§ MR. THOMAS BAYLEY (Derbyshire, Chesterfield)I beg to ask the President if the Local Government Board whether he has noticed the reproduction of a photograph, at page 282 of the Report of his Medical Officer for 1896–7, plate vii., fig. 12, showing that after inoculation with the glycerinated calf lymph which it is proposed to use in future for vaccinating purposes colonies of germs or microbes of other diseases were found to exist, although the lymph had been stored for nine months in undiluted glycerine; and what precautions he proposes to take to secure the destruction of such germs?
§ THE PRESIDENT OF THE LOCAL GOVERNMENT BOARD (Mr. H. CHAPLIN,) Lincolnshire, SleafordThe hon. Member is under a misapprehension is to the plate in question. It does not refer to calf-lymph at all, but to smallpox matter, mixed with undiluted glycerine, which was made the subject of experiment; and there is no necessity for the precautions he suggests to me with regard to the germs in question.
