No. 39, just above it, seems also to be _one_ of the months _Yax_, _Zac_, or _Ceh_, which began on January 12, February 1, and February 21, respectively. Which one of these it corresponds to must be settled by other means than a direct comparison. The signs given by LANDA for these three months all contain the same radical as No. 39, but it is impossible to decide with entire certainty to which it corresponds. It, however, most nearly resembles the sign for _Zac_ (February 1); and it is noteworthy that it was precisely in this month that the greatest feast of TLALOC took place,[244-*] and its presence in this tablet, which relates to _Tlaloc_, is especially interesting. In connection with the counting of time, a reference to the bottom part of the _chiffre_ 3000 of the Palenque cross tablet should be made. This is a _knot_ tied up in a string or scarf; and we know this to have been the method of expressing the expiration and completion of a cycle of years. It occurs just above the symbol 3010, the _chiffre_ for a metal. An examination of the original stone in the National Museum, Washington, which is now in progress, has already convinced me that the methods which I have described in the preceding pages promise other interesting confirmations of the results I have reached. For the time, I must leave the matter in its present state. I think I am justified in my confidence that suitable methods of procedure have been laid down, and that certain important results have already been reached. I do not believe that the conclusions stated will be changed, but I am confident that a rich reward will be found by any competent person who will continue the study of these stones. The proper names now known will serve as points of departure, and it is probable that some research will give us the signs for verbs or adjectives connected with them. It is an immense step to have rid ourselves of the phonetic or alphabetic idea, and to have found the manner in which the Maya mind represented attributes and ideas. Their method was that of all nations at the origin of written language; that is, pure picture-writing. At Copan this is found in its earliest state; at Palenque it was already highly conventionalized. The step from the Palenque character to that used in the Kabah inscription is apparently not greater than the step from the latter to the various manuscripts. An important research would be the application of the methods so ably applied by Dr. ALLEN to tracing the evolution of the latter characters from their earlier forms. In this way it will be possible to extend our present knowledge materially. FOOTNOTES: [225-*] The Life Form in Art, Trans. Amer. Phil. Soc., vol. xv, 1873, p. 325.
