The question seems to be settled, with considerable certainty, that nothing exists inside of Mercury large enough to be dignified by the name of planet. There may be, and there probably are, for the perturbations of Mercury indicate it, multitudes of small masses circulating around the sun like the planets, being fragments of comets or condensations of primitive matter, whose combined luster is seen in the zodiacal light.
The other results of the work of the Commission, so far as now known, are connected with the structure of the corona, the solar appendage which extends out for millions of miles from the sun's disk. In the photographs of the Egyptian eclipse of last summer these streamers can be traced back of each other where they cross; no better proof of their extreme tenuity could be given.
The duration of an eclipse of the sun depends on three things, the distance of the sun from the earth, the distance of the moon from the earth, and the distance of the station from the equator. All of these were favorable to a long eclipse in the case of the recent one, and the six minutes of totality gave opportunities for deliberate work not often enjoyed.
A BURIED CITY OF THE EXODUS.
The excavations at Tell-el-Maskhutah, of which illustrations are given, have resulted in some of the most interesting and important discoveries that have ever rewarded the labors of archæologists. The idea of founding an English society for the purpose of exploring the buried cities of the Delta originated with Miss A. B. Edwards, the well-known authoress of "One Thousand Miles up the Nile," and was carried into effect mainly by her own efforts and the energy and zeal of Mr. Reginald Stuart Poole, of the British Museum, aided by the substantial support of Sir Erasmus Wilson, without whose munificent donations the work could never have been accomplished. The "Egypt Exploration Fund," thus founded and maintained, was fortunate in securing the co-operation of M. Naville, the distinguished Swiss Egyptologist, who set out for Egypt in January of this year with the object of conducting the explorations contemplated by the society. After a consultation with M. Maspero, the Director of Archæology in Egypt, who has throughout acted a friendly part toward the society's enterprise, M. Naville decided to begin his campaign by attacking the mounds at Tell-el-Maskhutah, on the Freshwater Canal, a few miles from Ismailia. The mounds of earth here were known to cover some ancient city, for some sphinxes and statues had already been found; but what city it could be, archæologists were at a loss to determine; though some, with Professor Lepsius at their head, believed it to be none other than the Rameses or "Raamses," which the Children of Israel built for Pharaoh, and whence they started on their final Exodus. Any identification, however, of the sites of the Biblical cities in Egypt was so far merely speculative. Practically nothing definite was known as to the geography of the Israelite sojourn, except that the Land of Goshen was undoubtedly in the eastern part of the Delta, and that Zoan was Tanis, whose immense mounds are to form the next subject of the society's operations. The route of the Exodus was as uncertain as everything else connected with Israel's sojourn in Egypt. What sea they crossed, and where, and by what direction they journeyed to it, remained vexed questions, although Dr. Brugsch had set up a plausible theory, in which the "Serbonian Bog" played an important part.
