of Anticosti, and detailed Dr. Joseph Schmitt as resident phy- 

 sician and naturalist. The work cited describes the local geog- 

 raphy, history, meteorology, geology, paleontology, botany, 

 zoology, anthropology, maladies of man and animals, agriculture, 

 and resources. There is also a bibliography of the island, 19 

 pages in length. 



The Ordovician and Silurian stratigraphy is described in con- 

 siderable detail on pp. 65-99. The divisions as established by 

 Richardson and Billings are here accepted. Many of the more 

 important geological localities are shown in full-page half-tones, 

 the best we have seen of that island. The list of fossils on pp. 

 100-128 gives the horizons and localities for each species, with 

 occasional remarks on certain forms. The book does credit to 

 the present owner of the island, and especially to its author, Dr. 

 Schmitt. c. s. 



5. Handbuch der Mineralogie ; von Dr. Carl Hlntze. Erster 

 Band, achte Lieferung. Pp. 1121-1280.— The eighth part of the 

 first volume of Hintze's great work has recently appeared. It 

 contains the closing portion of the sulphur compounds, ortho- and 

 basic sulpho-salts, sulpharseniates, oxysulphides, etc , and the 

 beginning of the oxides. The closing pages are devoted to the 

 species quartz. The part now issued is the twentieth of the 

 entire series, which was begun in 1889. 



6. Volcanic Pipes of Sutherland. — In the annual report of 

 the Geological Commission of the Cape of Good Hope for 1903, 

 Mr. A. W. Rogers and A. L. duToit give an account of some 

 circular patches and dike-like outcrops of igneous rocks near the 

 village of Sutherland. These "pipes" resemble closely the 

 Kimberly pipes in form and relation to the surrounding rock, and 

 some of them contain breccia similar in character to the diamond- 

 bearing blue-ground of Kimberly. Melilite-basalt occurs in close 

 connection with them, filling some pipes and forming dike-like 

 masses around them. A complete petrographic description is 

 given of these rocks, and the following analysis of melilite-basalt, 

 from the Spiegel River, was made by J. Lewis. 



Analysis of melilite-basalt : Si0 2 36*15, Ti0 2 2-30, Al a O, 15-18, 

 Fe, 2 3 4-87, Cr 2 O 3 -10, Fe0 9'll,*MnO -33, CaO 11-40, MgO 13-63, 

 BaO -06, Na 2 2-42, K 2 1-81, P 2 5 '26, S0 3 -49, H 2 on igni- 

 tion 1-95, H 2 G driven off below 110° C. '37 = 100*43. 



It will be remembered that Professor Carvill Lewis felt very 

 confident that melilite rock was closely connected with the origi- 

 nal form of the Kimberly blue-ground, and it seems probable that 

 the Sutherland area presents some of the same geological charac- 

 teristics as the Kimberly district. 



7. A Treatise on the British Freshwater Algw ; by G. S. 

 West; pp. xv + 372, with 166 text-figures. Cambridge, 1904 

 (The University Press). — The need of a modern account of the 

 freshwater algae has long been felt by English-speaking botanists,

 iron is included. The sulphur present as sulphide is included in the SO s .
