183.  Research.—I have already referred to the difficulties in the way of
doing much research work under the present conditions. The following is a
short summary of the nature of the work engaged in during the year.

184.  Anthrax.—The following questions have been studied:—

      (1)  Susceptibility of the horse, cattle and sheep of India to experimental
            inoculation.

      (2)  The practical value of the use of Anti serum alone.

      (3)  Various methods of preparing a serum of high protective power.

      (4)  The immunizing properties of dead bacilli and other products of
            Anthrax cultures.

This investigation is being continued.

185.  Hæmorrhagic Septicæmia.—A similar consideration of the points
mentioned above under heading of Anthrax has been and is still in pro-
gress.

186.  Charbon Symptomatique.—The single vaccine prepared in pillule form
by Messers Parke Davis &Co., has proved a method extremely suitable to the
conditions of the country, and has met with the approval of the Superintendents
who have had occasions to deal with this disease. After numerous experiments
Captain Holmes has succeeded in preparing a single vaccine in pillule form to
be injected by means of an automatic Trochar and canula. The laboratory tests
of this vaccine have been very satisfactory as no casualties occur after its use
and an active immunity against the disease is established in from two to three
weeks.

A full report on this subject will be shortly submitted.

187.  Surra.—An outbreak of this disease on the Kathgodam-Naini Tal
road was investigated and experiment on the value of treatment of ponies and
other animals by means of various drugs completed. A report of this investiga-
tion was published in the Journal of Tropical Veterinary Science, Volume III,
No. 2. Experiments on the treatment and prophylaxis of surra are being
continued.

188.  As there was no officer available for field work and owing to want of
requisite material, no work was done on the following subjects included in the
programme of Research for 1907-08:—

      (1)  An investigation into the etiology, course and prevalence of "Kamri"
            or Paralysis among horses.

      (2)  Trypanosomiasis.

            (a)  The Natural History of the Trypanosome.
            (b)  The identity or otherwise of the Trypanosome infecting the horse,
                        ox and camel.
            (c)  The role played by biting flies in the spread of the disease, with a
                        study of such flies.
            (d)  The course of the disease in the camel.
            (e)  More definite information regarding the nature and extent of the
                        tracts in which the disease is prevalent.

      (3)  Piroplasmosis.

      (4)  The study of the effects and result of the use of the various protec-
            tive sera in the field.

189.  Cattle Lymphangitis.—In August 1907, a request was received from
the Senior Veterinary Officer, Bengal Command, to investigate the course of an
affection which had appeared among the transport bullocks at Calcutta and Dum
Dum. The result of the work on this subject has been published in the Journal
of Tropical Veterinary Science.
