Recording Apparatus for the Study of Transpira- 

 tion of Plants : Albert F. Woods. Mr. Woods 

 has adapted Marvin's recording rain gauge, with 

 the assistance of Prof. Marvin, to recording con-

 is a new genus with a single species, M. paradoxa. 

 Not only descriptions but life histories of these 

 plants are given, accompanied by a handsome 

 plate.

 illustrate the paper.
