 standing their minuteness^ their figure is well defined, 

 and they are made black or blue by iodine^ proving that 

 they are as much starch as the larger globules, and 

 differing from them in nothing but size. These spherules 

 may be either free in their starch-cells or conglomerated 

 and joined together in pairs or threes, producing dumb- 

 bell or somewhat triangular forms. Sometimes they are 

 ■'^'-m found with shreds of membrane, and at others are in- 

 vested more or less by an utricle. In the starch-cells 

 ed with GlokkrL. more remote the granules are larger and fewer, so that 



their increase in size is attended with a diminution in 

 number, showing most clearly that the largest are the
