FiiRSTEMANN.] CENTRAL AMERICAN TONALAMATL 538 



days from each other, in tlie third the same with reference to the 

 week days, and in the fourth the entire resuUino: period: 



In addition, tliere is the somewhat difi'erently arran^jred passage, 

 pages 32a to 39a, where 16X13=208 days are given, which point to 

 10X-08=8X2G0. I have ah-eady discussed three of these six pas- 

 sages in my Erhiiiterungen, pages 26 to 27. 



I am ghid to be able to add to this table two pai-allel cases from 

 Codex Troano-Cortesianns : 



Codex Cortesianiis, page 10a 4 104 5X104=2X260 

 Troano codex, pages 31c to 30c 19 39 20X 39=3X260 



The reason for these multiple tonalamatls is obvious: 2G0 is not 

 divisible without remainder by 39, 78, 91, 104, and 117, as it is by the 

 numbers mentioned above, 20, 52, and 65. 



In addition to the main object of this article, I desire to point out 

 for the first time that the two highest intellectual productions of the 

 Western Hemisphere, so far as we now know, the Dresden and the 

 Madrid manuscripts, with all their points of ditference, show very 

 surpi^ising similarities, which prove them to be much niore nearly 

 related than has been hitherto su])p()sed. It is uimecessary to discuss 

 here the tonalamati in Codex Cortesianus, pages 31 to 39, where it is 

 completely written out with all the 200 days.
