THOMAS] NUMERAL SYMBOLS 817 
Iy OrHerR Copices 
in regard to these it may be stated in brief that in the Cortesian 
codex plates 31 to 38 contain frequent repetitions of the ahau symbol, 
used apparently as a counter, ordinary numerals being generally 
attached. These, however have, in addition to the numerals, other 
appendages not seen in the inscriptions (at least not in the same form) 
as, for example, the cross-hatched adjunct seen on plate 34. It is true 
some of the forms given by Goodman show cross-hatching, and of 
these the Cortesian character may be an equivalent. On plate 34 in the 
lower division and elsewhere are symbols (with numerals attached) 
which apparently occupy the place of days and chuens, or of the 
first and second orders of units. However, I am unable to determine 
either their relation to any of the numerous dates on the plate or 
their use. Mr Goodman gives to the cross-hatching in some instances 
the value of 9, but in others he uses it as a multiplier, usually as 
20X20 (see pp. 100, 101 of his work). Possibly he would decide that 
these ahau symbols are simply intended to refer to the beginning of 
the first, third, tenth ahau, etc., according to the number prefixed. 
I am inclined to believe there can be little doubt that they are counters 
with the usual value assigned to the ahau, whatever may be their 
relation to the dates on the plate. 
On plate 35, lower division, and possibly elsewhere, is what appears 
to be a counter in which the chief element is the Cauac character. 
The ordinary chuen symbol occurs quite frequently on the plates 
referred to, but never with more than one set of numerals. Other 
symbols with numerals attached which may possibly be counters are 
found on the same plates, but I have been unable to test the supposi- 
tion. 
In the Troano codex what appear to be ahau symbols are found on 
plates 20 to 23, 31, T* to 10*, and also elsewhere. On the latter two 
plates are also what appear to be katun symbols. In a few instances 
these two symbols have numerals attached. Scattered through the 
codex are quite a number of other symbols with numerals attached, 
which appear to be counters or number glyphs. On the so-called title- 
page of this and the Cortesian codices are quite a number of glyphs 
which I take to be number symbols. Some of these I presume from 
the form to be chuens, but they are in groups usually with numerals 
attached, and as in three instances these numerals are 19, I take 
them to indicate days, and the number of chuen symbols in a 
group to indicate the number of chuens, as the two numbers attached 
to the chuen glyphs in the inscriptions indicate the days and chuens. 
IT am also rather inclined to the belief that on this title-page the 
fourth line of characters from the top denotes ahaus. The red oval 
symbols below with numerals attached are also probably number glyphs,
