Bulletin No. 48. Page 2., Lawyer's brief includes the following in connection with a refusal to register the trade mark, Limestone Brand, a carthartic medicine, because the medicine did not contain limestone: "Ivory is a good trademark for soap and is not made of ivory. Gold Dust washing powder is not made of gold. There is no bull in Bull Durham. Pearline contains no pearls, and White Rock is water. There is no cream in Cream of Tartar, in cold cream or in chocolate, no milk in magnesia, in milkweed or in the cocoanut. These are all as remote from the cow as the cowslip. There is no grape in grapefruit, or bread in breadfruit. A pineapple is neither pine nor apple; a prickly pear is not a pear; an alligator pear is neither a pear nor an alligator, and a sugar plum is not a plum. Apple butter is not butter. All the butter is taken out of buttermilk, and there is none in butternuts, nor in buttercups, and the flies in the dairy are not butterflies."
