making one outward and two inward bends or loops 

 at each corner, as shown in fig. 1. 



In this fisure the dots correspond with those in the 

 plate; the circle, with the day-symbols. The numbers

Starting with 1 Cauac (No. 1) on the right side, 

 and running upward toward the top, along the 

 row of dots next the right-hand margin, we reach 

 13 Chuen (No. 2). Just above this is 1 Eb (No. 

 3). Running inward toward the centre, along 

 the row of dots, we reach 13 Kan (No. 4). Then 

 passing upward, we come to 1 Chicchan (No. 

 5); then outward along the row of dots, toward 

 the outer corner, to 13 Caban (No. 6); thence 

 to the left to 1 Ezanab (No. 7); then inward to 

 13 Oc (No. 8); then to the left to 1 Chuen (No. 

 9); then outward to 13 Akbal (No. 10); and so 

 on around toward the left. 



The number of the day is usually indicated 

 by a numeral symbol, — one dot for I, and two 

 short lines and three dots for 13. 



By commencing with Cauac, and writing the twenty 

 Maya days in succession, repeating them in the same 

 order, numbering them from 1 to 13, and 1 to 13 

 again, or by referring to table V. of Professor Thomas's 

 Study iif the manuscript Troano (fig. 11), the reader 

 will find that the days numbered 1 of the looped 



line (as 1 Cauac, 1 Eb, etc.) are always the first 

 days of the Maya week, and those numbered 13 

 (as 13 Chuen, 13 Kan, etc.) are always thelastdays 

 of the week. 



The Cauac years alone have been referred to; 

 but this calendar is made to answer equally as 

 well for the Kan, Muluc, and Ix years. For the 

 Kan years we begin with 1 Kan "(No. 11) in the 

 top row; for the Muluc years, with 1 Muluc (No. 

 21) ii^ the row next to the left margin; and, for 

 the Ix year, with 1 Ix (No. 31) in the bottom 

 row. 



The proof of Professor Thomas's interpretation 

 of this part of the ' Cortesian plate ' seems to be 

 conclusive. 



The signification of plate 44 of the Fejervary 

 Codex he claims to be substantially the same as 

 the other; and that the outer looped line shown 

 in our fig. 2 is constructed on precisely the same 

 plan, and for the same purpose ; the only difference 

 being, that here only the first day of the week is 

 ;iven, and that the days are Mexican instead of 



The twenty circles at the corners and loops con- 

 taining numbers indicate and replace Mexican 

 day-symbols, as shown in the following list : — 



1 Cipactli. 



2 Ocelotl. 



3 Mazatl. 



4 Xochitl. 



5 Acatl. 



6 Miquiztli. 



7 Quiahuitl. 



8 Malinalli. 



9 Coatl. 



10 Tecpatl. 



11 Ozomatli. 



12 Cuetzpalin. 



13 Ollin. 



14 Itzcuintli. 



15 Gain. 



16 Cozcaquauhtli. 



17 Atl. 



IS Ehecatl. 



19 Quauhtli. 



20 Tochtli. 



The four in the larger circle, italicized in the list, 

 are the four year-bearers or year-names. 



By making a list of Mexican days in succession, 

 beginning with Cipactli, and numbering from 1 to 

 13 as before, and following the line in the order 



Fig. 2. — Scheme of the Pejeevakt plate. 



of numbering, as shown in fig. 2 (around to the 

 left), we find that each day is the first of a Mexican 

 week. 



Mr. Thomas also gives interpretations of the outer 

 parts, but these are too long and intricate to be given 

 in this brief article.
