considerable number of primary and secondary roots bending towards it ; 

 but Lupinus albus is chemotropically positive toward solutions of di-sodic 

 phosphate. Cncurbita Pepo showed a general indifference. 



The behaviour of all the roots tested gave no indication of osmotropism. 

 Lupin roots curved away from all chemicals except the sodic salt. — G. H. 



Cherry, The. By W. J. Allen (Agr. Gaz. N.S.W. pp. 423-437, 

 May 1904). — A treatise on the culture of the Cherry in Australia, where 

 the demand for this fruit is increasing from year to year. The fruit finds 

 a ready sale, chiefly for dessert purposes. The article is dealt with under 

 the following divisions : — Stocks ; raising seedlings ; budding ; soil and 

 situation ; transplanting and distance to plant ; fertilisers ; pruning ; 

 cultivation ; picking and marketing ; diseases and varieties. It is splendidly 

 illustrated with photographic reproductions of 38 varieties, as well as a 

 coloured plate of six varieties. — H. G. C. 



Chestnut in Southern Maryland. By Raphael Low (U.S.A. 

 Dep. Agr. Bur. For., Bull. 53). — For trees, trolly, telegraph and tele- 

 phone poles, and various kinds of fences the Chestnut comes, perhaps, next 

 to the Oak in general utility. 



It shoots freely from the root, and for this reason is particularly 

 valuable in the production of coppice-wood, for which woodland com- 

 modity Southern Maryland is justly remarkable. 



The soil requirements, reproduction, coppicing, and harvesting are all 

 described in a lucid manner, while the numerous tables add much to the 

 value of the work, as do also the well-executed illustrations. — A. D. W. 



Chironia, Monograph of. By Emil Schoch (Zurich) (Beih. Bot. 

 Cent. xiv. pp. 177-242 ; with 2 plates). — Gives a complete monograph of 

 the species of this genus of Gentianacece. The distribution is very 

 carefully worked out, and full details given of the literature &c. There 

 is also some information about the anatomical characters of the genus. 

 The descriptions are very full and quite sufficient for recognition.

Chlorsea crispa. By W. B. H. (Bot. Mag. t. 7955).— Native of 

 Chile. Nat. ord. Orchidece ; tribe Neottiece. A terrestrial herb with racemes 

 of white flowers, having a nearly orbicular labellum with fimbriate 

 lamellae on the surface. — G. H. 



Chloraea incisa. By R. A. Rolfe (Orch. Bev. vol. xii. p. 158). — 

 Descriptive characteristics and other interesting particulars are given.

Chlorophyll Assimilation. By Dr. C. Bernard (Beih. Bot. Gent. 

 xvi. pp. 36-52, with two text figures). — Dr. C. Bernard, at the sugges- 

 tion of Professor King, made a series of experiments to test whether 

 assimilation is due to a ferment or enzyme produced by the protoplasm, 

 and whether it can proceed outside the living plant. His results were all 

 negative and in no way confirm Friedel and Macchiati. There is a useful 

 discussion of the literature — G. F. S.-E.
