I find by experiment that the average volume of rather a large walnut is a little less than 16cc., of a hazel nut 2.6cc. Perhaps that authors meant to say "looked the size of a hazel nut" etc.' [Published in the 'Proceedings of the Royal Society of London' B, 1933] Endorsed on verso as received 13 May 1933. 12 May 1933
