§ Mr. MACLEANasked the Home Secretary the number of experiments in vivi- 245W section carried on during 1927, performed with anæsthetics and without anæsthetics, respectively?
§ Sir W. JOYNSON-HICKSThere were 13,871 experiments with anæsthetics and 279,431 without anæsthetics. The latter class of experiments were mostly inoculations and feeding experiments and in no case was an operative procedure more severe than simple inoculation allowed without an anæsthetic.
§ Mr. MACLEANasked the Home Secretary the number of experiments in vivisection performed on animals which were kept alive for observation and/or further experiment; and how many dogs and cats were included in this class of experiment?
§ Sir W. JOYNSON-HICKSI presume that the hon. Member refers to experiments under Certificate B. (i.e., where the experimenter is relieved from the obligation to kill the animal before it recovers from the anæsthetic). There were 7,647 such experiments in 1927, of which 583 were on cats and dogs.
§ Mr. MACLEANasked the Home Secretary the number of places registered in 1927 in Great Britain for conducting experiments in vivisection, and the number of persons licensed to conduct such experiments.
§ Sir W. JOYNSON-HICKSThere were 253 registered places and 1,230 licensed persons.
