The microscope and its revelations . le numberof specimens, exhibiting various ]3hases of conformation, isnecessary to demonstrate the nature of these communications;but this may be best made-out by attending to the history ofthcK development, which we shall now describe. 160. The spherical body of the young Volvox (Fig. 78, a)is composed of an aggregation of somewhat angular masses ofendochrome {It), separated by the interposition of hyalinesubstance; and the whole seems to be enclosed in a distinctlymembranous envelope, which is probably the distended hyalineinvestment of the primordial cell, within which, as will pre-sently appear, the entiie aggregation originated. In the midstof the polygonal masses of endochrome, one mass («), ratherlarger than the rest, is seen to present a circular form; andthis, as will presently appear, is the originating cell of what ishereafter to become a new sphere. The growing Yolvox atfirst increases in size, not only by the interposition of new STEUCTTJRE OF VOLVOX GLOBATOE. 281Fig.
