 of the Imperial Department of Agriculture in the 

 West Indies. (West Ind. Bull. XL 4. p. 315—350. 1911.) 



In addition to a chronological account of the work carried out, 

 a füll bibliography of relevent literature is given, together with a 

 list, elassified aecording to crops, of the fungus-diseases which have 

 been dealt with. A. D. Cotton. 



Harden, A. and S. G. Paine. Action of dissolved Substan- 

 ces upon Autofermentation of Yeast. (Proc. Roy. Soc. 

 London B. LXXXIV. p. 448-459. 1912.) 



The author's summary is as under: 



All dissolved substances which Plasmolyse the yeast-cell also 

 cause a large increase in the rate of autofermentation. Substances 

 such as urea, which even in concentrated Solution do not produce 

 plasmolysis have no accelerating effect. Toluene produces a similar 

 effect to concentrated salt Solutions. 



The effect produced by salts is probably a direct result of the 

 concentration of the cell contents due to plasmotysis , bat in the 

 case of toluene it is possible that some other factor (such as disor- 

 ganisation of the cell or hormone action) is concerned.

Petch, T., Revisions of Ceylon Fungi. Part III. (Ann. Roy. 

 Bot. Gard. Peradeniya. V. 4. p. 265—301. Aug. 1912.) 



The author continues his critical observations on Ceylon fungi, 

 supplimenting and revising the original descriptions of Berkeley 

 by a study of fresh material and comparisons with the type speci- 

 mens. The present series Covers a wide ränge (practically all groups 

 of fungi), and is indispensable to all workers in tropical mycology.

A list with descriptions and notes on the members of the 

 Saprolegniaceae and Leptomitaceae of Nova Scotia. One new spe-

This volume completes the Lichen-Flora commenced by Crombie 

 in 1894. It is illustrated by 59 plates. A very large number of spe- 

 cies has been transferred from old and recognised genera, to places 

 in other genera. In many cases too, more modern specific names 

 have been replaced by older ones in aecordance with the interna- 

 tional nomenclature rules. 0. V. Darbishire (Bristol).
