Concluding remarks, 



The "Flora of Koh Chang", publication of which was commenced 

 in the year 1900 (with Part I), is now, with the present issue of 

 Part X, brought to a close. 



The first eight parts appeared in the course of a few years 

 (1900 — 1904), after which, however, five years elapsed before the 

 issue of Part IX, and a further period of years before the present 

 concluding part was ready for print. This delay, due to circum- 

 stances beyond my control, I very much regret. 



Of the botanical collections brought home, all, save for a single 

 group, have now been worked up. The exception is that of the 

 perforating algæ, the investigation of which, entrusted to the care 

 of M. Maurice Gomont of Paris, was brought to a standstill upon 

 his decease.
