interesting, however, to note that the present issue includes 

 upwards of a hundred pages more than the first edition of 1908 ; 

 this shows the care and thoroughness with which the author has 

 brought the subject up to date. 



13. Guida al Corso cli Miner alo g ia : Mineralogia Generate, 

 Second edition; by Giovanni d'Achiaedi. Pp. 543; 576 text- 

 figures. Pisa, 1915 (Enrico Spoerri). — The first edition of this 

 valuable work, by the distinguished mineralogist of Pisa, Pro- 

 fessor Antonio d'Archiardi, appeared in 1899 (see vol. ix, p. 160). 

 It is pleasant to note that this second edition is by the son of the 

 original author and his successor at the University of Pisa. The 

 work has been rearranged and much enlarged, and will doubtless 

 have a still wider circle of usefulness than its predecessor.

 Bidletin, vol. VIII, No. 1, January, 1916. List of Meferetices on 

 concentrating ores by flotation / compiled by Jesse Cunningham, 

 Librarian. Pp. 106; 2 pis. Rolla, Mo., 1916. — This bibliography 

 is based upon the library of the School of Mines and has been 

 prepared primarily for the use of its students engaged in experi- 

 ments in the flotation laboratory. It is expected, however, that 

 it will serve as a guide to the general study of the subject. Some 

 900 titles are included, and a special section (pp. 44-51) is devoted 

 to the subject of colloids and surface tension as related to the 

 important theory of oil flotation processes. The publications of 

 the Institution since its beginning in 1902 make an impressive 

 total of 299 volumes with 79,500 pages. 



III. Miscellaneous Scientific Intelligence. 



1. Carnegie Institution of Washington; Robert S. Woodward, 

 President. Tear Book No. U, 1915. Pp. 429; 3 pis., 4 figs. Wash- 

 ington, 1916. — The decade which has passed since Dr. Woodward 

 became president of the Carnegie Institution has been an important 

 period in the development of its policy and in the experience 

 which has been gained in regard to the most effective methods of 

 promoting scientific research. This subject is taken up in detail, 

 and the presentation is not only of great interest to the general 

 public, but of especial value to other institutions having more or 

 less similar ends. The aggregate amount allotted for the work 

 of the Institution during the past year was upwards of $1,250,000, 

 but even w T ith this large income it is still subjected to very defi- 

 nite limitations and any considerable increase in its scope is not 

 to be looked for. On the contrary, the considerable diminution 

 in the purchasing power of money during the past twenty years 

 has made it essential to curtail research in order to live within 

 income ; it is, hence, much to be desired that the endowment 

 fund may be increased. 



Of the total amount allotted for the year as already stated, a 

 sum of upwards of 8700,000 was devoted to the larger depart-
