678. Brunnhofer, A. von. Verwaltungsrecht und Holzhandel — zwei Vorlesungen die 

 an der Schweizer. Techn. Hochschule gehalten werden sollten. [Administration and timber 

 sales — two subjects that should be taught in the colleges of Switzerland.] Schweiz. Zeitschr. 

 Forstw. 72 : 142-146. 1921. — The timber sale policy should be placed on a uniform basis, espe- 

 cially stumpage prices. At present, each community sells to its own advantage at the 

 expense of the general market. Strong courses in these subjects would create a uniform 

 method and bring about application. Courses should be strengthened in practical road 

 building, special chemistry, soil studies, bacteriology, geology, field excursions, and practical 

 forestry. — J . V. Hofmann.

 General botany for universities and colleges, xii + 459 p. ; Laboratory and field exercises for 

 general botany, viii + 199 p. Ginn and Co. : Boston and London, 1920.] Nature 107: 6^70. 

 1921. — The reviewer finds the text lacking in continuity and balance. "Figure 146, which 

 purports to be Amanita muscaria, is clearly a Coprinus." The section on seasonal life of 

 certain common plants is a good feature. [See also Bot. Absts. 9, Entry 673.] — 0. A. Stevens. 



680. Gager, C. Stuart. Tenth annual report of the Brooklyn Botanic Garden, 1920. 

 Brooklyn Bot. Gard. Rec. 10: 23-81. 1921. — The report contains a r^sum^ of the 1st decade 

 of the Botanic Garden, as well as data for 1920. Reports of heads of departments, and a 

 financial statement are included; also a bibliography of publications of members of the staff, 

 and, as Appendix 6, the Agreement between the Ecological Society of America and the Brook- 

 lyn Botanic Garden concerning the publication of the journal. Ecology. — C. S. Gager.

 cultural students. Vol. I. 235 p. University Press: Cambridge, 1920. — Laboratory exer- 

 cises are given with blank pages for notes interleaved. Vol. I is intended to cover the Ist 

 year's course on the chemistry and physics of the soil; it comprises 43 chapters and an ap- 

 pendix of tables of constants and analyses. Volumes II and III are announced to follow. —

 tiques du Bacille diphterique. [Intravital staining of the metachromatic corpuscles of the 

 Bacillus of diphtheria.] Compt. Rend. Soc. Biol. Paris 83: 267-269. 1920.— The granules of 

 Corynebacterium diphtheriae react as metachromatic bodies when sufficient Nile Blue to give 

 a barely perceptible tint is added to a hanging drop culture. The bodies of the bacterial 

 cell are stained light blue and the granules rose colored or mauve or violet in 5-15 minutes. 

 The bacteria remain alive in this dilute stain for many hours and appear normal. — E. A.
