§ Sir G. GREENWOODasked the Undersecretary of State for War whether he is 51W aware that the Trench Warfare Committee, who are charged with the duty of investigating the various proposed remedies for patients who have been gassed, were provided in December last with a machine for ozone treatment; whether they were requested to make trial of this treatment, on the ground that it has been found quickly to bring relief to sufferers in these cases; whether, nevertheless, they had not up to the end of last month even made trial of this remedy; whether any trial of it has been made by them since that date; and, if so, when and were was such trial or trials made, and what was the result?
§ Mr. MACPHERSONI presume my hon. Friend is referring to the "Quain" ozone producer. I am informed that a description of this was forwarded to the Chemical Warfare Medical Committee by the Controller of Chemical Warfare in February last. The Committee duly considered the matter, and reported that they were of opinion that it would be highly injurious to employ ozone in the treatment of gassed cases. The Committee felt justified in forming this opinion without any further investigation.
