cc Architrave upon them, without Danger of breaking, and being" but iix Foot high, there could not possibly be a convenient Head-" height remaining for a Passage underneath; especially, consider-« ing" fully the Greatness of the Whole Work.

" The Stones of the greater Hexagon , are seven Foot and an“ half in Breadth, three Foot nine Inches in Thickness, and twenty£t Foot in Height; each Stone having one Tenon in the middle.

" The Stones of the Hexagon within, are two Foot fix Inchestc broad, one Foot and an half thick, and eight Foot high; in Form" pyramidal, like those of the inner Circle.

" The Architrave lying round about upon the upright Stones" of the outward Circle, being mortaised into them, and jointed" in the middle of each of the perpendicular Stones, is three Foot" and an half broad, and two Foot and an half high.

" The Architrave which lyeth on the Top of the great Stones of" the Hexagon , and mortaised also into them, is sixteen Foot long," three Foot nine Inches broad, and three Foot four Inches high." This Architrave continuing only from Stone to Stone, left be-“ r twixt every two and two a void Space, free to the Air, uncovered.“ For if they had been continued throughout the whole Hexagon ," then necessarily there must have been two Tenons upon each of" the said Stones, as those of the outward Circle had; but.being“ disposed as aforesaid, that one which was in the middle, and yet“ remains apparent, was sufficient for the thing intended.

Thus Mr. Jones concludes his Description of our Antiquity jwherein it’s not unworthy our Notice, that whatever in the wholeWork might seem doubtful, he hath endeavoured, by firm and so-lid Reasons, to make the fame manifest and evident,

Unto this Account given by Mr. J ones r this Doctor adds: " Af-" ter this Survey, and some other Designs that he (meaning Mr.“ Jones) fancied correspondent thereunto, he obligeth his Readers" with the whole Work in Prospective, as it now lies in its Ruins.

Alas, good Man! we find him too weak already to judge of Mr.Jones his Designs, and weaker shall, ere long; for we are now ar-rived at the Use that he makes of both Descriptions.

“ Reflecting, faith he, upon these two Descriptions, and com-'“ paring them together with due Care, you’ll find them at open" Variance, and differing in so many, and so considerable Particur" lars, that ’twill be a hard Task for you to keep them from mm" tually discrediting each other.

I have always observed in reading, that ingenious and trulylearned Men have usually extenuated and sweetned the Failuresand Mistakes of others, rather than multiplied and encreased them.But seeing the Authors traduced are past answering for themselves,bein°- dead, long since in their Graves, and possibly e’re this timeconsumed to Assies, I shall attempt (since that he tells you st i s suchan hard Task) to reconcile them; and, though to Matters of thisnature I pretend not much, doubt not to make it out,. that therewill be found no such open Variance between them, no such Dif-ference in so many and so considerable Particulars, and no such disficult Work to keep them from mutually discrediting each other,as this Doctor would enforce you to. believe.
