HAFFKINE'S PREVENTIVE INOCULATIONS AT GYA JAIL. We draw the attention of our readers to Br. Macrae's very full and valuable report on the results of anti-choleraic inoculations in
Gya Jail prevailing. It
a time when an epidemic was will be noted that the observations here made refer mainly to the period of ten days, which
claimed as necessary to produce the protective effect of the inoculations, the first requiring about five days, and the second a similar period.
It has been

It will be observed that during the first eight days there were 12 cases and eight deaths among
inoculated, and eight cases and five deaths the inoculated, and that after this when among the second inoculations had had time to act that no further cases or deaths occurred among the
deaths among the non-inoculated.
