OUR SEA-ANEMONES. 
BY A. E. VERRILL. \ 
To all frequenters of the sea-shore during the summer 
months who take pleasure in seeking and studying the many 
Wonderful and beautiful inhabitants of the ocean, the modest 
and retiring Sea-anemones cannot fail to offer many attrac- 
tions; and there are few marine creatures that can so easily 
be reconciled to the narrow limits of an aquarium, and so 
readily become permanently established in their new home. 
Thus they afford us every opportunity to study their habits 
and structure, and to watch their ever-varying forms and 
utiful colors. But to see them in their perfection one 
must visit them in their native haunts in some cool, rocky 
Pool, overhung with projecting ledges and drooping sea- 
T Tes or in some deep grotto among the shattered cliffs, 
= half-itlumined by the sunbeams which struggle for entrance
