The present paper by Dr. Edward Lee Greene, Associate in 

 Botany in the U. S. National Museum, entitled "Landmarks 

 of Botanical History," discusses certain epochs in the develop- 

 ment of the science of botany. The subject is viewed from a 

 philosophical rather than an industrial standpoint, and the author 

 gives prominence to the biography of some of the early botanists, 

 including Theophrastus (b.c. 370-286), arid Brunfelsius, Fuchsius, 

 Tragus, and Cordus of the fifteenth and sixteenth centuries. Doc- 

 I tor Greene has in preparation further contributions on this general 



•subject.
