§ MR. CORRIE GRANT
I beg to ask the President of the Local Government Board whether the lymph obtained by Dr. Copeman from the inoculation of smallpox on monkeys has been used in general practice for vaccination; and, if so, to what extent; and have the parents and the medical men been aware of its origin.
§ MR. WALTER LONG
All the lymph obtained in the manner referred to in the Question was passed through calves and properly glycerinated before it was used for the vaccination of human beings. I understand that the medical men using the lymph thus derived were made aware of the circumstances connected with it, but I cannot say whether the parents knew them. I am informed, however, that the amount manufactured was but small, and that whatever remained in stock was destroyed nearly two years ago.
