Mammoth may have been quietly grazing on grass-covered land 

 which had accumulated above a glaciei", when it fell into a hidden 

 crevasse. It was found surrounded partly by ice, partly by 

 frozen earth and gravel ; and, according to the researches of 

 Dr. Tolmatschow, the ice had undoubtedly the character of a glacier 

 formed from snow, not formed directly from a lake or river." 



Dr. Herz is not a geologist, and does not pretend to express an 

 authoritative opinion on the geological aspect of his discoveries. 

 A trained geologist, however, M. Ssewastianow, examined the 

 region of the Beresowka last summer, and we may shortly expect 

 more important observations in his forthcoming Eeport. Meantime, 

 it is clear that the only mammoth-carcase of which we have adequate 

 knowledge represents an animal which fed on grass and met its 

 death as the result of a local accident. It did not depend for 

 sustenance on scrub or forest-growth, as the Mammoth is sometimes 

 assumed to have done. It cannot be regarded as lending any 

 support to the theory of the destruction of these great quadrupeds 

 by a flood or any unusual cataclysm. 



Regarded from the zoological point of view, the new specimen is 

 of supreme importance, and Dr. Salensky is preparing a series of 

 memoirs upon it. The first of these, dealing with the skeleton and 

 teeth, has just appeared, and is illustrated with numerous figures. 

 Our only regret is that his work is not generally accessible on 

 account of it being written solely in the Eussian language.

Eeports on the Scientific Results of the Expedition to the Tropical Pacific, in 

 charge of Alexander Agassiz, by the United States Fish Commission Steamer 

 *' Albatross," from August, 1899, to March, 1900; Commander Jefferson F. 

 Moser, U.S.N. , commanding. IV. The Coral Eeefs of the Tropical Pacific. 

 By Alexander Agassiz. 4to: pp. xxxiii, 410 ; 236 plates. February, 1903. 

 One volume text, three volumes plates. 



IN May, 1899, Alexander Agassiz published in the Bulletin of the 

 Museum of Comparative Zoology, Harvard College, vol. xxxiii, 

 his account of " The Islands and Coral Eeefs of Fiji," with 

 120 plates and 168 pages of text 8vo (see Geol. Mag., pp. 407-421). 



If the earlier work formed a most valuable contribution to the 

 literature of coral reefs, this later and larger memoir is, like the 

 reefs themselves, ' monumental.' 



Professor Agassiz reports that, "While in charge of the Expedition 

 of the United States Fish Commission Steamer ' Albatross ' during 

 the Winter of 1899-1900 we visited the coral reef districts of the 

 Tropical Pacific, with the exception of the Sandwich, the Samoan 

 Islands, and the Galapagos. 



" The Hawaiian Islands I had explored on former occasions, and 

 had also obtained a bird's-eye view of the reefs of Samoa on my way 

 to examine the Great Barrier Eeef of Australia.
