With the exception of the last-named plant, which belongs to the Euphorbiaceae and 

 has albuminous seeds, all are leguminous and have ejcalbuminous seeds. 



The time occupied in attaining the maximum weight was the time required for ger- 

 mination, as indicated in the "maximum weight" column. 



These experiments should be of interest to the agriculturist. At 

 the time they were made I was not aware that Professor Ewart had 

 several years before experimented upon the effect of previous swellings 

 and drying on the germinative capacity of Peas {Pisum sativum). The 

 seeds were well soaked in water and then slowly air-dried. After the 

 first soaking and drying they all germinated. After the second 

 soaking and drying only 40 per cent, germinated when the integuments 

 were entire, but all germinated when the integuments were broken. 

 Seeds subjected to a third soaking and drying failed to germinate 

 whether the coats were entire or broken [Trans. Liverpool Biol. Soc, 

 1894, viii. 207).
