acid that I am satisfied that my information is from really reliable 

 sources." 



The New Plu/tolor/ist (Aug. 10) contains a continuation of 

 Mr. Walter Stiles's essay on "Permeability"; Mr. W. 11. Black- 

 mail writes on " Osmotic Pressure, Root Pressure, and Exudation " ; 

 Mr. J. Lynn on "The Reversal of Geotropie Response in the Stem" 

 (with plate). The number issued on Aug. 19 contains a continuation 

 of Mr. Stiles's paper, with papers on "Osmotic Pressure, Root 

 Pressure, and Exudation," by V. H. Blackmail, and on " The 

 Reversal of Geotropic Response in the Stem," by M. J. Lynn, 

 D.Sc. 



The Journal of the Linnean Society (Botany, vol. xlv. no. 303 ; 

 Sept. 6) is chiefly occupied by the first part (Angiosperms) of "A Sys- 

 tematic Account of the Plants collected in New Caledonia and the 

 Isle of Pines by Prof. R. H. Compton in 1914." The plants are in 

 the National Herbarium, and have been worked out by its officers — 

 the Monocotyledons by Dr. Rendle, the Polypetahe by Mr. Baker, the 

 Monopetahe and Apetalaj by Mr. Spencer Moore. Eight hundred 

 and thirty species are enumerated, two hundred and thirty of which 

 are new. Among them are ten new genera — these are Compto- 

 nella (Rutacere), Salaciopsis (Celastrinese), Montacjueia (Anacar- 

 diacese), JParacrypMa (Eucryphiaceae), Enochoria (Araliaceae), 

 Men's mostly ma (Rubiacese), Tropalanthe (Sapotaceaa), Depanthus 

 (Gesneraeeae), Adenodaphne (Lauraoeae), and DendropJiyllanthm 

 (Euphorbiaceae). The paper is illustrated hy twelve plates, in which 

 the more interesting plants are figured. The number also contains a 

 revision of Baphia, by Mr. Lester-Garland, enumerating fifty-eight 

 species, three of which are new ; and a short "Contribution to the 

 Teratology of Datura," by Prof. J. B. de Toni. 



Records of the Botanical Survey of India (vol. vi. no. 9 ; March) 

 is devoted to an enumeration, with notes and local names, of the 

 " Useful Plants in the District of Lakhimpur in Assam," by Dr. and 

 Mrs. Humphrey G. Carter, based on specimens and information col- 

 lected in 1915. 



The Correspondence of Ludwig David von Schweinitz (1780- 

 1834) and John Torrey (1796-1873), edited by C. L. Shear and Neil 

 E. Stevens, has been issued (July 16) as part 3 of vol. xvi. of the 

 Memoirs of the Torrey Botanical Club. The letters extend over a 

 period from December 1819, when Torrey began the correspondence, 

 until November 1833 — the date of the last letter to Schweinitz, who 

 died in the following February, — anl, it is needless to add, are full of 

 interesting matter, as the two botanists were, as the editors say, " the 

 two dominating figures in American botany during the early part of 

 the nineteenth century." Portraits of each are given, and brief but 

 useful biographical notices of the persons mentioned in the corre- 

 spondence are supplied in an appendix.
