"118 animals—9 buffalo calves, 99 bovine calves, 1 donkey
and 9 rabbits were operated on, of these 3 buffalo and 1 bovine
calves were rejected on account of unsatisfactory results. Up to
the middle of February 1929 the Punjab method in which the
whole of the abdomen is scarified with a special fork shaped
scarificator was followed. In view, however, of complaints of
some vaccinators about the inefficacy of the lymph since the
middle of February a few animals were operated on by the old
method of putting linear incisions 1 inch apart. The lymph
collected from these animals when bacteriologically pure will be
compared with the lymph obtained by the Punjab method. The
Punjab method has been giving a very large amount of pulp per
calf and consequently has been very economical. It was intro-
duced on 19th January 1927 under orders of the then Director of
Public Health and has been responsible for a saving of about
Rs. 5,000 per annum to the Institute.

"This year almost every brew has been complained of as
weak by from 10 to 40 per cent of the vaccinators, although a
large majority have given good results.

"The Punjab method was introduced as an experiment and
at this stage I am not prepared to say that the bad results
obtained by a minority of the vaccinators is due to defect in the
lymph prepared by this method. Of course there are other causes,
as found by investigation in the working of the vaccinators at
Nagpur; and repeated experiments by my staff and myself at the
local centres go to prove that the lymph is not to blame.

"The average output of lymph was 75.35 grammes per bovine
calf, 51.43 grammes per buffalo calf and 2.35 grammes per rabbit.
The decrease in the yield from buffalo calves was due to linear
operation.

"The total yield of pulp was 7,672.22 grammes equivalent to
32,4623/1 c. c. or 649,255 doses against 8,619.67 grammes equivalent
to 36,778 c. c. or 735,560 doses of last year.

"The cost per dose of vaccine works out at five pies per dose.

"The average purchase price per calf was Rs. 12 and sale
price was Rs. 9 in round figures.

"The whole province of 22 districts, Feudatory States of
Raigarh, Sirguja, Bhopal, etc., Military Bodies, Railways, Jails,
Labour Associations and Mission Hospitals were supplied with
lymph on indents. The total supply of lymph to the province
was 688,855 doses against 650,490 of the last year. Of these, 606,475
doses were supplied to the vaccinators serving under various Local
Bodies and 82,380 doses to the Feuda ory States, Railways,
Military authorities and private practitioners, etc.

"Balance of lymph on hand on 31st March 1929 was
15,184½ c. c., i.e., 303,690 doses.
