5. From the meaſures of ancient buildings, now remaining. "Mr. Stuart," as we are told by the editor of the two laſt volumes of the Antiquities of Athens, appears to have taken very great pains to diſcover the true length of the Greek foot, from different meaſures of the temple of Minerva Parthenon; which, from its name Hecatompedon, was ſuppoſed to contain a meaſure of an hundred feet, in ſome conſpicuous part of the building."
The difference of the foot, and the proportion it bears to Engliſh meaſure, taken from various parts of the building, are as follows.
