it is admiTably adapted. The subjects covered include the uses 

 of topographic maps in geology, the relation of topography to 

 outcrop, the effect of folds and faults on the outcrops of beds, 

 and the interpretation of geologic maps. The illustrations are 

 specially noteworthy, and are unsurpassed in any work of similar 

 scope. The book should serve as an excellent text in structural 

 geology. A handicap on its wide use outside of Great Britain, 

 however, is that the topographic and geologic maps employed in 

 illustration are exclusively British. Adolph Knopf. 



10. Geological Explorations in Africa. — An important series 

 of investigations of the igneous rocks of South Africa and else- 

 where is being undertaken by a force of American geologists 

 essentially financed by the Shaler fund of Harvard University. 

 Professor R. A. Daly^ the chief mover in the enterprise, has gone 

 on in advance and after a month on Ascension Island will work 

 on St. Helena. Dr. F. E. Wright sailed for England early in 

 November. On December 30 with Professors Charles Palache 

 and Molengraaf of Holland, he will sail for Cape Town where the 

 party will be joined by Dr. Daly. The field-Avork will be chiefly 

 in the Transvaal. 



III. Miscellaneous Scientific Intelligence. 



1. National Academy of Sciences. — The autumn meeting of the 

 National Academy was held in Chicago on Monday and Tuesday, 

 November 14-15, at the University of Chicago. The attendance 

 was large and a notable series of papers were presented. The 

 Academy dinner took place on Tuesday evening. Members of 

 the Academj^ had the opportunity to visit the Yerkes Observa-

2. American Association for the Advancement of Science. — 

 The winter meeting of the American Association, the seventy-

 31. This is the second Toronto meeting, the first having been in 

 1889. Two other meetings in Canada were»those of Montreal in 

 1857 and 1882. All of these meetings have been marked by their 

 international character which has been an important element in 

 their success. It may be added that the membership of the Asso-
