Gas —with Warning
An effort Is being made to produce gas with a special smell, so that, in case of an escape, there shall be adequate warning. Professor Grassberger, manager of the University Institute of Hygiene, Vienna, has been entrusted with the task. A number of experiments have been made which, it Is hoped, will lead to success. Twenty-five chemicals, including camphor and musk, have been tried with a view to waking up persons asleep by some specially penetrating smell. In a laboratory, with doors and windows closed, experiments were made on mice. Only two kinds of gas with a satisfactory smell were found. Experiments are now being made to find a mixture suitable for "perfuming” the gas. The new chemical is being kept secret. During the past few years a very large number of persons used gas for committing suicide. Perhaps the new discovery will make it more difficult for the intending suicide to brace himself to the deed.
