the work. A goodly treatise on each drug is 

 found, embracing references to its origin; 

 discussions of its gross structure, microscopic 

 structure and features recognizable in its 

 powder; and mention of constituent substances 

 present. 



Although no attempt is made to include all 

 the drugs, yet few important ones will be 

 missed by the student looking for informa- 

 tion. 



Excellent original illustrations accompany 

 a large number of the descriptions. It is 

 to be regretted that these are in some cases 

 replaced by inferior mechanical reproductions 

 of plates in larger works. 



The discussions are in the main botanically 

 correct and the style is fairly clear. The 

 treatment of Polygala senega leaves something 

 to be desired from the standpoint of anatomical 

 accuracy. One wonders a little, too, at such 

 expressions as ' Therefore the cork cambium 

 of the wood bark produces an apparently abun- 

 dant periderm,' and ' the nucleus of the young 

 plant,' in speaking of the structure of seeds. 



Imperfections aside, however, it is well 

 within the truth to say that this volume is 

 the nearest approach which has yet appeared 

 towards filling the need of the day in this 

 country.

8CIENTIHC JOURNALS AND ARTICLES. 

 The January— February number of The 

 Journal of Geology, which is the first one of 

 Vol. XIII., contains a paper by Professor 

 Albrecht Penck, of the University of Vienna, 

 on ' Glacial Features in the Surface of the 

 Alps.' He concludes that " The actual sur- 

 face features of the Alps do not at all cor- 

 respond to those of a water-worn mountain 

 range. Their conformation is mostly due to 

 ice-action." Mr. E. B. Branson contributes a 

 systematic paper on fish teeth, entitled * Notes 

 on Some Carboniferous Cochliodonts, with 

 Descriptions of Seven New Species,' which is 

 illustrated by two plates. Dr. Charles P. 

 Berkey describes the ' Laminated Clays of 

 Grantsburg, Wis. (with Chronological Deduc- 



tions),' which is illustrated by a map showing 

 the glacial deposits of that region. Mr. Ed- 

 ward M. Shepard gives an interesting account 

 of ' The New Madrid Earthquake,' accom- 

 panied by five figures, and states that ' the ele- 

 vation and depression of the land in the New 

 Madrid region * * * were due to the great 

 artesian pressure from below.' Dr. Charles R. 

 Keyes contributes a paper, with five figures, 

 on the ' Structure of Basin Ranges ' as found 

 in New Mexico. Professor Stuart WeUer 

 contributes a valuable article on ' The Classi- 

 fication of the Upper Cretaceous Formations 

 and Faunas of New Jersey.' It contains a 

 valuable chart showing the equivalence of the 

 classifications of Cook, 1868; Clark, 1892- 

 1904; Knapp-Kiimmel, 1898-1904; and Weller, 

 1905. 



The American Geologist for February con- 

 tains, as the leading article, a paper by Dr. 

 Alfred C. Lane on ' The Coarseness of Igneous 

 Rocks and its Meaning,' illustrated by a plate 

 showing the ' Luster-mottling in Drill-cores 

 of Ophites.' Professor L. C. Glenn contrib- 

 utes a biographical sketch, with portrait, of 

 ' Gerard Troost,' the first state geologist of 

 Tennessee. ' Notes on Some Rocks and Min- 

 erals from North Greenland and Frobisher 

 Bay,' illustrated by a plate showing the banded 

 limestone of Frobisher Bay, is published by 

 Professor B. K. Emerson. The ' Montana 

 Gypsum Deposits ' are described by Professor 

 Jesse P. Rowe. The deposits are divided into 

 the North Field, concerning which little is 

 known; the Middle Field, given as of Carbon- 

 iferous age; and the South Field, which is 

 regarded as in the same formation as the 

 gypsum beds of Wyoming and as of Permian 

 or Triassic age. The paper is illustrated by 

 three plates giving six views of the gypsum 

 deposits and a map showing their distribution. 



The Museum News for April, published in 

 the interest of the museums of the Brooklyn 

 Institute is issued in place of the Children's 

 Museum News and will deal with matters re- 

 lating to both the Central and Childrens' Mu- 

 seums. Its object will be to keep the public 

 advised of changes in and additions to the col- 

 lections, and to note the general work of the
