asked the Secretary of State for War the number of old horses which are unfit for further service and are at present being used for 'the purpose of poison gas research at Hampshire station; and whether the experiments include the cultivation of bacteria for spreading plague?

As my right hon. Friend stated in his reply to similar questions yesterday, of which I am sending the hon. Member a copy, during the period 1921 to 1930 only 25 horses have been used in connection with experiments at Porton. None of the experiments included the cultivation of bacteria for spreading plague.
