RESULTS OF SIMULTANEOUS EXPOSURE FOR TWO HOURS TO A TEMPER- 

 ATURE OF I OO TO 110 C. OF ENTIRE SEEDS OF ENTADA SCANDENS AND 



GUILANDINA BONDUCELLA, ILLUSTRATING THE POWERS OF RESISTING 

 HEAT IN THEIR SHELLS OR COVERINGS POSSESSED BY IMPERMEABLE 

 SEEDS, AS COMPARED WITH THE BEHAVIOUR OF THE SEEDS OF THE 

 SAME SPECIES EXPOSED TO THE SAME TEMPERATURE, BUT IN A 

 BROKEN CONDITION, AND THEREFORE NO LONGER PROTECTED BY 

 THEIR SHELLS. 



(The results are stated in percentages, the materials tested being 2 entire seeds of 

 Entada scandens weighing in all 861 '3 grains, and 3 entire seeds of Guilandina bonducella 

 weighing io6'8 grains. The data given for the seeds in their broken condition represent 

 the average of a number of experiments made in other connections during the course of 

 this investigation. )

1 1 -4 and 8-0 per cent, respectively. This was more than 

 regained after an exposure of some days to the air, there being 

 a final excess over the original weight of 4*6 per cent, in the 

 case of Entada scandens and of 11*5 per cent, in the case of 

 Guilandina bonducella. 



Unfortunately, all the seeds failed to germinate, though
