GAYA JAIL (1894) 



195 



207 inoculated, and 202 not inoculated. Surgeon- 

 Major Macrae, superintendent of the jail, reports — 



" The inoculations being purely voluntary, no 

 selection of prisoners was possible, but all classes of 

 the jail were represented — male and female, old 

 and young, habituals and less frequent offenders, 

 strong and weakly, convalescent and even hospital 

 patients sent their representatives ; no difference of 

 any kind was made between inoculated and non- 

 inoculated ; they were under absolutely identical 

 conditions as regards food, water, accommodation, 

 etc., in fact in every possible respect." 



Of course, the best results could hardly be 

 obtained, because the cholera was already at work : 

 it took about ten days for the 1894 vaccine to 

 produce its full effect ; and two inoculations were 

 generally made, one five days after the other. This 

 gradual action of the vaccine is well shown in Dr 

 Simpson's table : —
