bioeraphy will be a valuable contribution to the history of the last 

 half-century of our national life. The second volume of " Hermetic 

 Philosophy," by Styx of the " H. B. of L." will soon be issued by 

 the same publishers. As in the first volume, it includes lessons, 

 general discourses, and explanations of "Fragments" from the 

 schools of E?ypt, Chaldea, Greece, Italy, etc., and is a continua- 

 tion of the line of thought treated in that work. One of the ac- 

 quisitions to medical literature of the year will be the new edition 

 of Professor Roberts Bartholow's " Hypodermatic Medication," 

 about to be issued from the press of the same company. 



— The J. B. Lippincott Company of Philadelphia have published 

 an octavo volume entitled " Harmony of Ancient History," by 

 Malcomb Macdonald. It is an attempt to determine the dates of 

 the best known events in Oriental History and to harmonize the 

 chronology of the Egyptians with that of the Jews. Our knowl- 

 edge of Egyptian chi-onology was formerly confined to the state- 

 ments of the Greek historian Manetho, but we now have the 

 testimony of the Egyptian monuments to aid us; yet the best 

 modern authorities differ by many centuries as to the dates of 

 Egyptian kings. On the other hand, the Bible chronology, besides 

 being sometimes inconsistent with itself, is not in accord with 

 that of Egypt and other nations, and the result is a mass of doubt 

 and confusion. Mr. Macdonald has here endeavored to fix tlie 

 dates of some Egyptian kings by means of astronomical phenomena 

 recorded on the monuments whose occurrence our modern astron- 



omy enables us to verify. He then proceeds to the Jewish chro- 

 nology with the avowed purpose of showing that it harmonizes 

 with that of Egypt and Assyria; and he claims for his scheme that 

 " there is not one single chronological statement in the Bible from 

 which it does not remove all improbability." To attain this end, 

 however, he is obliged to resort to some devices and interpreta- 

 tions that seem forced and arbitrary, and he admits that "the 

 whole scheme rests largely on circumstantial evidence." For our 

 part we doubt if any reconciliation of the ancient chronologies is 

 possible, the gaps in the monumental records being so great and 

 other ancient histories so largely mythical as to preclude a satis- 

 factory solution of the problem; but Mr. Macdonald has made 

 an elaborate attempt at such reconciliation, and we leave the 

 criticism of his work to those who have made a special study of 

 the subject. 



— The newest of important educational movements, "Univer- 

 sity Extension," will have first place in the Popular Science 

 Monthly for November. The article is by Professor C. Hanford 

 Henderson, and, after sketching what has been done in England, 

 it describes the beginning that has been made in this country, and 

 tells the plans of the extension organizers for the future. In the 

 same number Mr. W. F. Durfee will conclude his contributions to 

 the series of illustrated articles on the development of American 

 industries with a paper on "The Manufacture of Steel." This 

 paper completes the account of the Bessemer process, and proves
