THE GENUS PHOEADENDRON 341 



in the privileges which fall to their lot : the opportunity of 

 spending a year in the great herbaria of Europe, which is we 

 believe an ordinary feature in professorial life, has no counterpart 

 over here, nor would it be easy to find a university which would 

 issue as one of its publications a large and costly monograph 

 which, from its nature, is hardly likely to be remunerative. But 

 perhaps the admirable results of these opportunities, by which 

 the botanists of the world benefit, call for congratulation rather 

 than envy.

The earlier editions of this most useful work, appearing respec- 

 tively in 1900 and 1905, were duly noticed in the volumes of this 

 Journal for those years. All that was said in their praise may 

 be repeated as to the present edition, which has indeed for some 

 time _ been wanted, the delay in its preparation having been 

 "entirely due to pressure of occupation." The volume has 

 been entirely reset, so that the supplement to the second edition 

 is now incorporated in the text, to the great advantage of those 

 using the book. Dr. Jackson tells us that he has carefully 

 considered the criticisms which have come under his notice, and 

 has adopted all which could be taken up, "so far as they did 

 not contradict the plan on which this volume was drawn," but 

 he indicates that not all the criticisms have been of a useful 

 nature. He has " tried to furnish the terms in use in various 

 periods, so that a paper or book of any period can be read and 

 understood " : in this he has been successful, and we are glad 

 that he has not attempted to cut down the volume — a suggestion 

 which seems to have been made. 



The total number of terms included amounts to nearly 21,000, 

 as against about 16,000 in the second edition— "if the various 

 meanings w^ere added, they would amount to about 1,200 more." 

 The number of pages is increased from 371 to 428, but the 

 difference of paper employed has reduced the bulk of the volume 

 to a more convenient size. 



We are sorry that the publishers retain the practice — long 

 since abandoned, if ever adopted, by the best houses— of dis- 

 figuring the title-page of review copies with a die in violet ink.

This book is one of those, unhappily too rare in these days, 

 which appeal straightway to the eyes and to the touch. Neatly 

 bound in dark, smooth cloth, admirably printed, abounding from
