The Physiology of Nematocysts 



3^7 



a breaking down of the surface of the tentacles or acontia when 

 exposed to certain media, or in some cases to contraction. All of 

 the experiments were repeated several times, and some, many 

 times, so that the reports are based on the behavior of thousands 

 of nematocvsts.
