_b._ Both these letters are supposed to represent a path or way bearing the marks of foot prints, indicated by the small figures inside the circle. _c._ This letter should probably be pronounced _ka_ (_a_ as in mate), and is imagined to represent a mouth displaying sharp teeth. _ca._ This sign is explained as the jaw of an animal thickly set with teeth; but a careful examination of its variations leads to the belief that it is a representation of the eye lashes. (See the _Etudes sur le Manuscrit Troano_, p. 55.) _cu._ This has not been identified. _t._ As there is no d in Maya this character stands for both t and d. It signifies space, the four marks leading towards the center representing the four cardinal points, and the phonetic base being the Maya, preposition _ti_, in, toward, at, in space. _e._ Probably a front view of the human face, surmounted by the hair, the dots marking the eyes, nose and mouth. _k._ Nos. 12 and 13, variations of the same, represent a joint of bamboo. No. 14 is the guttural h, pronounced _ha_, which word in Maya means water. The figure represents a stream flowing around some objects. _i._ This letter stems formed after the analogy of c, but no satisfactory analysis has yet been offered. _k, ku._ The k is beyond doubt derived from a head seen in profile. The upper figure within the circle is the closed eye with its lashes (compare No. 8); that below on the right is the ear (compare No. 28); that on the left the mouth. (See the variations in the _Etudes sur le Manuscrit Troano_, p. 55.) The ku is supposed to be a drawing of the sacred "medicine bag." _l._ Neither of these has been resolved. _m._ This also, is the figure of a head. It is distinguished from the k by the eye being open, from the p by the absence of dots around the mouth. _n._ Possibly the figure of a serpent. _o._ Variations of the same, of uncertain origin. _p, pp._ Again the face in profile. _x._ The first figure is easily recognised as the human hand, the second as a face in profile, emitting breath from the mouth. _u._ The first sign represents the ear, the second is of uncertain derivation. _z._ This seems to be a vase of some kind. It is evident that many of these signs have received abbreviated and conventional forms quite remote from their original figures, precisely as we know occurred in the Phenician and derived alphabets. The variations are numerous and puzzling. It will be observed that the basis of most of them is a head seen in front or in profile. Bearing this in mind, and fixing definitely the differential marks, which alone were deemed of importance by the native artists, we could venture with considerable confidence on the interpretation of manuscripts and inscriptions, did we not meet with very serious obstacles in other directions.
