§ Mr. BLACK
asked the Minister of Health whether he will investigate the records which have been kept showing the pedigree of the lymph used at the Hendon Institute; the nature and origin of the strains of lymph now in circulation by the Government; and whether he can supply a chart showing the pedigree of a single strain of lymph now in use?
§ Mr. WHEATLEY
The records show that the lymph now used at the Government Lymph Establishment is derived from calf lymph originaly obtained from Cologne, and the strain has since been carried on, as the hon. Member was informed on 2nd April last, by repeated transference from animal to animal. I fear it is impracticable to chart the pedigree, as suggested, in a form which would be readily understood.
