about 40 feet higher, and upon the top of it a vast statue of the 



Sun Within the pyramid of the Moon were vaults luhere 



their kings were buried ; for which reason the road to them is 

 called MicATOLi, that is to say The Way of the Dead. Pre- 

 cisely too after the manner in which the Pyramids of Egypt are 

 surrounded by sepulchres of a more diminutive form, the Mexi- 

 can Pyramids have, as Gmelli tells us, " about them several 

 artificial mounts, supposed to be burying-places of lords," 

 Another instance, and more remarkable for the similitude it 

 bears to the principal pyramid of Egypt, is the great pyramid of 

 Papantla mentioned by Humboldt, in which mortar may le 

 discerned in the interstices between the stones. It is an edifice of 

 very high antiquity, and was always an object of veneration 

 among the Mexicans.

To Mr. Tilloch. 



Sir, — iVlY grateful acknowledgements are due toN. J.Winch, 

 Esq, for his prompt and kind attention in p. 233, to a part erf 

 my Queries in p. 108 of your Magazine. It seems now I think, 

 that the " bivalve shells'"' of Mr. W. are the Myce ovatce of 

 William Martin, and that the " Grindstone sill" of W. Forster 

 (fathom 244 to 247) is a far lower stratum than the Gateshead- 

 ffiU Grindstone sill : but I am still left in ignorance, of the par- 

 ticular strata to which these Myae and Newcastle Grindstone 

 Quarries, are to be respectively referred ? and I presume there- 

 fore to prefer these fiirther requests to Mr. W. or any other kind 

 friend of Geological investigation : reciuesting, in order to avoid 

 mistakes, that they will mention the Name of the stratum and. 

 Fathom on Mr. Forster's attached scale, in each instance. 



In wishing further reference to Mr. Forster's Section to be 

 made, I beg not to be understood by Mr. W. as countenancing 

 plagiarism, or as wishing to keep out of honourable view, the 

 names of those deserving individuals Hutchinson, Johnson, and 

 Miller (Millot must be a misprint) , who are said to have first 

 published the detached details of the Newcastle Coal strata ; but 

 nierely prefer Mr. Forster's work, as being the only collection 

 of these valuable materials, in a portable form : and I shall feel 



T 4 hi-ghly
