Ward Hunt, Arthur v. Sussfield — Opinion of the Court
“ Steel may or may not form a part of the spectacles. The article will be as perfect without steel as with it. On the other hand, the terms 'pebbles for spectacles and all manufactures of which glass shall be a component material,' naturally connects the glass manufacture with the spectacles. There could be no spectacles without them. The colorless crystals in spectacles, termed pebbles, and the manufactures of glass used in spectacles, embrace the same idea ”
