be successful. The small percentage of successful primary vaccinations in this district
was due to the bad work done by the vaccinator of the Mokokchang Sub-division, whose
services were afterwards dispensed with. In the Resolution on the Vaccination
Report of 1895-96 the Chief Commissioner observed that in the Bengal Report for
1894-95 it was stated that many vaccinators in that province excluded unsuccessful
operations from their lists, and he requested the Principal Medical Officer and Sanitary
Commissioner to give this matter his careful consideration, and to record the result of
his enquiries in the next Vaccination Report. A Circular was accordingly sent to all
Civil Surgeons, requesting them to take care that vaccinators did not exclude unsuc-
cessful vaccinations from their lists, and directing them to notice what action they had
taken, with results, in their annual reports. In connection with this Circular all
Civil Surgeons have reported that they were satisfied that all unsuccessful operations
were included in the returns.
