10. Tuberculine.—Only 40 doses of this material have been asked for
during the year.
11. Tetanus anti-toxin.—This anti-toxin has been prepared for the first
time at the laboratory this year and 22,164 c. c. are ready for testing. It will
prove very useful in places where Tetanus is prevalent after injuries and
operations, Bombay for instance. So far the demand has been small, but
probably it will be required in moderate quantity as the operations of the
Department extend.
12. Mallein.—The demand for Mallein increased considerably, 7,220 doses
were asked for. The supply from outside sources has now been discontinued.
13. Cost of serum.—Calculated on the total expenditure of the Laboratory,
the cost of serum, per dose, is only 3 annas 8 pies which is very cheap com-
paratively.
14. In addition to the administration and general routine work, such
time as has been available has been devoted to research work. It has been
ascertained that serum kept at Karachi for two years had lost 55 to 60 per
cent. of its protective power. An opportunity was taken to inoculate an
elephant with a large dose of rinderpest blood to ascertain whether she would
take the disease. The result was negative, which proves that she possessed
either natural or acquired immunity.
15. Spirochætosis is reported in cattle.
As opportunities offered,
Piroplasmosis and Trypanosomiasis in bovines was studied.
16. Some experiments in the treatment of Trypanosomiasis (Surra) by
the administration of Atoxyl were carried out ; further experiments are
required in this direction. The susceptibility of the Indian elephant to Surra
(Equine) was tested and the results point to the conclusion that old elephants
have considerable or total immunity to the disease.
17. Experiments were also made to ascertain whether Equine and
Cameline Surra are due to the same Trypanosoma, but are not conclusive ;
the evidence points to the possibility of their being due to different organisms.
18. A number of papers on the subject of Tropical diseases have been
published during the year. It will be seen that the work done has been
very great and valuable, and the results reflect great credit on Dr. Lingard
and his Assistants.
No. 1834, dated Simla, the 16th October 1907.
From—J. WILSON, Esq., C.S.I., I.C.S., Secretary to the Government of India,
DEPARTMENT OF REVENUE AND AGRICULTURE,
To—The Inspector General, Civil Veterinary Department.
I AM directed to return the copy of the report of the Imperial Bacterio-
logist for the year 1906-07 received with your letter No. 215—189 R. & A.,
dated the 6th ultimo.
2. The report, which is the last that will be submitted by Dr. Lingard,
is a record of another year's good work at the Laboratory. The increasing
success of the system of inoculation in combating outbreaks of rinderpest,
the best evidence of which is to be found in the growing popularity of the
system in some parts of the country, and the weakening of the prejudices
against it in others, is especially satisfactory, while its actual value to the
country in the preservation of agricultural stock must be very great.
Dr. Lingard retired from the Civil Veterinary Department on the 1st Septem-
ber last, and the Government of India desire to take this opportunity of
placing on record their appreciation of the valuable services rendered by him
to veterinary science in India during the 17 years in which he has held the
office of Imperial Bacteriologist.
