222. The serum was also used in an outbreak of Anthrax among the Poona
Horse. The return furnished by the Veterinary Officer shows that from
January to May 1908, 74 horses and mules had been attacked. On 21st May
inoculations with the serum were commenced and continued up to July. From
the former date, four cases occurred in June among the non-inoculated, and
among the inoculated three were attacked more than three weeks after the
serum injection. No further cases were recorded.
HÆMORRHAGIC SEPTICÆMIA.
223. The preparation of anti-serum or vaccine of high protective power
was under investigation. A serum has been prepared which in doses of
5 to 10 c. c. affords complete protection against the inoculated virus for a period
of six weeks, also a dead vaccine which protects for a period of two to three
months. These products are under trial as to their suitability for field opera-
tions. The serum is not likely to be of much use but the vaccine may be,
if used during the rains in villages where the disease is enzootic. 5,140 doses
of the new vaccine were prepared and 3,500 doses issued on trial.
224. The following statement shows the results of injections carried out in
the field both with the old Anti-Serum and vaccines:—

225. The Imperial Bacteriologist remarks: "With regard to the efficacy
of Hæmorrhagic Septicæmia vaccine, the Superintendent, Civil Veterinary
Department, United Provinces, reports that he tried the Vaccine in an outbreak
in which 10 animals had died in. two days and 4 were sick. One hundred
healthy animals were vaccinated and the village kept under observation for three
months, but no deaths were reported, except two sick animals (uninoculated)
during that interval."
CHARBON SYMPTOMATIQUE.
226. A method of preparing a single vaccine in pillule form has been
worked out. The vaccine was tested by a large number of experiments
and gave good results. One thousand eight hundred and sixty doses were
prepared and 1,310 doses issued to various Superintendents of the Civil
Veterinary Department. A special Injector for inoculating the pillules is also
supplied with the vaccine.
227. Attempts are now being made to prepare the serum recommended by
Leclainche for immunizing against Charbon Symptomatique. This has been
asked for by Major Walker for use in actual outbreaks and would prove of great
value if used in combination with vaccine in certain cases.
228. Blacklegoids have been largely used in the Punjab and North-West
Frontier Province for protecting animals against the disease, and the following
