As my right hon. Friend pointed out in his reply of 24th May to the noble Lord, we naturally wish to issue the limb generally only when we are satisfied that every possible improvement has been made. We have now a further 100 patients fitted with the limb for trial. That makes 150 patients now wearing the suction socket limb on trial. Production is a much slower job than the production of the ordinary limb. We hesitate to impede the production of ordinary limbs too much until we are satisfied that the suction socket limb will be really satisfactory.
