138 MR. C. DARWIN ON THE ACTION OF SEA-WATER 



after 11 days' immersion ; one half-germinated after 14 

 days ; after 22 days all dead : many of these beans swelled 

 greatly. I tried sixty after 28 days and found all dead. 

 None survived 30 days in the cold water. 



Pisum sativum : after 11 days some germinated ; none survived 

 14 days ; none survived 30 days in the cold water. Another 

 lot of fresh seed (" Thurston's Eeliance ") all died after 12 

 days ; none survived 30 days in the cold water. I found 13 

 days' immersion in pure water killed these latter fresh peas. 

 (fNone germinated.) 



Phaseolus vulgaris (var. " early frame dwarf"): all died after 

 11 days' immersion ; after 28 days' immersion, 80 were planted, 

 but all dead. I tried another lot of fresh seed, but none of 

 them resisted even 10 days' immersion; nor did they re- 

 sist 30 days in the cold water : many of these seeds swelled 

 much (f). 



Trifolium incamatum : all died after 11 days' immersion, and 

 after 30 in the cold water. Fresh seed germinated excellently 

 after 5 days' immersion, well after 12 days, and one single 

 seed out of some hundreds germinated after 20 days. These 

 seeds swelled much. 



JJlex europceus : after 11 days germinated well ; after 14 days 

 two germinated ; after 28 days all dead. 



Lupinus polyphyllus : after 22 days, out of seven swollen seeds 

 three germinated; seven others did not swell and were all dead; 

 after 36 days' immersion one began to germinate and then died. 



Lupinus luteus (pale var.) : after 22 days / T uve( i 5 a ^ er 36 

 days' immersion -^ germinated j after 50 days all dead. 



fLupinus pubescens germinated after a month, but Mr. Berke- 

 ley says the greater number were rotten. 



Mimosa sensitiva : germinated excellently after 36 days' immer- 

 sion, and pretty well after 50 days. 



Oeum coccineum (var. splendens) : after 36 days germinated well, 

 and after 70 days one single seed germinated. 



Saxifraga incurvifolia : did not germinate after 30 days' immer- 

 sion. 



aizoides, nor did this species, but the seed was not 



very good. 



(SoLANACE^E.) 



Capsicum annuum : after 137 days' immersion, 30, out of 56 

 planted, germinated well (f).
