REPORT OF THE KING INSTITUTE, GUINDY.

16. In an enclosure to the Report for 1913-14 Major Patton, I.M.S., found
that better results were obtained on calves if the pulp were stored in the raw
state and only ground and mixed as required. An attempt was made on a large
scale to see if this held good and could be applied to children. It must be
remembered that the conditions could not be made exactly parallel. With
calves the seed lymph was ground, mixed and used. With children the lymph
was ground, mixed and issued ; but the period of use would vary with the
distance of destination, and the habits of the vaccinator. Every alternate batch
of vaccine was stored and ground and mixed as required for issue, while the
remaining half was ground, mixed, and stored till required for issue. Half the
issue for each day was made up of each of these two kinds of paste. The results
up to the end of March were distinctly against the new procedure. 82,828 cases
done with paste made in the revised method were reported on and showed a success
rate of 85.8 per cent.; whereas 88.71 per cent. out of 88,407 cases done with
standard paste were reported as successful. Both these figures are disappointingly
low, but returns of 170,002 cases done with stored standard lymph received
contemporaneously, show a success rate of 86.18 per cent. For some reason
the cold weather of 1914-15 seems to have been unfavourable to vaccinators' work.
Considering the copious rains and that the calves had fair grazing right up till the
end of March the lymph should have been better than usual, but, if so, the
vaccinators do not appear to have been able to profit by it. The yield per calf
was certainly larger than in the previous year and in a special series of calves,
the results from which are given below, the average yield during the latter half
of March and the whole of April was nearly as great as the maximum yield
for the corresponding period of 1914.

Table XI shows the maximum and minimum yield of any calf and the
average yield per calf for each of the months of the year. The maxima, with two
exceptions, are all greatly in excess this year and the minima run slightly higher too.
