Extract
In connection with the cause of the unusual mortality of oysters reported on the oyster beds in the Thames Estuary in 1920 (see Min. Agric. and Fisheries Report, Fishery Investigations II, 6, Nos. 3 and 4, 1923–24, London), it is of interest to compare the simultaneous effects of known solutions of T.N.T. (Trinitrotoluene) in sea-water on both Portuguese and native oysters. In order to obtain some information on this problem the experiments described in the following pages have been carried out at the request of the Fisheries Department of the Ministry of Agriculture and Fisheries and with the help of the Government Chemist and his assistants.

* One brood Portuguese and one brood native included.
† On October 3rd when the maximum number of oysters was found gaping or dead, the pH was found to be 8.00 (courteously determined by Mr. C. F. A. Pantin).
‡ The salinity of the tank water is ordinarily high, and rose in the experimental tanks (5 and 8) to 36.92% which is a very high figure and abnormal in our seas.
* The tanks could not be examined on Oct. 2nd.
