34.   (e) Diseases among serum makers and virus producers.—A
sporadic case of Anthrax occurred in the rinderpest virus camp on
the 20th November 1932 which was fortunately controlled without
further spread. An outbreak of Hæmorrhagic Septicæmia broke
out amongst the serum makers and resulted in eighteen deaths
between 10th and 19th February 1933. Prompt measures were
taken and the outbreak was suppressed without any serious inter-
ference with the work of the Institute.

                 IV.—INVESTIGATION AND RESEARCH.

                            (a) Rinderpest Investigation.

36.  A reference was made in the previous year's report to the
investigation of the incidence and the methods adopted for the
control of rinderpest in this Presidency, by a special officer
appointed for the purpose temporarily for a period of two years.
Mr. C. Suryanarayanamurti Pantulu Garu, Madras Veterinary
Service Officer, held this special post throughout the year under
report, and towards the close of the year he completed his investi-
gations and was engaged in the preparation of his report. Since
the close of the year, the Special Rinderpest Officer has submitted
his report and the report is being examined with a view to its
publication.

                        (b) Experiments with goat virus.

37.  During the year under report, experiments were conducted
on the use of goat virus in inoculating cattle against Rinderpest
as an alternative to serum simultaneous inoculations, and
Mr. R. Narasinga Rao, District Veterinary Officer. Madras, con-
ducted these experiments in his jurisdiction. The experiments
were conducted in ten villages and as many as 129 cattle were
inoculated with goat virus of which 84 reacted. It was necessary
to give serum to nine Mysore animals to modify the reaction
