	tion it very closely resembles a gigantic adze of granite, 57 centi­meters long and 34 centimeters wide, mentioned by A. Cha-vero,1 and it has almost a counterpart in the green aventu-rine quartz adze now forming part of the Christy Collec­tion at the British Museum, and formerly in the possession of Percy Doyle of the British Diplomatic Service, differing from these two objects, however, in having no ornamenta­tion on the forehead, and in having four dull markings on each ear, one under each eye, and one near each hand, which seem­ingly could have served no other purpose than to hold thin plates or films of gold, which the polished surfaces would not do. If this was so, no trace of the gold can now be seen. From all ap­pearances, this adze was shaped from a boulder, since weathered surfaces, such as appear on all sides of it, would be found only on an exposed fragment. The lapidarian work on this piece is probably equal to anything that has been found, and the polish is as fine as that of modern times. One point of interest, which should not be lost sight of, is the removal of a portion which has weighed fully two pounds. Why was this ? Similar remov­als and divisions have been mentioned. On April 27, 1881, in a paper read before the American Antiquarian Society, Philip J. J. Valentini described two carved jadeites which showed similar treatment. One was the Humboldt celt, a votive adze presented to Humboldt by Del Rio in 1803, and the other, the so-called Leyden plate, which was found by S. A. von Braam near St. Felipe, in Honduras, near the borders of Guatemala, and given by him to the Leyden Museum. Both of these objects are 9 inches in length and 3 1/4 inches in breadth, the former having a thickness of 1 2/5 inches and the latter 1/5 of an inch. From the fact that the two, if placed together, face to face, have exactly the same outline, it is highly probable that they were originally part of one and the same celt, and it is quite possible the remaining parts may yet be found. In 1886, Professor Frederick W. Putnam exhibited before the same Society a remarkable series of Nica-raguan and Costa Rican jadeites, which were all ornaments, and showed that they had been made by cutting celts which had been perforated by one or two drilled holes, into halves, thirds, and ' Mexico A traves de Los Siglos, Mexico, 1886, p. 64.
