§ 86. Major Ramsay
asked the Secretary of State for the Colonies whether every precaution is being taken to prevent the development of races of trypanosomes immune against antricyde, in view of the fact that immune races have developed in the case of previous drugs.
Mr. Creech Jones
Yes. My advisers are very conscious of this possibility. The use of antricyde is being controlled initially by Government Veterinary Departments largely for this reason.
