F. +THE ERECHTHEUM: RECENT INVESTIGATIONS.+--During the past two years, extensive repairs and partial restorations of the Erechtheum at Athens, undertaken by the Greek Archæological Society, have afforded opportunities for a new and thoroughgoing study of the existing portions of the building and of the surrounding ruins. In these investigations a prominent part has been borne by Mr. Gorham P. Stevens, representing the Archæological Institute of America, to whom must be credited, among other things, the demonstration of the existence, in the east wall of the original structure, of two windows previously unknown. Other peculiarities of design and construction were also discovered, which add greatly to the interest of the building. These investigations are reported in the _American Journal of Archæology_, Second Series; _Journal of the Archæological Institute of America_, Vol. X., No. 1, _et seq._ The illustrations, Figures 35 and 36, are, by Mr. Stevens’ courtesy, based upon, though not reproductions of, his original drawings.
