§ Mr. BENTHAMasked the President of the Local Government Board whether he is aware that in his Report for the year 1911–12 Dr. F. R. Blaxall, bacteriologist for glycerinated calf lymph at the Government lymph establishment, announces the use of 732 calves as vaccinifers for the cultivation of lymph, compared with only 417 the previous year; is he aware that in the year 1911–12 only 444,878 vaccinations and revaccinations with lymph supplied by the Board were carried out, compared with a total of 484,024 such operations the previous year; and will he explain why it was necessary to employ this increased number of calves in 1911–12, as compared with the previous year or the general average, seeing that there was so substantial a diminution in the amount of lymph used?
§ Mr. BURNSDuring the year 1912 the Local Government Board took occasion to add to their reserve of lymph, and the additional number, of calves were used for this purpose.
