§ MR. WEIRI beg to ask the Secretary for Scotland, having regard to the fact that the medical officers for the nine parishes in Scotland who applied last year for humanised lymph in preference to glycerinated calf lymph based their preference on the assumption that the former lymph was more potent, will he state whether the Local Government Board for Scotland have taken steps to point out to these officers that statistics show the percentage of successful vaccination with glycerinated calf lymph to be distinctly higher than the percentage of successes with humanised lymph?
§ *THE SECRETARY FOR SCOTLAND (Mr. A. GRAHAM MURRAY,) ButeshireI am informed that the reason given by the medical officers referred to for preferring humanised to glycerinated calf lymph was not that the former was more potent, but that it kept its potency for a longer period. The Local Government Board for Scotland see no reason for directing the attention of these officers to the statistics of relative success of the two varieties of lymph.
