HC Deb 25 March 1913 vol 50 cc1487-8W

asked the President of the Local Government Board whether his attention has been called to a Memorandum on the manufacture of glycerinated calf lymph, by Captain W. A. Justice, of the Indian Medical Service, in Progress of Sanitary Measures in India (Cd. 6538), describing visits to the vaccine institutes at Hong Kong, Tokio, and the depôt at Hendon; whether he sanctions for use as the best stock lymph that which is derivable by the cultivation of smallpox virus through four to five calves and continued without admixture; whether small-pox virus is now in use at the Hendon depôt for the purpose of propagating lymph supplies or setting up any fresh strain of lymph required; and whether bull calves are preferred at Hendon be- cause the lymph collected from the surface of the scrotum is of greater activity than other lymph?


I am aware of the Memorandum referred to. As regards the source of lymph used at the Government lymph establishment, the usual method of renewing lymph is by vaccinating calves with vaccine lymph obtained from children, but in some instances the lymph has been obtained from abroad, and in such cases it would usually not be practicable to give its original sources. I may, however, state that in no case is lymph used at the establishment unless it has been passed through a series of calves. The answer to the last two parts of the question is in the negative.
