WOMMS, MOSS-POLYPS, SPONGES, ETC. HO 



Some idea of the vast numbers in which these 

 miimte organisms occur may be gathered from the 

 fact that an ounce of sand taken from the beach of 

 Atlantic City, despite the breakages to which the 

 minute shells were liable in being tossed and rubbed 

 about, was estimated to contain fully 18,000 indi- 

 viduals of a single species of Nonionina, and that a 

 similar measure taken from the sands of Cape May 

 yielded by computation upwards of 38,000 individ- 

 uals of the same species.
