Berar lanolinated calf lymph only is used, and is prepared at the Amraoti
Depôt. 112 calves were vaccinated during 1904-05 of which 99 were used as vacci-
nifers ; the cost incurred in the preparation of the lymph amounted in all to
Rs. 1,112-1-5. The percentage of success attained with this lymph in 1904-05 was,
in primary vaccinations 97.45, in re-vaccinations 17.16 and in both combined 87.95.
From time to time and especially at the commencement of the vaccination season,
the lymph issued proved to be more or less inert, the use of glycerinated calf
lymph will now be extended to Berar.
17. The ideal to be kept in view is a central lymph depôt for the whole
Province, meantime glycerinated calf lymph will be prepared at Head-quarters
of districts (and for Berar Districts at Amraoti). It probably will be possible
