MEMORIAL OF G. F. WRIGHT 19 



after revision and enlargement for publication in 1889, formed a book 

 of 622 pages, entitled "The Ice Age in Xorth America and its Bearings 

 upon the Antiquity of Man." The fifth edition, enlarged to 763 pages, 

 was issued in 1911, and the sixth edition in 1920, with an added preface 

 of 26 pages. 



During the summer and early autumn of 1892 Professor Wright, 

 again accompanied by Prentiss Baldwin, visited the glaciers of the Alps 

 and examined many localities of archaeological interest in France, Bel- 

 gium, and southern England. Late in that year he published "Man 

 and the Glacial Period," 385 pages, as volume 69 in the International 

 Scientific Series of D. Appleton and Company. The part treating of 

 the ancient glaciers of Great Britain was contributed by Prof. Percy F. 

 Kendall, of England, and an appendix on "Tertiary Man/' by Prof. 

 Henry W. Haynes. 



In 1894, with an excursion party in the steamship Miranda, Wright 

 visited southern Greenland and expected to reach Disco Bay and Jacobs- 

 havn, but an irreparable damage to the Miranda, by running upon a 

 reef near Sukkertoppen, caused the expedition to be abandoned, with 

 rescue and return in a small fishing schooner. Two years later he pub- 

 lished "Greenland Icefields and Life in the Xorth Atlantic," 407 pages, 

 including collaboration by the writer of this memorial, who supplied 

 chapters on the flora and fauna of Greenland, its inland ice-sheet, and 

 the causes of the Ice Age. 



His second course of Lowell Institute lectures, in March. 1892, was 

 on the "Origin and Antiquity of Man," which was chosen as the title 

 of his latest book devoted to these subjects, published in 1912 by the 

 Bibliotheca Sacra Company. 



In addition to the extensive journeys in the United States, Canada, 

 Alaska, and Greenland, Professor Wright also made four visits to Europe, 

 for increase of his knowledge in glacial geology and archaeology. The 

 first was in 1892, as before noted; the second, on a tour through Asia 

 and westward around the world, in 1900 and 1901; the third in 1905. 

 and the fourth in the autumn and winter of 1907 and 1908. His ob- 

 servations and researches during these travels are in part narrated, with 

 a very interesting review and reminiscences from childhood to the age 

 of nearly eighty years, in the "Story of My Life and Work," 459 pages. 

 published in 1916. 



From the circuit of the world, accompanied by his son and aided by 

 him in the authorship, came two volumes in 1902, entitled "Asiatic Eus- 

 sia," in 637 pages, with numerous maps and other illustrations. The 

 autobiographic "Story" gives its longest chapter, of 149 pages, to an
