greater value, is this, that Prof. Macoun has not depended, for the 

 determination of his plants, on his own unaided judgment, but has 

 submitted them for confirmation to some of our greatest bryological 

 specialists, such as Profs. Lesquereux and Tames, Mr. Coe. E. Austm, 

 and Drs. Kindberg, Cirl Mueller, Venturi and Warnstoff, thus making 

 assurance more assure J. Increased value is given to the work by the 

 fall and able descriptions of the new species, and by the many personal 

 notes of the author on those little points of difference that indicate close 

 observation and which are so very helpful to the student. The author is 

 to be congratulated on the thoroughness of his work. The work he had 

 set himself to do was expressed in the first sentence of the preface to 

 Part I. : " The purpose of this work is to place in the hands of Canadian 

 botanists, in a connected form, the knowledge so far obtained, of the 

 extent an 1 distribution of the Flora of Canada." This has been carried 

 out even beyond the author's first expectation, and he has presented to 

 the botanists, not only of Canada, but of the world, a work that will 

 command their respect and admiration, a work that must form the 

 basis of all future floras of Canada, and the author will be esteemed as 

 one who did his work ably and well, carrying out to the fullest the 

 Preacher's precept, "Whatsoever thy hand findeth to do, do it with 

 thy might."
