THE INFLUENCE OF TEMPERATURE ON THE 
SOAKING OF SEEDS. 
By Franklin Kidd and Cyril West. 
(Imperial College of Science and Technology.) 
I N a previous communication (Kidd and West, 1) vve have dealt 
with the effect upon germination and upon subsequent 
development of soaking seeds of red dwarf beans (Phaseolus vulgaris 
var.) in excess of water previous to sowing. Soaking these seeds for 
periods up to 24-48 hours at ordinary room temperatures increased 
the rate and vigour of germination; but the effect under the 
conditions of the experiment upon the subsequent development of 
the plants produced was injurious, even in the case of short periods 
of soaking. 
In this communication a further fact was noted for which no 
explanation is at present forthcoming, namely, an unexpected effect 
of the temperature which obtains during the process of soaking the 
seed. We did not find as might have been expected that the
