It would be impossible for the writer to conclude without expressing 
his grateful thanks to Professor J. B. Farmer, F.R.S., for the continuous 
interest he has taken in the above investigation. The work was carried 
out at the suggestion of Professor Farmer, and but for his kindness 
in allowing the writer the use of a table in his laboratory, the research 
would have been impossible.
