Longevity of Seeds. 3 



The fii'st column gives the name of the seed, the second the 

 age in years, the third the number of seeds tested^-, the fourth 

 the percentage germinating (which in nearly all previous records 

 is omitted!), and the fifth the author making the obserA^ation 

 and any remarks as to treatment. If no author's name is given 

 the observation is original. To save frequent footnotes, a 

 reference list of the chief works consulted is appended beneath.

1 Where the number is marked with .an asterisk (*), this is the original percentage ger- 

 mination of the fresh seed ; but, if the percentage is 100, this means either that all the 

 seeds originally were germinable, or tliat the number in the next column has been 

 calculated on the basis of a 100 per cent, germination in the original seed, and gives the 

 percentage of originally germinable seeds remaining germinable.
