IV 1N1X REDUCTION. 



tf-rra w'o<riln by western naturalists has now been brought within the limits of t<rra cognita 

 through Dr. HAYATA'S investigations. 



In accordance with the fiiots above stated and with the smthority vested in it, the Imperial 

 Academy hereby recognizes that Dr. HAYATA has made a great contribution to science and to the 

 kn twii natural resources of Japan through the study which for a score of years he has made of 

 t.ie flora of Formosa. 



The above statement put forth by the Imperial Academy is really too 

 much for me to accept for myself alone ; for I cannot forget that it is due to 

 the assistance rendered to me by all who have sympathized with me and been 

 interested in my work that I have been able to make any contribution at all 

 either to science or to my nation. As I now issue this tenth volume some- 

 what in the form of a conclusion to the series, I desire to acknowledge the 

 help so kindly given to me by so many - - teachers, relatives, friends and others 

 - who, one and all, have helped forward the work which has brought me the 

 honour of being awarded the Prince KATSTIBA Commemoration Prize. To 

 them are due my most heartfelt thanks of Avhich I beg them to accept tliis 

 expression. To one unknown friend I owe the following letter by which I am 

 profoundly touched. He wrote : " I shall take it for granted tint you have 

 no reason to accept a word of congratulation from a humble follow whose 

 name has probably slipped from your memory. For my part, however, 

 nothing would gratify me so much as to have you know that there is a poor 

 creature who under his humble roof rejoices at your success." Who tlu writer 

 may be I do not know, but somehow the letter recalls my mother who is 

 at rest, and it is hard to restrain the tears. 



In token of my gratitude to all my Mends, I have decided to give the 

 whole sum which accompanies the Prize (eu 1,000) for the promotion of 

 science, one half to the Tok} r o Botanical Society and the other half to the 

 Forniosan Natural History Society. 



In conclusion, I avail myself of this opportunity to tender my hearty 

 thanks to the officials of the Government of Formosa, to whom I am much 

 indebted for help in the collection of material and in the publication of this 

 work.
