been touched, and yet it will yield most valuable results. There are also 
the phenomena connected with the growth and development of each indi- 
vidual form—perhaps the most interesting portion of the subject. Every 
species has a history of its own—always suggestive and full of interest— 
but in too many cases the historian is yet to be found. There is its birth ; 
its first transient wandering existence ; later, its adult life—whether a 
in the sand of the sea bottom or anchored by cables capable of resisting the 
heaviest surf—whether boring deep in submerged timber or excavating 
chambers in the hardest stone—now, as the Oyster, immovably bound to 
the exposed rock, or, as the Fusus, crawling slowly over it—now darting 
rapidly through the water, or floating on its surface, the sport of every 
wind and tide; there is its food—its means of obtaining it—its special 
habitat—its relations to the species immediately surrounding it—its 
economic value to man. All these are chapters in the life-history of every 
species, and chapters which in many instances are yet to be written. The 
table of contents is indeed prepared; but the contents themgelves—the 
material which is to give the work its real value—still remains to be filled 
in.
