fats, oils, waxes, and phosphatides; II (116 pp.) to carbohydrates; III (23 pp.) 
to glucosides; IV (41 pp.) to tannins; V (30 pp.) to pigments; VI (19 pp.) to 
nitrogen bases; VII (17 pp.) to colloids; VIII (42 pp.) to proteins; and IX (68 
pp.) to enzymes. The book is especially written for plant physiologists, and 
apparently gives the several subjects their proper proportional consideration 
as demanded by the aim. It is a very simple, direct statement of the cardinal 
facts of the subject, giving the main methods, chemical and microchemical, 
used in the field. The avoidance of a technical form of presentation makes 
the work usable by those of slight chemical training. In discussing chlorophyll, 
the authors make the barest mention of the older work on the subject, done, 
as they say, in the main with impure products. The discussion is based on the 
fate work of WILLSTATTER and his students, and of Tswetr. This gives in 
the simplest and most direct way the picture of our present knowledge of chloro- 
phyll. The treatment of chlorophyll is typical of the method of the book and 
shows one of its great virtues. No mention is made of the important work of 
Iwanow on metabolism of fats, but this could hardly be expected, since the 
book deals with little literature of a Jater date than 1910, The treatise is One 
that every plant physiologist and probably every botanist dealing at all with 
the physiology of plants will want on his desk.—W1tL1AM CROCKER. 
MINOR NOTICES 
Nigerian plants.—The British Museum has publisheds a catalogue of the 
plants of the Oban District of South Nigeria collected by Mr. and Mrs. P.. 
Amaury Tatgor during 1909 to 1912. The determinations have been made 
by several specialists, and the collection has proved to be unusually rich in 
novelties. Of the 1016 species and varieties enumerated, 195 are new, and 
among, them are 9 new genera, as follows: Alphonseopsis and Denneltia 
(Anonaceae), Crateranthus (Myrtaceae), Afrohamelia, Dorothea, Diplosporop- 
sis, and Globulostylis (Rubiaceae), Scyphostrychnos (Loganiaceae), T: albotie 
(Acanthaceae), ‘and Amauriella (Araceae). The new species are distributed 
among 31 families, those receiving the largest additions being Rubiaceae (34); 
Acanthaceae (21), Orchidaceae (20), and Apocynaceae (12).—J. M
