?9 part performed after the decline of the outbreaks in the villages of the inocu- lated persons, they afforded no statistical evidence of the efficiency of inocu- lation. But they tended to familiarise the minds of the people with the opera- tion and to dispel the mistrust and fear with which it is usually looked upon by those who have had no previous experience òf it. As a matter of fact what was done in 1901 produced a considerable demand for inoculation in the next plague season, 1901-02. No attempt, however, was made in that season to press it upon the people, and all that was done was to inocu- late as far as possible those who desired it. A desire for it was usually ex- pressed only by the people of infected places at the time when plague there was at its height, but during the climax of the outbreaks the demand was so keen that the limited Medical staff which was on plague duty found it impossible in certain districts to inoculate all who wished to be done. It is reported that many persons performed considerable journeys and underwent considerable personal inconvenience in order to present themselves for the operation. The total number of inoculations done between the 1st of October 1901 and the 31st August 1902 was 211,503, chiefly in February (26,015), March (41,590), April (47,612), and May (35,721). The numbers inoculated in the districts in wnich most operations were done are given in the following statement :- District. 1901-02. MONTHS IN WHICH MOST INOCULATIONS WERE DONE.

Unfortunately it was found impossible accurately to follow up the results of the operations of 1901-02. The press of work was very great and the staff that had to cope with it was insufficient, while in some cases the severity of the outbreaks disorganised the reporting agency. In Ferozepore the inoculations were mainly done after plague had begun to decline, and hence statistics of its protective value cannot be obtained. In many districts no statistical statement of the results is forthcoming. In Ambala, Hoshiárpur and Siálkot the local officers were able to collect statistics which can be accepted as fairly correct, and these evidence the value of the operations. The results are apparently unfavourable in Ludhiána only. The figures collected for this district give a higher case mortality among the inoculated than among the uninoculated The district, however, was one in which the reporting agency was thoroughly disorganised, and there is reason to believe that the statistics are altogether incorrect. The results were undoubtedly protective in many indivi- dual cases and inoculations came well out of the test to which they were sub- jected, which was a severe one, since the operations were performed only on
