HC Deb 18 May 1915 vol 71 cc2119-20
13. Mr. DENMAN

asked whether any convention exists whereby the use of asphyxiating gases, except when emitted from a projectile, is forbidden?

Mr. TENNANT

The actual terms of The Hague Declaration forbid only the use of projectiles the sole object of which is to diffuse asphyxiating or deleterious gases. Obviously the diffusion of the gases was the object of the prohibition rather than the means by which they were diffused.
