means of Black Legoid vaccination and another 46 animals were done in Chittoor
district. With the means at our disposal up to the present, in order to protect
animals against this disease, it has been essential that animals treated should be so
done a month before the recurring annual outbreak, i.e., before the disease actually
exists, because inoculation must not be carried out in the presence of the disease. It
has been found almost impossible to get the ryots to submit their young stock for this
protective vaccination before an expected outbreak in black-quarter areas and so
preventive measures against this disease have not made much headway. The Director
of the Bacteriological Laboratory, Muktesar, is now manufacturing two new substances,
viz., a germ free filtrate and an anti-serum for inoculations against this disease. The
latter may safely be used during an outbreak and although it gives immunity for
only a fortnight, that is sufficiently long to prevent infection during the time the
animals remain on the infected land and will thus be of use in preventing deaths.
During an outbreak, therefore, the ryots will more readily accept inoculation of their
animals,
30. Foot-and-mouth disease.--The mortality under this head shows considerable
decrease, the number being 1,278 against 2,403 in the preceding year. Vizagapatam
and Ganjām districts accounted for 241 and 174 deaths respectively. The staff
received 285 reports and attended 256 of them. Last year 716 reports were received
and 560 were attended.
31. Glanders and Epizootic Lymphangitis.—No case of either of these diseases
was detected.
32. Infectious Lymphangitis of cattle.—Eighteen cases of this disease were con
firmed microscopically.
33. Trypanosomiasis.—This was detected in 3 ponies, 2 bullocks and 10 buffa
loes. The ponies were destroyed under the Glanders and Farcy Act No. XIII of
J 899 and compensation was paid to the owners. All the buffaloes affected belonged
to Ketti village in the Nilgiris and of the 10 attacks, 8 proved fatal.
34. Piroplusmosis.—This disease was confirmed in 14 cases—7 cattle and
dogs.
35. Kumn.—Thirteen cases were diagnosed by the staff during the year.
36. Pleuro-pneumonia.--Two reports of outbreak amongst sheep in Ganjām
district were received and attended. As usual there was an outbreak amongst lambs
at the Government Agricultural Farm at Hagari, but the attacks and deaths were not
so severe as in previous years. The Director of the Muktesar Laboratory diagnosed
the disease to be Pleuro pneumonia Contagiosa but it is still being investigated
by him.
37. Sheep-pox.—This disease was prevailing in Tirukkōyilūr, Srīvilliputtūr and
Harpanahalli taluks. Ten reports were received and attended.
38. Spirochœtosis.--This disease was prevalent among fowls in Bezwada.
89. Rabies.—During the year model by-laws under the Madras District Munici-
palities Act, 1920, were issued by Government for the prevention of rabies.
The brains of 77 dogs and one other domestic animal sent by the staff to the
Pasteur institute, Coonoer, were declared to be rabid. Confirmation was considered
unnecessary in the case of other 52 dogs and 11 other domestic animals. Ten
animals were treated with anti-rabic vaccine at the Veterinary hospital, Calicut.
IV.—MISCELLANEOUS
WORK.
40. Forest Department.—During the year certain suggestions for the proper
conduct of work by the Veterinary officers employed in the Forest Department were
made to the Chief Conservator of Forests, and have been adopted. The Veterinary
Assistant Surgeons at Puttur, Wynad and Pollachi attended on the sick animals
belonging to the Forest Department when called on to do so by the officers of that
department.
41. Criminal.--The staff of this department held 72 post-mortem examinations
on animals suspected of criminal poisoning and 172 animals were examined for mali-
cious injury. The Chemical Examiner dealt with the viscera of 63 animals of which
53 were sent by the staff of this department. Poison was detected in 14 cases. The
