"In addition to the contact test, see paragraph 6, the Kanti bullocks received each a subcuatneous injection
of 1 c.c.m. of virulent blood from buffalo 0.1 ; similar material was well rubbed into the nostrils, muzzle and
mouth ; the ingesta of 0. 1 , 0. 2 , and 0. 3 , were strewn on the ground where the bullocks were fed ; the blood of
0. 1 , 0. 2 , and 0. 3 was mixed with water and poured over the straw they ate. I may add that, as the standings
had been purposely left unclean for some time, they had acquired the usual condition found in villages. I
would like to remark that the fall in temperature which occurred on and after the 10th October was coincident
with cyclonic weather (rain and wind) which greatly cooled the
atmosphere.
"It has already been reported that 5 of the 16 Kanti bullocks, under experiment, had been injected at
various times with virulent blood for testing purposes, while 11 had not received any other treatment than the
bile injection in September 1897. A study of the charts does not indicate any striking difference between the
two series.
"The object of investigation was to ascertain if the immunity conferred by the buffalo bile as used in
September 1897 lasted for a year. The result of the experiments is that, although some of the bullocks' tem-
peratures reacted, none of the animals showed any outward symptoms of ill-health, notwithstanding the fact that
the test was very much more stringent than that which animals would be put to in practice.
"These results indicate that bile injection in proper hands may be an effective means of combating Rinder-
pest in Bengal if the people learn to appreciate its value. Unfortunately they are so accustomed to consider
Rinderpest as part of the normal order of things that much apathy will no doubt have to be encountered.
Moreover, it will be necessary to have a specially-trained man, at any rate at first, to do the inoculation, etc.,
and he will have to be paid.
"The serum work is proceeding; much delay occurred through want of material."
APPENDIX J.
RINDERPEST.
Note by Mr. Geo. R. Toomey, of Kanti.
The following is my experience of sending inoculated bullocks among
those of villages infected with Rinderpest:-My brick kiln was situated in the
middle of a village in which cattle were daily dying of Rinderpest. Un-
fortunately I was obliged to get my bricks from there at that time. So I
picked out ten pairs of bullocks that were inoculated in September 1897 and
sent them there regularly from 17th May till 5th June 1898. I kept them
separate from my other cattle during the time they were carting bricks. I
am glad to report that not one of my ten pairs or any of my bullocks which
have been inoculated have caught the infection up to date, though the cattle
in the village I mention were grazing all round the brick kiln and my cattle
mixed with them. I consider the inoculation prevented them getting the
disease.
