This clue, if followed up, appears to furnish an explanation of some other characters in which the little circle and loops are found. For example, the character shown in plate LXV, 44 (Dres. 2 (45)b and c), apparently refers to the act of sewing or stitching indicated by the pictures below the text. As the circle and loops form an important part of the character, it is probable that _c_ or _ch_ is the chief or prominent element of the word. It is possible therefore, that _chuyah_, "to sew," or some derivative thereof, would be a proper rendering. The glyph shown in plate LXV, 45, from. Tro. 11*c is a duplication of LXV, 44. As the appendix, as shown elsewhere, probably has _ah_, _ha_, or _hal_ as its phonetic equivalent, we have, as the elements of the word represented by the whole glyph (omitting the prefix), _ch'-ch'ah_. As _choch_ (_chochah_), Perez, and _chooch_ (_choochah_), Henderson, signify "to loosen, untie, disunite, detach," this may be the true interpretation of the symbol. The presence of the eye in a symbol appears, as a rule, to have no special significance, as is shown by its presence sometimes in the symbols for the days _chicchan_ and _oc_. It is worthy of note that Dr Seler introduces into his manik series the character above shown as having some relation to and being possibly a variation of that symbol. Before attempting to trace the symbol of the day in its combinations with other characters, with a view of ascertaining its original signification, reference will be made to the signification of the day names in the different calendars. The signification of the Nahuatl word _atl_ is water; the Zapotec names are also words for water. _Tohil_ was the name of the principal Quiche deity, and appears to have been the god of thunder and rain, and, as Seler presumes, was the representative in these nations of the Maya Chac and Mexican Tlaloc. According to Brasseur, _toh_ signifies "a heavy or sudden shower" or "thunder shower." Drs Seler and Brinton both derive the Maya and Tzental names from the radical _mul_ or _mol_, "to join together, collect, heap up," and suppose it refers to the gathering together of the waters (that is, the clouds) in the heavens. This brings the signification of these two names into harmony with that of the names of the other calendars, and is probably a correct interpretation. There are but few places where the symbol of this day is found in connection with other characters that I have been able to interpret entirely satisfactorily.
