in college, it seems to me perhaps as good an 

 epitome as we possess, within so narrow limits, 

 of the facts and principles of organic evolution.

Produits aromatiques artificiels et naturels. By 

 Georges F. .lAtrBERT, Docteur es Sciences, 

 ancien Preparateur de Chimie &, I'Ecole Poly- 

 technique. (Encyclopedia scientifique des 

 Aide-Memoire.) Petit in-8. Pages 169. 

 This is the sequel to the author's previous 

 book ' Matieres odorantes artificielles ' (re- 

 viewed in this Journal, XI., 710), and re- 

 sembles it closely in all respects. The former 

 volume contained the nitro and halogen deriva- 

 tives, phenols, and aldehydes ; while, in the 

 present one, the remaining odoriferous sub- 

 stances are grouped in the following chapters : 



I. Aromatic alcohols (34 listed). 

 II. Aromatic acids and their derivatives (70 listed). 



III. Terpenes (22 listed). 



IV. Camphors (20 listed). 



V. Terpene alcohols, aldehydes, and acids (10 

 listed). This includes such compounds as geraniol, 

 citral and ionone, but no terpene acids are mentioned. 



There are in all 169 pages — 41 pages of text 

 (including the Preface), 121 pages of tables, and 

 7 pages of index. 



No one could guess from the title just what 

 might be the scope of this book, and most 

 chemists, even after a careful examination, will 

 still be in doubt as to what the author is en- 

 deavoring to tabulate, for many of the com- 

 pounds listed are ' aromatic ' only to the extent 

 of containing a benzene nucleus and have not 

 the remotest interest in perfumery, although 

 the author's idea of a perfume seems to be differ- 

 ent from that of most chemists, since he says 

 on page 48 : " Les acides benzoique et cinna- 

 mique sont & I'etat pur des parfums puissants. " 



The column in the tables headed ' Literature 

 and Patents ' is unsatisfactory, being either 

 meagre and not up to date, or else merely a 

 reference to some larger work and not to the 

 original article at all ; while, in spite of the 

 heading, not a single patent reference is given 

 in the entire book. 



By endeavoring to expand to two volumes 

 what could much better have been given in one, 

 the author has been forced to introduce a large 



amount of wholly extraneous material, and has 

 thus completely defeated the main object of 

 memory aid, which is to present the important 

 facts concisely and entirely free from all that is 

 either irrelevant or of only remote interest.

The Compendious Manual of Qualitative Chemical 

 Analysis of C. W. Eliot and F. H. Storer, 

 as revised by W. E. Nichols. Nineteenth 

 edition, newly revised by W. B. Lindsay, 

 Professor of general and analytical chemistry 

 in Dickinson College, and F. H. Storer, Pro- 

 fessor of agricultural chemistry in Harvard 

 University. New York, D. van Nostrand Co. 

 1899. Pp. 202. Price, $1.25. 

 It is now over thirty years since the first 

 edition of this book was published, and through- 

 out this time it has held its place as one of the 

 best simple manuals. The present edition is 

 thoroughly modern and satisfactory. It is the 

 avowed scheme of the editors to give but one 

 method for each separation, and considering 

 the elementary nature of the book their choice 

 of methods must be commended. In its pres- 

 ent form ' Eliot and Storer ' will maintain its 

 past reputation. ^ Renouf.

The first volume of this book was reviewed 

 in Science, Vol. IX., p. 729. The praise given 

 to the first volume should be extended to the 

 second. One needs merely to open the volume 

 at random and read, to recognize the merits of 

 the book. The chapters on diazo compounds, 

 on azines, on terpenes, on quinones are notable 

 examples of thoroughness, and of the amount 

 of recent research often condensed into a few 

 lines. 



It must be noted that this is not a book for
