AS the rushing comets dim the brightest luminaries 

 with their radiance, so the ocean meteors, the moving 

 medusae, seem to excel in the glory of their light. 

 . The sea-jellies are among the commonest forms of the sear 

 shore. In the summer months the silvery sands are strewn 

 Vith their glassy disks ; unattractive then, but, once launched 

 and imbued with life, possessed of many beauties of form and 

 color. They range in size from those almost invisible to the 

 naked eye, to giants weighing, it is estimated, over a ton. 

 Many have a complicated structure; yet, in nearly all, the 

 solid parts of the animal rarely represents over five per cent 

 of the whole ; and in specimens of a familiar northern kind, 

 Aurelia, 95.84 is water. Little opportunity for light in such 

 a creature, one would say ; yet the simple jellies are num-
