the direction in which the plates are to be read. It is clear that in this 
vase they are to be read from right to left; that is,in a reverse order 
to the paging. 
We turn next to plates 11 and 12 of the same codex. Here, as in 
the preceding illustrations, the series of counters and days are placed 
in two lines, an upper anda lower; however, the numbers in the lower, 
apparently because of the want of space, are not placed in connection 
with the day symbols, but by the side of the larger figures. In each 
section of the lower line are five day symbols; for convenience I have 
placed the names in columns, the top one corresponding with the 
symbol at the left in the plate.

Commencing with Cipactli at the right of the lower line of plate 12, 
we go backward (upward as given in the list above) to Atl, then to 
Ocelotl and pack (up) to Ehecatl, thence to Mazatl, right of lower line, 
plate 11, and so on to Tochtli. We begin the upper line with 4 Ollin, 
at the right of plate 12. Passing over four days we reach Ehecatl; four 
days more bring us to Mazatl, upper line, plate 11; four more to Mal- 
inalli, and four more back to Ollin, thus covering twenty days. The 
Ollin symbol of this series (plate 12) is immediately under the blue sit- 
ting figure; Mazatl, or Deer (plate 9, upper line) is represented by the 
foot or lower portion of the leg of a deer. This proves that the read- 
ing is from right to left and from the bottom upward as in the preced- 
ing plates. It also enables us to determine positively the unusual 
Mazatl symbol. 
The days in the lower line are arranged five to a section, after 
the manner explained in a previous paper.’ Commencing with 
Cipactli, at the right (bottom in our list) of plate 12, we count or pass 
over twelve days and reach Ocelotl, the day at the right (bottom) of 
the le ent series of the same plate; twelve more bring us to Mazatl, right
