EVERGREEN TREES IN WINTER. . 347 



Miyoslii I wish to offer my heartiest thanks for their kind 

 advice during the progress of my work in the laboratory of 

 the Botanical Institute belonging to the College of Science. 

 I am also indebted to Mr. K. Nakamura, Director of the 

 Central Meteorological Observatory in Tokyo, for his kind per- 

 mission to use the climatological tables made in the Observatory 

 there, and to all other friends who have kindly assisted me in 

 various ways. 



July 1899.
