The coincidence of the hypothesis with the ajiparent law is nuless remarlvahle in this example than it will be found in those that follow ; and, scep-tical as we at first were on tiie appearances which ]H)inted to it, we cannot, after the ex-amination here and hereafter given, do otherwise than express our conviction that, in cai out the principles, no unpleasant combination can W U Vi 13 U 15 IG MoJuUm 2G29. Fig. 904. exhibits the Doric arcade, whose whole area from centre to centre ofcolumns is 374. The area of the void is 189, that of the entablature 62, and of the sup-porting parts 112. The ratio of the entablature to the supports is therefore ^^^=-55, andthat of the supports and weights to the voids 9. The height of the pedestal is almost5 modules and 4 parts, the opening 10 modules, and the width of a pier 4 modules and9 parts. As in the preceding example, wc think it will be useful to detail the process by whichthe general results stated have been arrived at. It is curious and interesting to observetlie similarity between the cases. It is scarcely possible to believe that accident couldhave produced it. INIay not the freemasons of the middle ages have had some laws of thisnature which guided their operations ? B
