1028 EXPERIMENT STATION RECORD. 



Concerning the mineral content of normal and stunted kohl-rabi plants, J. 

 Xawodxy (Ztschr. Naturw. [Jena'], 70(1898), No. 3, pp. 184-188). 



Concerning the substitution of arsenic acid for phosphoric acid in the nutri- 

 tion of plants, J. Stoki.asa (Ann. Agron., 23 (1897). No. 10, pp. 471-477). — From 

 experiments with oats the author concludes that while arsenic acid can not replace 

 phosphoric acid in the living cell, it is able to induce the formation of furfurol 

 derivatives, and consequently to increase the development of the organs of assimila- 

 tion in the plant. 



Concerning the growth of root hairs and rhizoids, A. Sokolowa (Bui. Soc. Imp. 

 Nat. Moscow, 1897, No. 2, pp. 167-277, pis. 3). 



Concerning the roots of Sorghum saccharatum, J. Zawodny (Ztschr. Naturw. 

 [Jena], 70 (1S9S), No. 3, pp. 169-183). 



The regeneration of injured roots, G. Lopriore (Abhandl. K. Leopold. Carotin. 

 Dent. AJcad. Natnrf., 66 (1896), No. 3, pis. 8; abs. in Bot. Cental., 73 (1898), No. 8, pp. 276, 

 277). — Treats of the repair of tissues that have been injured by splitting the roots 

 of a number of plants. 



Transition tissue, its origin and function in gymnospermous plants, W. C. 

 Worsdell (Trans. Linn. Soc. Bot. [London], 2. ser., 5, No. 8, pp. 301-309, pis. 4). 



The formation of cane sugar from dextrose in the vegetable cell, J. GRUSS 

 (Ber. Dent. Bot. Gesell., 16 (1898), No. l,pp. 17-20). — A preliminary paper in which the 

 author claims that cane sugar can he formed from dextrose in the cell, and that cel- 

 lulose and starch are formed from cane sugar. In the formation of starch and cellu- 

 lose no aldehyde groups were set free. 



On the present status of the Nitragin question, J. .Stoklasa (Ztschr. Landw. 

 Versuchic. Oesterr., 1 (1808), No. l,pp. 7S-SS). 



Concerning the conformity of the propagation of plants and animals, V. 

 Hacker (Biol. Cental, 17 (1897), Nos. 19, 20; abs. in Bot. Centbl, Beihefte, 7 (1897), No. 5, 

 pp. 340-343). 



The toxic action of phenols on living plants, R. H. True and C. G. HuNKED 

 (Proc. Amcr. Pliarm. Assoc, 45 (1897), pp. 252-260). 



On the poisonous action of copper on various plauts, M. Miyajima (Bot. Mar/. 

 [Tokyo], 9 (1897), No. 130, pp. 417-427). 



The accommodation of plants to hot and cold climates, J. Costaxtix (Hid. 

 Sci. France et Belg., SI (1897), pp. 489-511). 



Lessons with plants, L. H. Bailey (New York: The Macmillan Co., 1898, pp. 491, 

 jigs. 446). — This consists of popular suggestions for seeing and interpreting some of 

 the common forms of vegetation. It is a valuable contribution to the nature studies 

 for primary and secondary schools. 



FERMENTATION— BACTERIOLOGY. 



The occurrence of alcoholic ferments in nature and their trans- 

 portation, A. Berlese (h'ir. Fatal. Veg., 5, pp. 211, 295, 354; aba. in 

 Cental Bait. u. Par., 2. AM., 3 {1897), No. 21-22, pp. 592-597).— The 

 author reports the results of investigations of soil from vineyards and 

 from neighboring woods; bark from grapevines and from trees; leaves, 

 flowers, fruit, etc., of the grape and other plants; insects, small animals. 

 and the air, for the presence of the ferments so necessary to wine 

 making. The organisms of alcoholic fermention were quite commonly 

 found, although their occurrence was noticed at different times for differ- 

 ent hosts. In April and June, Saccharomyces apiculatus, 8. ellipsoideus, 

 S.pastearianxs, forms of Torulopsis, Mucor dematium. etc., were found
