numerous illustrations, The opening paragraph of § 49 may be taken as a 
fairexample of general “interpretation.” For instances of alteration take 
these two: ‘‘unvollkommenen Bundeln” of mosses (p. 197) is rendered 
“rudimentary vascular bundles (p. 216). Pfeffer would probably deny the 
morphological implication in the latter phrase; at least he had avoided it in 
his use of the original adjective. Again: “nachweisbaren Producten” of 
photosynthesis (p. 299) are not necessarily “visible products” (p. 317), and 
the change makes the sentence untrue. Nor will it be fair to consider the 
passage of the English proofs through Pfeffer’s hands as equivalent to an 
endorsement of the translator’s particular modes of expression. 
The comparison with the original is necessitated further by the avowed 
changes which Dr. Ewart has wisely introduced. In the main these are indi- 
cated by brackets, but this should have been uniformly done. The later 
literature is cited and other betterments are noticeable. The avoidance of 
new terms is desirable whenever it does not involve too great circumlocution, 
and the new book has practically none. We note, however, the increased 
use of photosynthesis, which is making its way in spite of conservatism, 
though it is not used consistently. Ewart is in error regarding the term 
photosyntax (footnote, p. 302), which he rejects as unnecessary. It was. 
defined by the proponent precisely as photosynthesis (p. 292), and could by 
ho means include “all cases of carbon dioxide assimilation.” 
Some of the slips of the German text have been corrected, but two notable : 
ones in § 4o have been missed. On p. 250 the amount of water transpired 
under favorable conditions is given as I to 10% per 24 hours “from a single 
Square centimeter of leaf surface.’ This should read decimeter, the amounts 
named being 100 times too large. On p. 251 also the last two sentences of 
the middle paragraph should be transposed, the last one being meaningless. 
in its present position. : 
Inasmuch as the cross-references are to sections it would have been con- 
venient to have the section numbers in the page head, as in the German book. 
This disadvantage is much more than balanced, however, by the very com- 
plete index, an essential feature absent from the original. 
The second volume is awaited with the greatest interest, and we trust the 
English version will appear promptly as promised. And we must not , 
any differences of opinion or defects in the translation to minify our obligations. 
to Professor Ewart and to the Clarendon Press for the helpful and elegant 
volumes.—C, R. B.
