Annandale 1 remarks regarding the Calcutta tanks—" The best of the tanks from the sponge-collector's point of view so far as I have been able to discover is the one in the compound of the Indian Museum. [...] The small fish and prawns had by this time retreated from the margin of the tank and the moluscs were in the process of so doing ; there were far fewer round the margin in the shallow water than there had been on the 19th. [...] A microscopic examination of the gills of both fish and prawns within a few minutes of their removal from the tank in the laboratory of the Zoological Survey of India in the Indian Museum showed no trace of any condition that could be attributed to a prolific growth of bacteria. [...] On the day of the epidemic but later in the day and after the cause of the mortaity had apparently disappeared the Health Officer to the Corporation of Calcutta sent one of his analysts who took two samples of the water. [...] The result of the examination of the water by the Chemical Examiner to the Government of Bengal shows that the mortality was not due to the introduction either deliberate or accidental of any poison and it appears from the data given above that the change in the water was confined to its gaseous content.
