 V. The Geological Survey of Oklahoma. — At a meeting of 

 the State Geological Commission of Oklahoma, late in December, 

 the resignation of D. W. Ohern as Director of the Oklahoma 

 Geological Survey was accepted. L. C. Snider, the assistant direc- 

 tor, declined to consider the directorship and C. W. Shannon, 

 field geologist, was appointed director. The personnel of the 

 scientific staff of the Survey as now constituted is as follows :

 Geographique. Pp. 501. Paris 1913 (Librairie Polytechnique). 

 — This is the second supplement to the exhaustive work by Pro- 

 fessor Lacroix. It is chiefly given to a geographical index of 

 localities with the species occurring at each. The places are 

 arranged alphabetically under the countries, France, Alsace, Bel- 

 gium, etc.; also Algeria and other French colonies, the most 

 important of which from the mineralogical standpoint is Mada- 

 gascar. The interesting new species from this remarkable island 

 with notes on some other minerals are described briefly in the 

 opening pages.

1. The Semi- Centennial Anniversary of the National Academy 

 of Sciences, 1863-1913. Pp. vii, 108, with illustrations. Washing- 

 ton, 1913. — A memorial volume, giving a history of the first fifty

 p. 185). The semi-centennial anniversary meeting, held in Wash- 

 ington in April, was an occasion of great interest not only to the 

 Academy itself but also as regards American science in general. 

 We have now an account of this April meeting prepared by the 

 Home Secretary, Dr. Arthur L. Day, which gives in detail the
