 tion during tlie seventeenth century. 



Jacob Barrelier, a Dominican, a native of Paris, wlio died 

 1673, bad carefully examined the vegetable kingdom through- 

 out the whole of the south of Europe, and made a multitude

 Linna:us. 



But the doctrine of the sex of plants, which had been ol)- 

 scurely hinted at by Grew, was exj)erimcntr.lly illustrated by 

 Jacob Bobart, and established by John Bay. liudolph Ja-
