What would any engineer, or simple worker in metal, wood, or stone, think of an alleged _standard_ measure or cubit which varied so enormously from its own alleged length? But, surely, such facts and such results require no serious comment. In this, his latest communication on the Pyramids, Professor Smyth also offered some new calculations regarding the measurements of the interior of the broken stone coffin standing in the King's Chamber. Formerly (1864), he elected the cubic capacity of this sarcophagus to be 70,900 "pyramidal" cubic inches; latterly he has elected it to be 71,250 cubic inches. According, however, to his own calculations, he found, practically, that it measured neither of these two numbers; but instead of them 71,317 pyramidal inches (_see_ vol. iii. p. 154). The capacity of the interior of this coffin does not hence correspond at all to the supposititious standard of 71,250 pyramidal cubic inches; but in order to make it appear to do so he has now struck a "mean" between the measurement of the interior of the vessel and some of the measurements of its exterior, in a way that was not easily comprehensible in his demonstration. But what other hollow vessel in the world, and with unequal walls too (_see_ p. 233), had the capacity of its interior ever before attempted to be altered and rectified by any measurements of the size of its exterior? What, for example, would be thought of the very strange proposition of ascertaining and determining the capacity of the interior of a pint, a gallon, a bushel, or any other such standard measure by measuring, not the capacity of the interior of the vessel, but by taking some kind of mean between that interior capacity and the size or sizes of the exterior of the vessel? According to Messrs. Taylor and Smyth, this standard measure--along with other supposed perfect metrological standards--in the Great Pyramid is "of an origin higher than human," or "divinely inspired;" and yet it has proved so incapable of being readily measured, and hence used as a standard, that hitherto it has been found impossible to make the _actual_ capacity of this coffer to correspond to its standard theoretical or supposititious capacity; whilst even its standard theoretical capacity has been declared different by different observers, and even at different times by the same observer, as shown previously at p. 231.
