Tempting death daily is the lot of a few daring men in a London laboratory, where a steel-walled chamber containing an appreciable quantity of real poison gas is reported in use to test the air-purifying canisters of military gas masks.
Masked experimenters sit outside the deadly chamber, and breathe through hoses that terminate in the canisters within. A white-coated physician stands near to render first aid, in case the poison-absorbing chemicals should fail to function. Only in this way can new types of equipment be tested.
