On the History of the Arch. By Dr Traill. 



Dr Traill stated, as the result of a careful examination of the 

 passages in ancient authors, supposed to prove the early use of 

 arches by the Greeks, that we must abandon all hope of solving 

 this disputed point, by a reference to those authors ; and he in- 

 stanced the danger of inferences from such uncertain data, by com- 

 paring the description of the Treasury of Minyas, given by Pausa- 

 nias, with the still remaining kindred edifice, the Treasury of the 

 Atridse at Mycena;. He also noticed the loose sense in which the 

 ancient Greeks employed the terras 5»A«?, -^ctUt,. 'a-^/*?.
