The photographs relating to the discovery of the statue of Chac-Mool are found in a series of twelve pictures, herewith presented in the plates which follow. It is upon this discovery, as will be seen from his _Mexican Memorial_, that Dr. Le Plongeon has relied more than upon any other result of his labors, for fame and remuneration. The statue was exhumed, according to the account in the _Mexican Memorial_, in consequence of interpretations of certain mural tablets and hieroglyphics, which the discoverer and his able coadjutor, Mrs. Le Plongeon, found in the building shown in the pictures 1 and 2 on the opposite page, upon the south-east wall of the so-called Gymnasium,[58-*] which Dr. Le Plongeon says was erected by the queen of Itza, to the memory of Chac-Mool, her husband. As may be seen from a careful inspection of the picture, the stone building is decorated by a belt of tigers, with an ornament separating them, which may have been the “totem.” [Illustration: _Decorated Building at Chichen-Itza, Yucatan, and the external appearance of the place whence the Statue was exhumed by Dr. Augustus Le Plongeon._ DESCRIPTION OF PLATE. 1. Represents the building at the southern extremity of the eastern wall of the so-called Gymnasium described by Stephens--Travels in Yucatan, vol. II., page 308. It is supposed by Dr. Le Plongeon to have been a monument to the chieftain Chac-Mool. 2. This picture shows the upper portion of the same edifice, in which were found “the mural paintings, bas-reliefs and other signs,” which gave a clue to the discovery of the statue. 3. Shows probably the locality where the statue was excavated. The same sculptured slabs that appear in picture 8 in the foreground on the right, are seen resting against a mound, in their supposed original position, and serve to indicate the identity of the localities. In the rear of the slabs is probably the heap of stones forming the pedestal for the stone figure of a tiger spoken of in the “_Mexican Memorial_.” 4. This is probably another view in the immediate neighborhood. Among the scattered debris is the sculptured head of a serpent, with open jaws. 5. Represents the sculptured slabs, which are seen also in pictures 3, 6 and 8. They are of unequal width, but the length and thickness was probably the same in each. 6. Another view of the sculptured slabs. The first shows a bird of prey; this is apparently a tiger. Both of them hold in their grasp objects of a similar character. NOTE. Several of these pictures are described in the _Mexican Memorial_, but are there differently numbered.]
