It was clearly unknown to Rondelet, and but for thework of Lebrun already quoted, we might never have been led to the investigation of author himself, as we believe, did not entertain any notion of it. In the Corinthian arcade with pedestal we have Whole area, 32xl6*5- - - - - - =52800 12xI2x-7854 Area of semi-arch,Below it, 19x 12 Entablature, 16-5 x 5-09Leaves for supporting parts 56-05= 228-00Total area of voids, therefore, = 284 -05 243-95= 84-10 159-85 Thus, again, the law seems to be borne out, and to prove that the assumptions we havebeen making are not those of empiricism. 2632.

We are not of the opinion of Sir William Chambers in respect of the arcadeswhich ^ignola has given ; that author liad not, we think, critically examined their comjio-sition, and we confess we do not tliink his own examples are improvements on those of tliemaster in question; but we are willing to admit that in the examples of arcades withpedestals, they would have been much improved by assigning a greater height generallyto the plinths of the pedestals, which are, doubtless, much too low, and might be wellaugmented by adding to them a portion of the dies of the pedestals. 2634. Great as is our admiration of Palladio, we do not think it necessary to say morerelative to his arcades, than that he has given only designs of arches with pedestals, andthat their height is from one and two thirds to two and a half of their width. His piersare
