1}. On Fermentation ; by P. ScuttzenspEerGeER. [International 
Scientific Series. D, Appleton & Co., New York.|—This volume, 
although rather too technical for the general reader, gives to the 
student in a convenient form a résumé of the early and of the most 
€ most serious error is, perhaps, the translation of “ matieres 
hydrocarbonées” by “hydrocarbons.” On page 65 and following, 
and throughout the book sugar, cellulose and starch are spoken of 
as “hydrocarbons!” A mistake scarcely less serious occurs in 
the description of Schiitzenberger’s process for determining dis- 
solved oxygen (pages 108 and following). Here Schiitzenberger’s 
“hydrosulphurous acid” and “ hydrosulphite” are rendered, very 
properly, “hyposulphurous” and “ hyposulphite,” but no note or 
comment (except the symbol) tells us that the sodium hyposul- 
phite thus indicated is not the common “ hyposulphite of soda 
which still in the arts and indeed generally bears the old name. 
On other pages hyposulphite is used in its former sense (instead 
of “thiosulphate” or other name). It would therefore seem that 
the mistake arose from ignorance or carelessness on the part of 
the translator. : 
Among other less important blunders it may be said that
