Cuming, Surgeon Sonera1, P.The United States Public Health Service, Washington, C. Soar Sector Cuming; Tour latter of August 24 and the preliminary plan for ethyl gas investigations were carefully read. It seems to me that the proceedings outlined in the plan are axe silent in every respect. Horarer, does this plan in?o.Ire investigations into the he sards connected with the samf&eture of the ethyl fluid itself as well as the ha sards connected with gas treated with the ethyl fluid? I suppose that the investigations already undertaken along this line will be supplemented by the Service at acme time, although as far as the coffimerelal use of ethyl gas is concerned the plan as outlined should gi7e reliable information.
