A word of thanks ought to be in the mouth of every user of the Flora to the Insti-tution which has placed it within their reach. None but the professional botanists willrequire it.

It is understood that Watson, who has for many years worked with Prof. Gray, and has had chargeof the Herbarium, will continue the Synopsis. It is to be hoped that at no very distantdate the final volume may be issued. i\ /\ V Iiy/^//////>, \ ^h\ ^\ ^? ^ oh--// d. ,%iV»o-
