358 HISTORY OF BRITISH ZOOPHYTES. 



" Earth has not a plain 

 So boundless or so beautiful as thine ; 

 The eagle's vision cannot take it in ; 

 The lightning's glance, too weak to sweep its space, 

 Sinks half-way o'er it like a wearied bird : 

 It is the mirror of the stars, where all 

 Their hosts within the concave firmament. 

 Gay marching to the music of the spheres, 

 Can see themselves at once." — CatnpbelL

 site cells : cells immersed, coalescent, horizontal to the plane of 

 the axis, opening on both surfaces in quincuncial pores, protected 

 with an operculum. — Johnston.
