A Treatise on the Chronology of Siriadic Monuments. By Hekekyan

Bey, C.E. (For private circulation.)—This gentleman, who was formerly in the Egyptian service, has convinced himself by researches "into the physical constitution of the Nile volley," and "the gnomic properties of the existing monuments of Phaaronie dates," that the science of the priests of Egypt concerned the application of geology and astronomy to agriculture. This r scienee of Khemy" still flourishes. Egypt, it seems, is gradually'fanking, and the priests by means of it direct the embankment of the river and the raising of the soil of the country by the deposit which the river brings down. `" The astrogeological system" gave birth to the monuments of Egypt, which have "the essential property of being antochronous landmarks of a geochronolo- gical nature," and "many of them record hydromathematioally the knowledge in astronomy, in geography, and in the dimensions and figure of the earth obtained in their respective epochs." So the Manothonian lists of dynasties are "a copy of a connected series of Nile observations in the great Memphis Niloscope," and the object of the author is "to restore them to their original state." We cannot pretend to have been able to understand the writer's theories, andmust, therefore, refer our readers to the book itself, though, as it has no publisher, we do not know exactly how they are to get it.
