tion and the Evolution of Carbon Dioxid.' 

 In this part he summarizes previous contribu- 

 tions to the subject and describes improved 

 apparatus for respiration experiments, and an 

 accurate method of titration, on which the 

 somewhat surprising results to be set forth 

 in the second instalment are based. — Professor 

 Charles S. Sargent enumerates the species of 

 ' The Genus Gratwgus in Newcastle County, 

 Delaware,' including notes on the old species, 

 and the description of eight new species and 

 two new varieties. — Mr. William H. Long, 

 Jr., monographs ' The Eavenelias of the 

 United States and Mexico.' From the genus 

 Bavenelia, the species B. Holwayi, having 

 seeidia without pseudoperidium, is separated 

 to constitute the genus Neoravenelia, and the 

 six species having the inner teleutospores two- 

 celled are segregated as a new genus, Pleo- 

 ravenelia. Three new species of Bavenelia 

 and two of Pleoravenelia are described. Diag- 

 nostic structures of the various species are 

 shown on the two double plates. — Frederick H. 

 Billings has found chalazogamy in the pecan, 

 whose close alliance with the walnut, in which 

 this mode of tube entry was first described, 

 makes the discovery seem quite natural. Mr. 

 W. C. Coker contributes various brief notes; 

 one on leaf variation in Liriodendron; an- 

 other on the occurrence of two egg cells in the 

 archegonium of Mnium, from each of which a 

 ventral canal cell is cut off; another on the 

 nucleus of the spore cavity in prothallia of 

 Marsilia. This nucleus enlarges greatly as 

 development of the prothallium proceeds, pro- 

 trudes two or more arms and filaments toward 

 the prothallium, and later fragments amitoti- 

 cally. — Mr. Westgate reviews Gerhart's book 

 on dune work in Germany, and Mr. Howe the 

 volume of Boppe and Joylet on the forests of 

 France. — There are nine pages of notes on 

 current literature and three pages of news 

 items. 



The Popular Science Monthly for March 

 contains some ' Hitherto Unpublished Letters 

 of Charles Darwin,' an account of ' The 

 Vienna Academy of Science,' by Edward F. 

 Williams, and the eighth paper by Frederick 

 A. Woods on ' Mental and Moral Heredity in 

 Royalty,' which considers the evidence from 



Lehr's Genealogy. Edwin G. Dexter considers 

 ' High-Grade Men : In College and Out,' pre- 

 senting some evidence to show that men who 

 stand high in college retain their position in 

 after life. Eaphael G. Zon discusses ' The 

 Source of Nitrogen in Forest Soil ' and R. H. 

 Thurston ' Education for Professions,' sum- 

 ming up that prerequisites for success are per- 

 fect training of body, brain and soul. John 

 Quincy Adajns considers ' Science versus Art- 

 Appreciation,' but we believe he errs in 

 stating that science has not only driven art 

 into the background, but has misrepresented 

 its character. The concluding article is by S. 

 W. Williston, on ' The Fossil Man of Lansing, 

 Kansas,' giving a good description of the con- 

 ditions under which the remains were found 

 and a careful consideration of the possible age 

 of the specimen. ' The Progress of Science ' 

 contains critical articles on the Smithsonian 

 Institution and Carnegie Institution. 



The Plant World for February contains the 

 third instalment of ' Extracts from the Note- 

 Book of a Naturalist on the Island of Guam,' 

 by W. E. Safford, ' Notes on the Flora of Cen- 

 tral' Chile,' by George T. Hastings, ' Condi- 

 tions of Plant Growth on the Isle of Pines,' 

 by W. W. Eowlee and other shorter articles. 



The Museums Journal of Great Britain for 

 February has ' A Design for the Tops of Table 

 Cases,' by A. Jukes-Brown, and a considera- 

 tion of ' The Use of Museums in Teaching,' 

 by W. E. Hoyle, with special reference to the 

 Manchester Museum. Among the notes is one 

 entitled 'A Statesman's View of Museums,' 

 showing the high value set on them by Mr. 

 James Bryce, and the announcement of the 

 completion of a large additional building for 

 the Kew Herbarium.
