No returns have been as yet received from these gardens, further than a communication that, since the date of the inoculation, there occurred 2 cases with 1 death in Burnie Braes, 3 cases with 1 death in Loobachera, 4 cases with 2 deaths in Kalainchera and 2 cases with 1 d^ath in Sandura, all in uninoculated coolies. Of these 2:ardens, in Burnie Braes and in Kalainchera a larffe proportion of the population had been inoculated (449 and 145, respectively, makincr \ io \ of the whole population ) ; in the two other gardens, the proportion of inoculated was from 1^ to \ of the total. 13. Summarising the observations made on the gardens, on coolies inoculated once, that is, before the second inoculation was applied, the results are as follows :— Total of uninoculated on all the affected gardens'^— Percentage.

To this information I have to add that contained in two letters addressed to me recently by two influential mercantile firms in Calcutta, in whose gardens inoculations have been carried out. They are additional observations to those already mentioned and improve the results given by Mons. Haffkine to a considerable extent:— To Health Officer, We have pleasure in communicating the under-noted extract from a letter from Mr. H.
