According to ranges, 81,327 inoculations were performed
in the North Bihar Range, 187,789 in the Central and 47,705
in the Orissa Range. Details of the work according to each
district and disease are given in Table III.

53.  Rinderpest.—Protection was given by the " serum
alone " method and by goat blood and tissue virus methods,
the total number of animals protected against rinderpest during
the year being 258,022 as compared with 119,559 done in
1933-34. Of these, 94,888 animals were protected with anti-
rinderpest serum, and the remaining, 163,134 with goat blood
and goat tissue virus. The greatest number protected in any
one district by the ordinary serum alone method was 14,080
in the Santhal Parganas, while by goat tissue virus, the greatest
number was 23,625 in Gaya. Shahabad with a figure of 21,916
stood second in respect of goat tissue inoculation.

54.  Goat Virus Inoculation.—At page 15 of the Annual
Report for 1933-34 it was stated that further improvement of
this inoculation by adopting goat tissue virus was in contem-
plation. Though the starting of the work was considerably
delayed during my absence on leave it was undertaken
immediately on my return in November 1934. The (Veteri-
nary) Disease Investigation Officer was deputed to carry out
some preliminary tests concerning potency and reaction, etc.,
the results of which proving satisfactory, the Range Officers as
well as the Disease Investigation Officer were instructed to
push on with the campaign as vigorously as possible with the
existing subordinate staff. Within a short time it was found
that the method of immunisation by goat tissue virus was not
only a much simpler process but also much safer, and easier to
control than the blood virus one. The question of obtaining a
continuous supply was also solved as the Imperial Institute of
Veterinary Research had already put the tissue on sale at
Rs. 3-8-0 per ampoule of 100 doses. The blood virus was
therefore abandoned in favour of the tissue, and the result was
that in less than 4½ months, altogether 163,134 animals were
immunised both by blood and tissue virus.

55. It is worth noting here that the Director of the
Imperial Institute of Veterinary Research, Muktesar, reduced
the cost per ampoule of goat tissue virus from Rs. 3-8-0 to
Rs. 2-0-0 exclusive of the cost of a telegraphic advice which
was thought unnecessary, from the 1st March 1935, and that
the Government of India has just fixed its price at Re. 1-2-0
per ampoule. In view of the extremely low price now fixed
and the reliability of the supply from the Muktesar Institute,
it is no longer considered advisable to prepare the tissue virus
at the Bihar and Orissa Veterinary College as was contemplated.
