Eustic letters are employed, by which is meant, as the complainants allege, letters in which the nec- essary lines of the same represent the branches or trunks oi trees, unstripped of the bark, the ornamentation consisting of several separate leaves placed at intervais upon the lines of each letter, the lines exhibiting the appearance of the bark of a branch or trunk of a tree, which design is used for orna- menting button^, studs, lockets, and other articles of jewelry. Photographs of the improvement were taken directly from gold sleeve buttons, having leaves upon the lettera in actual relief, as given in the descriptive portion of the specification. Sufficient appears to show that the complainants were jewel- ers, and that for a series of years they had been endeavoring to produce an initial-letter sleeve button which would be more ornamental and better suited for ladies' wear.
