Abstract
IN the course of an extended study of the action of 'physically toxic' substances1 on the grain weevil, Sitophilus granarius, we have determined for this organism the median lethal doses of a number of simple gases such as hydrogen, nitrogen, argon, etc. To attain the required lethal concentrations in these cases, it was necessary to apply the gases at pressures much above atmospheric—for example, up to almost 900 atmospheres in the case of hydrogen.
