the results as when conducted at Bareilly. Further, researches with regard to
diseases in large animals, as for instance, elephants, camels can only be carried
on, under plains conditions, in a Laboratory like that at Bareilly. In addition,
when a succession of tests upon plains animals have to be conducted, such
animals of different ages as are required are easily obtainable at short notice
and at a less cost at Bareilly than at Muktesar.
13. Staff and establishment.—During the past year the services of a Hospital
Assistant have been secured and the dispensary attached to the Laboratory is in
working order. To show the great want of such an institute it is only necessary
to state that the average monthly attendances during the month of May last
amounted to 603 cases.
I take this opportunity of placing on record my warmest appreciation of
the support I have invariably received from all the members of my staff and
establishment.
With regard to the subordinate establishment, I would like to specially
mention the names of Mr. Max Kriebel. European Head Laboratory Assistant
and Babu Krishna Nand, Head Clerk.
SECTION II.
Research.
14. As during the last year, the work to be carried out within the year
under review was proposed on the following diseases—
(i) Rinderpest.
(ii) Piroplasmosis and Trypanosomiasis.
(iii) Surra.
(iv) Anthrax.
(v) Hæmorrhagic Septicæmia.
(vi) Charbon Symptomatique.
(vii) Dourine.
Rinderpest.
15. Serum exposed during two hot seasons in the plains.- Serum
No. XXIV despatched from Muktesar to Karachi (Sind) in March 1905, and
allowed to remain in that station for a period of nearly two years, when
returned to the Laboratory for the purpose of retesting was found to have lost
55 to 60 per cent. of its protective power.
16. Serum prepared during the excessive cold of the winter 1906-1907.—
Contrary to expectation, it was observed that anti-rinderpest serum prepared
during the cold season of the year, was 54 times weaker than that prepared
during other seasons of the year. This was probably in part due to the poor
condition of the hill animals, on their arrival at Muktesar.
It has been found more satisfactory to undertake the standardizing of
anti-rinderpest serum on hill cattle during the winter months, at a station in
the plains, as the great bulk of serum prepared is for use on plains cattle, which
are not exposed to the excessive cold encountered in the mountaneous districts.
17. Insusceptibility of the Indian Elephant to Rinderpest.—In order
to determine whether elephants are susceptible to Rinderpest and suffer
from the disease during outbreaks amongst cattle and other animals a female
elephant, in perfect health and condition, normal temperature ranging between
36 and 37.3° C., was subcutaneously inoculated with 500 c.c. of virulent
defibrinated blood obtained from a hill bull the subject of well marked rinder-
pest. A diffused swelling occurred at the seat of inoculation, which had
decreased in extent after a period of twenty-four hours and only a slight
thickening of the skin was perceptible a few days later. No rise in tempera-
ture was recorded, and the animal never exhibited any untoward symptom of
any kind, during the following twenty-three days.
18 Spirochætosis in plains and hill cattle, affected with Rinderpest.—This
form of disease not previously recognized in this country, was met with, during
the year under review, in hill and plains cattle. At a previous date (1894),
