Plant nauseously fetid, and incrusted more or less with calca- 

 reous earth, which is not accidental, as many have supposed, 

 but an essential and integral part of its constitution. Dr 

 BREWSTER has ascertained that each group or mass of the 

 calcareous matter is held to the stem of the plant by a very 

 fine transparent membrane ; and that the minute particles 

 of which each group consists, possess double refraction, 

 and have regular neutral and depolarizing axes. He also 

 found that the plants were phosphorescent when laid upon 

 heated iron, so as to display their entire outlines in the 

 dark.
