380. Bancroft, W. D. [Rev. of: Slosson, E. E. Creative chemistry. 20 X H cm., 

 X + Sll p. The Century Co.: New York, 1919.] Jour. Phys. Chem. 24:329-331. 1920.— 

 The book contains a great deal of unusual information concerning plant products, their uses, 

 and the direct and indirect influences of war upon agriculture. "One is continually running 

 across unsuspected information, as, for instance, that the red rubber sponge and eraser tips 

 for pencils may be made from a gum extracted from the corn germ. There are relatively few 

 mistakes," and "in spite of occasional defects the book is an extremely valuable one." —

 1921. — By-products of Brassica spp., such as cabbage stalks and petioles, petioles of turnips 

 and rutabagas, contain considerable sugar which might be utilized. Other possible sources 

 are sugar in rhizomes of couch grass {Agropyron repens) and in the uni-internodal corms of 

 the bulbous oat-grass (Arr/ienaf/ierww ai^enacei/m), starch in rhizome of bracken-fern (Pieri's 

 aquilina), and inulin in roots of spear thistle {Car dims lanceolatus) . — 0. A. Stevens.

 180 fig. Parey: Berlin, 1917.] Leopoldina 54: 42-44. 1918. — The reviewer recommends 

 Maurizio's work highly, not only on account of its exhaustive treatment of grains from all 

 points of view, but also on account of its avoidance, so far as possible, of technicalities. — 

 A. W. Evans.
