142              Contagious Bovine Pleuro-pneumonia in British India

During these years, no separate entries of hæmorrhagic septicæmia were
made in disease returns. After this procedure was commenced in the year
1906, no further mention was made of bovine pleuro-pneumonia as a specific
disease entity. The remark of Joslen, Superintendent, Civil Veterinary
Department, Bombay, commenting on the returns of bovine pleuro-pneumonia
for the year 1903-04, is significant of the doubt already existing regarding the
correct diagnosis of cases accepted as contagious bovine pleuro-pneumonia.
He says, " I am doubtful if the diagnosis was correct in these cases. Conta-
gious pleuro-pneumonia I have not met with in the plains of India ". No
further mention of bovine pleuro-pneumonia is made from Bombay, until,
in 1928-30, when further cases are reported.

During the years 1931-32, contagious pleuro-pneumonia was reported
front Karachi district. Seven calves died out of eight attacked.

In 1932-33_; thirty deaths from bovine pleuro-pneumonia were recorded-
The fact that these cases were not accepted as hæmorrahagic septicæmia in-
dicates doubt as to the diagnosis of the type of pneumonia reported

In the year 1905, a separate entry is made for hæmorrhagic septicæmia
and, as no further reports are made of bovine pleuro-pneumonia, it must be
presumed that considerable doubt existed as to whether authentic contagious
bovine pleuro-pneumonia was actually a disease entity with which to reckon.
Trydell, Superintendent, Civil Veterinary Department, Bengal [1905] remarks,
" .... the machinery employed for the collection of these statistics has been
found to be insufficient to ensure even approximate accuracy ". This state-
ment, in conjunction with the fact that no further cases of bovine pleuro-
pneumonia were reported after 1905-06, is doubtless an indication of the
extreme caution taken in expressing an opinion regarding the actual existence
of contagious bovine pleuro-pneumonia,
