The result of this second series was that vaseline vaccine was successful in 19 inser-
tions out of 20, or 95.0 per cent.; this is not quite so successful as it was in the former ex-
periments when it was cent. per cent.
The lanoline vaccine made here was successful in 16 insertions out of 20, or 80.0
per cent.; this is not so good as the vaseline, but better than it was last time when it was
78.5 per cent.
The lanoline vaccine from Mysore was successful in only 7 insertions out of 20,
or 35.0 per cent.; this is much worse than it was last time when it was 71.4 per cent.
Vaseline vaccine is seen to be the best of all those experimented with. Vaseline
being softer and melting at a lower temperature penetrates into the scratches more readily
than lanoline which is harder and more like lard in its consistence.
These bottles containing the different mixtures were kept till the month of March,
the lanoline mixture was covered with mould. The vaseline alone remaining unaffected.
It was now decided to begin work on a larger scale with vaseline vaccine. As
soon as arrangements could be made to make the vaseline vaccine in sufficient quantities,
it was to be supplied to all the Vaccinators of this district, and it was agreed that as much
as could be spared should be sent by the writer, through Surgeon-Captain James, the
Deputy Sanitary Commissioner, to the Special Staff Vaccinators who work under him.
To facilitate the inoculation of the buffalo-calves a table was been made ; it was
suggested from one that was seen in use at Berlin by Brigade-Surgeon-Lieutenant-Colonel
Roe. This table has a top fitted with straps to fasten the calf and hinges to enable the
top to be put in a vertical position, while the calf is being strapped to it, and then let down
into a horizontal position. This can be better understood from the accompanying photo-
graphs.
The author also had a glass case made in which the mortar for pounding is placed,
a muslin curtain hanging down on one side through which the arm and hand pass.
This when sterilised with corrosive sublimate solution, prevents dust and the
breath of the operator coming m contact with the vesicles while being pounded up and
mixed with vaseline. In this case the prepared vaccine is also put into the small glass
tubes and corked up. This case and the glass tubes with the sections of bamboo in which
they are packed for transmission by post can be seen in the accompanying photograph.
The author has had a lancet made for making scratches for use with vaseline vaccine.
The worn-out blade of an ordinary bleeding lancet is cut across and filed into four points.
The two tortoise shell handles are replaced by two pieces of steel, each 1½ inches long
and ¼ inch broad at the rounded extremity, just large enough to reach the bottom of the tube
in which the vaseline vaccine is distributed. The blade and handle can be sterilised in a
spirit-lamp flame, while the other handle is held. The sterilised handle, can then be
used as a spatula to rub the vaccine into the scratches. The cost of the lancet is six (6)
annas.
