of the year (a week) determined to be seven days, for it was 

 in common use long before tlie birth of Moses ? Wliy was the 

 seventh day originally set apart as the Sabbath ? Why have 

 we the day divided into two parts of 12 hours each, and why 

 do multiples of 12 so commonly appear in weights and 

 measures, especially in astronomical divisions ? 



In many combinations conducted with the hoj)e of throwing 

 light on such matters, I failed to get any remarkable indica- 

 tions, with three important exceptions. These three exceptions 

 possess so many remarkable proportions and numbers relating 

 to existing sub-divisions of weights, measures, and values, and 

 especially with the proportions and dimensions of the G-reat 

 Pyramid, that I have been induced to risk the appellation of 

 "pyramid mystic," and to lay the remarkable results before 

 the members of this Society. 



The models which appear before you have each some 

 particular claim to notice, and whether any of them may offer 

 sufficiently remarkable characteristics or not as bearing upon 

 the Grreat Pyramid, they are all well worthy of close attention as 

 offering a natural solution to the genesis of particular numbers 

 as used in sub-divisions or measures of time, space, weight, or 

 value. 



Pyramid of Odb Numbees, Having 7 as a Base. 



As shown in diagram, the most remarkable characteristic is 

 the fact that the cube root of its basal layer, 49 or 7^, enters 

 into and agrees with all the imjiortant dimensions of the 

 G-reat Pyramid, including length of complete circuit ; length 

 of side ; height ; length of Egytian cubit ; Enghsh inch ; and 

 through the latter it harmonises in the most obvious and 

 simple multiples with these dimensions and the days in the 

 year, days in the lunar month. Other natural proportions of 

 the three angled sides of jjyramid connote the months in 

 the quarter and year ; while its aggregate number of cubes, 

 84 or 7 times 12, suggest the alliance of 7 and 12 in 

 measurement of time.

Demonstration indicating that the G-reat Pyramid dimen- 

 sions were probably determined by the radix of sacred num- 

 ber (7), which in itself has probably been selected because 

 the cube root of its squai'e contains nearly the exact figures 

 representing the known days in the year : —
