17. Dr. MURRAYasked the President of the Board of Trade if he can explain why Piano and B. I. convex lenses, worked and used in connection with motor and other lamps for illuminating or magnifying purposes, are admitted under the key section of the Safeguarding of Industries Act without being liable for duty, whilst at the same time a duty is levied on ordinary low-grade lenses, illuminating or magnifying, used for spectacles; and can he explain on what standard or definition these two decisions are based?
§ Mr. BALDWINAll types of lenses which have worked surfaces, or are made of optical glass, are liable to duty under Part I of the Safeguarding of Industries Act, irrespective of the use to which they are to be put. I am not aware that any lenses to which either of these descriptions is applicable have been admitted free of duty.
