asked the Minister of Health why, in view of the fact that 80 per cent. of deaf aids now manufactued are one-piece aids, he has decided on a two-piece aid for free supply to the deaf under the National Health Service.

The decision has been taken owing to the disproportionate cost involved in using the miniature batteries required for one-piece aids.

In view of the fact that the Government aid is being manufactured on a mass production basis surely it is possible to make a one-piece aid on a cheaper basis?

That is another question. I have said that they will be available when the National Health Service starts on 5th July next year.

asked the Minister of Health what scales of spares and replacements have been allowed for to service the two-piece deaf aid now being manufactured for free supply to the deaf.

The general basis adopted has been an annual replacement rate of 25 per cent., with a higher rate for valves owing to their shorter life.

Can the Minister say why a very much higher rate of replacement was decided upon in the case of his unit than is customary in normal commercial practice?

I understood that British valves are being used in order to save dollars and we could not be sure what the experience with them will turn out to be.
