STUDIES IN SEEDS AND FRUITS 



Table illustrating the Effect of Hairs on the proportional 

 Weight of the Seed-coats in Resting Seeds. 



* The proportional weight of the hairs was alone ascertained. 



t In Gossypium {hirsutum ?) the cotton adheres firmly to the black seed, becoming 

 dirty grey and matted next to the seed. Of the relative weight of the hairy covering 

 (43-5 per cent.), white cotton forms 37 'i and the grey matted portion 6-4. 



In G. barbadense the cotton easily separates from the black seed, there being no 

 adherent covering of matted hairs.
