RADIOLARIA. 
Radiolaria are living creatures, ranging in diameter from the tenth to the one hundred and fiftieth part of an inch, of complicated structure, 
though they are classed among the lowest forms of life. The skeletons are of exquisite construction, and with the exception of one group 
are composed of translucent flint. Nearly all Radiolaria are capable of emitting a phosphorescent glow. The tiny spheres shewn in the body 
of the creatures serve as stores for nutriment and water chambers for locomotive purposes, and are as well luminous organs. The radiating 
feelers attract food particles.
