ancient altar to Zeus Hypsistos, or Jupiter the Highest, and 

 that the levelled space, with the old supporting wall, is the 

 ancient Pelasgicon. This essay was answered by Professor 

 Ross, formerly of Athens, now of Halle, in a pamphlet, pub- 

 lished in 1853. Welcker replied by another pamphlet in 1854. 

 Professor Felton gave a summary of the arguments on both 

 sides, and stated that the subject had occupied much of his 

 attention while in Athens ; — that he had come to the con- 

 clusion that the received opinion is correct ; — and, in con-

 tion of the authorities, especially Plato, Demosthenes, Plutarch, 

 and Proclus, citing a passage from the last-mentioned author 

 which had never been considered before, and which was pro- 

 nounced to be almost, of itself, conclusive : and quite conclu- 

 sive, as the last term in a cumulative argument, the expres- 

 sions being precisely applicable to the shape of the supposed 

 Pnyx, and to no other place or structure in Athens.
