Far higher results have been obtained by an application of stronger doses. In the _bustees_ situated round the tanks in Calcutta, where cholera exists in a permanent state, the disease occurred in 36 houses with inoculated people. In each of these houses there was one part of the family inoculated and another not. The observations were continued for 459 days, with the following results:-- During the first period of 5 days, subsequent to the inoculation with first vaccine, cholera occurred in 8 houses. 75 non-inoculated had 5 cases, with 3 deaths. 52 inoculated had 3 cases, with 3 deaths. During the second period of 5 days, subsequent to the second inoculation, cholera occurred in 2 houses. 8 non-inoculated had 2 cases, with 2 deaths. 17 inoculated had no cases. _After the 10 days necessary for the preventive treatment had expired, and up to the 459th day, the disease visited 26 houses._ _263 non-inoculated had 38 cases, with 34 deaths._ _137 inoculated had 1 case, with 1 death, in a child that had not been brought up for the second inoculation."_ 4. _Assam-Burmah Railway_ For a good instance of lives saved even during an outbreak, take the Assam-Burmah Railway coolies:-- _"Three hundred and fifty[30] Khassia Hill coolies had been collected for the survey party of the Assam-Burmah Railway, and put under the escort of a detachment of Goorkhas, when cholera broke out amongst them. The largest part of the coolies immediately submitted to the preventive inoculation, the rest remained uninoculated. The result was that _among the not-inoculated minority there were 34 cases, with 30 deaths; whereas the inoculated had 4 fatal cases_." (Haffkine, 1895, Lecture in London.)_
