[40] Similar grafiti were discovered on the wall of a temple at Nakum, in Guatemala. See Tozzer, Preliminary Study of the Prehistoric Ruins of Nakum, Guatemala, p. 160, fig. 48a.

II, No. 1, Researches in the Valley of the Usumatsintla, where on several illustrations rows of similar shells are seen decorating the edges of the garments of the persons represented. [44] It is curious that neither Landa nor Villagutierre mentions this ornamental plugging of the front teeth, as, judging by the number of teeth found, it can not have been of exceptionally rare occurrence. Landa, who describes their ornaments very closely, mentions the filling of the teeth, but not the plugging, which, had it been in vogue at the time of the conquest in Yucatan, he must have heard about or observed. It seems probable that the custom had already become obsolete before the first appearance of the Spaniards in Yucatan. [45] See Spinden, Maya Art, fig. 79. [46] The photographs of the torso and headdress were taken in England and those of the head in British Honduras. Consequently they do not fit together as well as do the originals. [47] It would appear that these thick woven or plaited cotton breastplates were fortified with salt. Landa, op. cit., p. 48: "Y sus rodelas y iacos fuertes de sal y algodon." Ibid. p. 172: "Hazian xacos de algodon colchados y de sal por moler colchada de dos tandas o colchaduras, y estos eran fortissimos." [48] MORLEY, An Introduction to the Study of the Maya Hieroglyphs, p. 15. [49] Accounts of the finding of these incense burners and of copal are common in both ancient and modern times. "Hallé en una de las dos Capillas cacao ofrecido, y señal de copal (que es su incienso) de poco tiempo allí quemado, y que lo era de alguna supersticion, ó idolatria recién cometida."--COGOLLUDO, Historia de Yucathan, Bk. IV, Cap. VII, p. 193. "Y los que ivan tenían de costumbre de entrar también en templos derelictos, quando passavan por ellos a orar y quemar copal."--LANDA, op. cit., p. 158. "While searching the upper steps of the pyramid my men found two interesting incense vessels with a head on the rim."--MALER, Researches in the Central Portion of the Usumatsintla Valley, Part 2, p. 136. "In nearly all the houses (speaking of Yaxchilan) I found earthen pots, partly filled with some half-burned resinous substance.... They were in great numbers round the idol in the house I lived in. Some looked much newer than others, and many are in such positions that it was clear that they had been placed there since the partial destruction of the houses."--MAUDSLAY, Explorations in Guatemala, pp. 185-204.
