I intend to close this report with some observations on the criticisms which have been written since the publication of my "Essay on the Decipherment of the Hieratic Writings," as much, regarding the first data, for which we are indebted to Diego de Landa, as that of the method to follow in order to realize new progress in the interpretation of the Katounic texts. I will be permitted, however, before approaching this discussion, to say a word on two leaves of the _Codex Cortesianus_, which not only confirm several of my former lectures, but which furnish us probably a more than ordinarily interesting document relative to the religious history of ancient Yucatan. The two leaves require to be presented synoptically, as I have done in reproducing them on the plate [8 and 9[2]], for it is evident that they form together one single representation. This picture presents four divisions, in the middle of which is seen a representation of the sacred tree; beneath are the figures of two personages seated on the ground and placed facing the katounes, among which the sign of the day _Ik_ is repeated three times on the right side and once with two other signs on the left side. The central image is surrounded by a sort of framing in which have been traced the twenty cyclic characters of the calendar. Some of these characters would not be recognizable if one possessed only the data of Landa, but they are henceforth easy to read, for I have had occasion to determine, after a certain fashion, the value of the greater part of them in a former publication. These characters are traced in the following order, commencing, for example, with Muluc and continuing from left to right: 6, 2, 18, 13, 17, 14, 5, 1, 16, 12, 8, 4, 20, 15, 11, 7, 19, 3, 9, 10. * * * In the four compartments of the Tablet appear the same cyclic signs again in two series. I will not stop to dwell upon them, not having discovered the system of their arrangement. Besides these cyclic signs no other katounes are found on the Tablet, except four groups which have attracted my attention since the beginning of my studies, and which I have presented, not without some hesitation, as serving to note the four cardinal points. I do not consider my first attempt at interpretation as definitely demonstrated, but it seems to me that it acquires by the study of the pages in question of the _Codex Cortesianus_, a new probability of exactitude. These four katounic groups are here in fact arranged in the following manner: [Illustration: FIG. 1.--The four cardinal symbols.]
