It is impossible to give the figure asked for by the noble Lord. British artificial limbs have reached a high state of perfection and have a worldwide reputation and during the last few years improvements have been mainly in the nature of refinements, which as they have been approved, have been embodied in new limbs. On 23rd May, my right hon. Friend gave the noble Lord up-to-date information about the suction socket limb, which has been undergoing prolonged trial. My right hon. Friend would like to pay a tribute to the limb manufacturers who are unremitting in their search for improvements.
