of the extract, and are not compounds with magnesia or any other

Edestin, ,, ,, Hemp-seed, Cannabis sativa (416, 302). 



Avenalin, ,, ,, ,, Oat, Avena sativa (299, 324). 



Castanin, found in the seeds of European chestnut, Castanea vulgaris (24). 



Maysin, ,, Maize, Zea mays (308). 



Tuberin, tubers of Potato, Solanum tuberosum (586, 322). 



Globulins have also been isolated in considerable quantity from 

 the following seeds and have been the subject of more or less study, 

 but distinctive names have not yet been given to them. 



Globulin, Crystalline, from Flax-seed, Linum usitatissimum (301). 



,, Squash-seed, Cucurbita maxima (143, 302). 



Castor-bean, Ricinus communis (416, 302). 



,, Cocoa-nut, Cocos nucifera (415, 189). 



Sesame-seed, Sesamum indicum (416). 



,, Cotton-seed, Gossypium herbaceum (367). 



Sunflower-seed, Helianthus annuus (415, 327). 



,, Candle-nut, Aleurites triloba (418). 



Radish-seed, Raphanus sativus (418). 



,, Pea-nut, Arachis hypogea (415). 



Rape-seed, Brassica campestris (570). 



,, Mustard-seed, Brassica alba (570). 



Globulins which have not yet been named have also been isolated in 

 small quantity from the seeds of wheat, Triticum vulgar e (366, 88) ; rye, 

 Secale cereale (304) ; barley, Hordeum vulgare (305) ; rice, Oryza sativa 

 (439) ; and maize, Zea mays (72, 308, 570), and in larger amount from 

 those of the oat, Avena sativa (299, 300, 570). In the wheat-kernel 

 most, if not all, of the globulin is contained in the embryo (297, 336), 

 and, from analogy, it is probable that most of it occurs in this part of 

 the seeds of the other cereals except in those of oats, in which the 

 quantity is relatively so great that it is probable that, in this seed, it 

 forms a part of the reserve protein.
