60° 0, for about the same time, and finally at 100° C. for almost an hour. This 

 does not kill the peas, as has been shown by H. H. Dixon,' and was tested 

 by germination in the sample used. Some of the beans are killed by the 

 procedure, but some germinate. Dead seeds were obtained by exposing 

 living seeds to a saturated solution of chloroform in water, and tlien drying. 

 None of the seeds thus treated germinated. Below are given the maximum 

 weights and salient figures in the series of experiments. Time- weight 

 curves are given, showing the variation under the diverse conditions ; these 

 were constructed from data obtained by weighing the seeds, dried on the 

 outside by bibulous paper. To prevent evaporation the weighing was made 

 in a weighing-bottle.
