FOR THE YEAR ENDING THE 31ST MARCH 1916.     11

       (2) Annual Report of the Superintendent, Civil Veteri-
nary Department, North-West Frontier Province, 1914-15:—

       " Two thousand seven hundred and fifty-eight vaccina-
tions against hæmorrhagic septicæmia were made in 28
villages and the results were satisfactory.

       "Five thousand five hundred and twenty-nine animals
were inoculated with hæmorrhagic septicæmia serum in 6
outbreaks. The results have been checked and appear satis-
factory.

       " In two outbreaks in which inoculations were carried out
indecisive results were obtained, i. e., after inoculation was
carried out neither inoculated nor uninoculated animals
developed the disease.

       "In four outbreaks positive results were obtained, i.e., un-
inoculated animals developed the disease while no inoculated
animals developed the disease."

       24. Charbon Symptomatique Vaccine. The outstanding
balance of vaccine from last year, having been manufactured
over three years previously, was discarded and a fresh brew
of 50,000 doses was prepared and thoroughly tested at the
Bareilly Laboratory. As the vaccine, to be of any protective
value, must contain living, though weakened, organisms of
the disease, great care is necessary to ensure that attenuation
has been carried sufficiently far to render the inoculation
safe but at the same time effective in producing immunity.
To confirm the laboratory tests, reports were asked for from
those officers to whom the new vaccine was sent and in all
cases the replies received were satisfactory; the following
extracts may be given as examples:—

       The Superintendent, Civil Veterinary Department,
Mysore, reports :—

       " That the results of inoculation with the latest supply
of black quarter vaccine have been successful and no com-
plaints were received from any places where cattle were
inoculated."
