96 Scientific Intelligence. 



nificance was not fully understood until a visit to the place by 

 Professor G. F. Wright and a party of friends from Cleveland on 

 the 11th of April. The glacial terrace is here thirty-five feet 

 above the flood-plain of the river, and the implement was found 

 by Mr. Mills in undisturbed gravel fifteen feet below the surface. 

 Additional interest pertains to this discovery because of the pre- 

 visions made by Mr. Wright of such discoveries in this valley 

 immediately after his survey of the region in 1881, and reported 

 at considerable length in this Journal, July, 1883, p. 44.

 mammals, well illustrated, and one by A. C. Ranyard, on the 

 great bright streaks which radiate from some of the larger lunar 

 craters, illustrated by an admirable photo-engraved plate from a 

 photograph taken with the great Refractor of the Lick Observa-

Professor Richard Owen. — A letter to the editors from Pro- 

 fessor G. C. Broadhead of Columbia, Missouri, states that Pro- 

 fessor Richard Owen was assistant to Professor Norwood on the
