 This article is a plea for rational education and the consequent diminution of the importance 

 of the final examination. The fundamental question is whether students are trained to think. 

 The suggestion is made that the "se?ninar" method be used more, even in undergraduate 

 courses, and that final examinations be replaced by unannounced tests during term, combined 

 with carefully checked laboratory work. — B. T. Dickson.

GENERAL, FACTORS, MEASUREMENTS 



931. Darwin, F. A phaenological study. New Phytol. 18: 287-298. 1919.— A record is 

 given of the flowering dates of 259 of the commoner plants near Brookthorpe, Gloucestershire, 

 England, for the years 1917, 1918, and 1919. Tables are also given of the mean weekly tem- 

 peratures and of the deviations from the normal. — 7. F. Lewis. 



932. Fritsch, F. E. Algal ecology. Freshwater and terrestrial forms. Jour. Ecol. 8: 

 68-76. 1920. — A review of recent contributions to the ecology of freshwater algae. Among 

 the notable papers are those by MacCaughey on Hawaiian forms (see Bot. Absts. 1, Entry 

 200), by Transeau on Spirogyra hybrids (see Bot. Absts. 2, Entry 715), by Elmore on the 

 diatoms of Devil's Lake (see Bot. Absts. 2, Entry 10), and by Chodat on some alpine species. 

 Among the forms noted are Oscillatoria, Coelastrum, Volvox, Euglena, and Hormidium. — 

 Geo. D. Fuller. 



933. Fritsch, F. E. Algal ecology. Marine forms. Jour. Ecol. 8: 66-68. 1920.— In 

 a review of some of the recent contributions to the ecology of marine algae the principal 

 points relate to the distribution of the Laminariaceae on the Pacific coast of North America 

 and about the Orkney Islands. Some data by Sauvageau (see Bot. Absts. 1, Entry 1585) 

 on the distribution and naturalization of forms occurring in the southern portion of the Bay 

 of Biscay are noted as well as an ecological discussion of the marine species of the Hawaiian 

 Archipelago by MacCaughey (see Bot. Absts. 1, Entry 200). — Geo.D. Fuller.
