photofj-raphefl plates. (See the copy of Plate 50, given in Fig. 3(J2.) 

 Those on a single 23late are as follows: 



( XI, IV, XII, 0, 

 "( XVI, X, X, VIII. 



The here represents a red, diamond shaped symbol. 



If the upper line represents months and the lower line days, these 

 numbers will indicate the intervals between the columns and are 

 properly placed. For example, the XI and XVI signify 11 months 

 and 16 days, the interval between the last column of the preceding 

 plate and the first column of the plate on which they stand; the IV 

 and X, the interval of 4 months and 10 days between the first and 

 second columns; XII and X, the interval of 12 months and 10 days 

 between the second and third columns; and 0, VIII, the interval of 

 8 days between the third and fourth columns. It is apparent from 

 this that the red, diamond shaped symbol represented by over the 

 VIII denotes a cipher or nought, a conclusion reached independently 

 by F('Jrstemann. 



If this supposition as to the arrangement of the series and the signifi- 

 cation of these numbers be correct, it is apparent that the plates are 

 to be taken in the order in which they are- paged, that is, from left 

 to right, as the others si> far noticed, an inference borne out by an- 

 otlier fact now t.. lie iiiciil ioiiwl. 



Immediately below each (if these four column day series are four 

 lines of characters (hieroglyphics), and immediately under the latter 

 three horizontal lines of black numerals, with here and there a red, 

 diamond shaped symbol inserted. As these numerals stand directly 

 in the vertical lines of the day columns, it is possible the two have 

 some connection with each other, a supi^osition somewhat strength- 

 ened by what has been observed in regard to the red numerals at the 

 bottom of the plates. To test this and also for the reason that we 

 l^ropose to discuss their relations and their use, we give here the bot- 

 tom line of days of each of the five series (or plates), together with 

 their week numbers attached ; also, the numbers of the three lines of 

 black numerals mentioned, taking them in the order of the imaging as 

 here shown:
