SCIENTIFIC JOURNALS AND ARTICLES. 

 The November-December number of The 

 Journal of Geology, which is the final one of 

 Vol. XII., contains as the leading article Pro- 

 fessor Wm. M. Davis's address before the De- 

 partment of Earth Sciences in the World's 

 Congress of Science and Arts at St. Louis on 

 ' The Relations of the Earth Sciences in View 

 of their Progress in the Nineteenth Century.' 

 Dr. S. W. Williston contributes a ' Notice of 

 Some New Reptiles from the Upper Trias of 

 Wyoming ' which were secured by the Uni- 

 versity of Chicago paleontological expedition 

 of last summer. Pour new genera and spe- 

 cies are described. Messrs. S. R. Capps and 

 E. D. K. Leffingwell describe the ' Pleistocene 

 Geology of the Sawatch Range, near Lead- 

 ville, Colo.' Professor Rollin D. Salisbury 

 describes ' Three New Physiographic Terms ' 

 which are topographic unconformity, topo- 

 graphic adjustment and superimposed youth. 

 0. W. Wilcox has an article ' On Certain 

 Aspects of the Loess of Southwestern Iowa ' 

 and Miss I. H. Ogilvie describes ' The Effect 

 of Superglacial Debris on the Advance and 

 Retreat of some Canadian Glaciers.' The 

 conclusion is ' that the debris covering, and 

 that alone, is responsible for the advance, 

 and indeed for the continued existence, of 

 the glaciers of the eastern Rockies.' 



The American Geologist for January con- 

 tains a ' Biographical Notice of William 

 Henry Pettee ' with plate by Professor Israel 

 C. Russell. Mr. George F. Becker's address 

 before the Geophysical Section at the Inter- 

 national Congress of Arts and Science at St. 

 Louis on the ' Present Problems of Geo- 

 physics ' is published. Professor J. F. White- 

 aves contributes an article entitled ' Notes on 

 the Apical End of the Siphuncle in some 

 Canadian Endoceratidae, with Description of 

 Two Supposed new Species of Nanno,' which 

 is illustrated by two plates. ' The Progress 

 of Vertebrate Paleontology at the American 

 Museum of Natural History, New York,' is 

 reported by Mr. O. P. Hay. ' The Compara- 

 tive Accuracy of the Methods for Determin- 

 ing the Percentages of the Several Com- 

 ponents of an Igneous Rock ' is discussed by 

 Mr. Ira A. Williams. Mr. W. C. Morgan con- 



siders ' The Origin of Bitumen,' and from the 

 discovery of a fossil egg partly filled with 

 asphalt concludes that ' natural conditions are 

 thus demonstrated to be sufficient to trans- 

 form animal matter into bitumen during long 

 periods of time without the aid of heat.' 

 There are also given abstracts of papers pre- 

 sented at the Philadelphia meeting of the 

 Geological Society of America by Professors 

 Cumings, Tarr and Willis and Mr. Fuller.
