CHOLERA 



Lucknow came so early in the work of inocula- 

 tion, that weak vaccines were used in small doses. 

 The cholera, when it broke out, was 4 'of a most 

 malignant type, senior medical officers of long 

 experience in the country stating that such a 

 virulent cholera had not been seen by them for very 

 many years past." More than a year had elapsed 

 between the inoculations and the outbreak of the 

 cholera. It is no wonder that the regiment was not 

 well protected : — 



" The small amount of protection which the 

 inoculations afforded in this case may have depended 

 on the mild effects which the injections produced on 

 the men at the time of the operation in 1893, m 

 comparison with the severity of the epidemic which 

 attacked the regiment. It is recorded in the Luck- 

 now Inoculation Registers that only in two men, 

 out of the 185 inoculated in 1893, a marked febrile 

 reaction was obtained ; in 77 individuals the vac- 

 cinal fever was only slight, while in 66 there was no 

 reaction : an effect which was due to the weakness 

 of the vaccines procurable at that period of work, 

 and to the small doses used. The influence of the 

 vaccines was possibly further reduced, at the time 

 of the epidemic, by a lapse of fourteen to fifteen 

 months." (Haffkine, 1895 Report.) 



3. Gay a Jail. 



On 9th July 1894, an outbreak of cholera 

 occurred in the Gaya jail, and by 18th June there 

 had been 6 cases and 5 deaths. On that day and the 

 next day, 215 prisoners were inoculated. The aver- 

 age number of the prisoners during the outbreak was
