United Provinces.—From the year 1903, separate entries are made for
hæmorrhagic septicæmia, and it is not until the year 1905-06, that specific
mention is made of ' pleuro-pneumonia contagiosa '.

In the annual report for this year, the Superintendent, Civil Veterinary
Department, writes, " There is every reason to believe that tick fever fluke
disease, pleuro-pneumonia contagiosa, tuberculosis and trypanosomiasis
cause losses amongst cattle, but no reports of any of these have been received."

During the years 1906-37, sporadic cases of bovine pleuro-pneumonia,
presumably not related to hæmorrhagic septicæmia, are reported in bovines.

Central Provinces and Berar.—In 1902-03, Jethiji, the Superintendent,
Civil Veterinary Department, reports:

" Contagious bovine pleuro-pneumonia—a few cases have been reported
from Jubbulpore and Nagpur districts. I could not attend the outbreaks, so
that I cannot say definitely that the disease was the true contagious pleuro-
pneumonia or some other kind of pneumonia. Judging from the severity of
the outbreak and the high percentage of deaths, I am inclined to think that it
was the true Western Cattle Plague "

Three hundred and forty-one animals were attacked with a mortality of
sixty-three per cent.

In the following year, nine animals were attacked with the same disease
and eight died.

Until the year 1908-09, nothing further is heard of this disease, but in
this year Baldrey, Superintendent, Civil Veterinary Department,writes:
" Pleuro-pneumonia contagiosa has been reported in Nimar, but I have not
been able to verify it "

From that time, no more mention is made of the disease.

Assam.—There is no mention made of contagious bovine pleuro-pneumo-
nia until 1936. In October of this year, however, the Disease Investigation
Officer, Assam reported to the Imperial Veterinary Research Institute on the
occurrence of contagious bovine pleuro-pneumonia, without specifying the
particular tract of the country in which the disease outbreaks were noted.
The investigation at Mukteswar of this and succeeding outbreaks reported
from Assam constitutes the first serious attempt to elucidate, on a pathological
and experimental basis, the debatable question of the existence of contagious
pleuro-pneumonia in India.

The first batch of specimens received from Assam (October, 1936) com-
prised pleuritic fluid in sterile pipettes, ampoules containing similar fluid
preserved in 10 per cent. glycerine, and representative pieces of the lung
lesions in Zenker's fluid and 10 per cent. formalin.

The medium and methods employed for the cultural investigation of the
pleuritic fluid and identification of the causal organism, Borrelomyces peripneu-
moniae [Turner, Campbell and Dick, 1935] were those used by Bennet [1932]
in his work on the study of the organism.
