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 death in Sandura, all in uninoculated coolies. Of thpse gardens, in Burnie Braes and in Kalainchera a large proportion of the population had been inoculated (449 and 145, respectively, making J to ^ of the whole population) ; in the two other gardens, the proportion of inoculated was from ^ to J of the total. 13.

Weir, Manager of Kalline Tea Estate, Cachar, dated 3rd instant, on subject of Dr. Haffkine’s experiments in inoculation for cholera. Calcutta, 12th July, 1895. Macneill and Co.
