§ * MR. CORRIE GRANT
I beg to ask the Secretary to the Local Government Board whether he can state the original sources of the vaccine lymph supplied by the Government; is any derived from the inoculation of smallpox on animals; whether a pure culture of the organism of vaccinia could be supplied in place of lymph; whether the strength of the virus can be standardised so as to measure the dose administered; whether the Government guarantee the purity and innocuity of the lymph they supply; and whether the Government will take steps to secure the control and supervision of all lymph used in this country.
§ THE PRESIDENT OF THE LOCAL GOVERNMENT BOARD (MR. WALTER LONG,) Bristol, S.
The lymph supplied by the Government is derived from calves which have been vaccinated with lymph from other calves, and is not obtained by inoculating animals with smallpox. The reply to the third and fourth questions is in the negative. The Government give no guarantee, but they use every effort to secure that their lymph shall be free from undesirable organisms. As at present advised, I do not propose to ask for power to control the lymph supplied from other sources.
