The seeds must be soaked a certain number of hours before they 

 ripen sufficiently to give off their full blaze-current; dried peas require 

 at least twelve hours' soaking. 



An average blaze-current of '03 or '04 volt indicates a high-class pea

of which 97 per cent, would germinate; individual peas out of the 

 series tested would give '07 or '09 volt ; others only '01 or '02 volt. 



The electrical test is much quicker than the germination test. If 

 we find we can work rapidly enough, the method may be of use to the 

 seed merchant who needs to know as quickly as possible the value 

 of seeds in the market. 



We are still engaged in making a long series of tests on different 

 varieties of seeds. 



The Structure and Function of the Mammalian Heart. — Report 

 of the Committee, conMsting of Professor C. S. Sherring- 

 ton (Chairman), Professor Stanley Kent (Secretary), and 

 Dr. Florence Buchanan, appointed to make further Re- 

 searches thereon. (Drawn up hy the Secretary.) 



The original Committee consisted of Professor Francis Gotch, Chair- 

 man, and Professor Stanley Kent, Secretary. This Committee was 

 deprived of its Chairman by the death of Professor Gotch. Professor 

 Sherrington was appointed to take his place. Dr. Florence Buchanan 

 was added to the Committee at the annual meeting of the Association 

 in 1914. 



The following Report consists of two parts. The first part deals 

 with the work of the Committee for the year 1913-14. This was 

 delayed last year owing to the fact that the Association met in Australia.
