great variation in the production of oil, but in recent years the 

 amount has run up very largely, and while it amounted to 34,000 

 barrels in 1886, it has become 257,000 in 1894, although it is 

 remarked that this production is small in comparison to that of 

 Baku or of the United States. 



4. A Text-book of Entomology ; by A. S. Packard ; pp. xvii-f- 

 729, 8vo, 1 pi. and 654 figs, in text. New York, 1898 (The 

 Macmillan Company; $4.50). — This, the latest of Prof. Packard's 

 books on insects, occupies a comparatively new and increasingly 

 important field among modern text-books of entomology. After 

 a brief discussion of the relations of insects to other arthropods 

 and the rest of the animal kingdom, the work is entirely devoted 

 to anatomy, physiology, embryology and metamorphoses. Much 

 the larger portion of the work is given up to the first of the three 

 parts into which it is divided, that on external and internal anat- 

 omy, in which some account is given of the physiology of the 

 more important organs, especially those involved in locomotion. 

 The second part, on embryology, follows closely Korschelt and 

 Heider's excellent text-book on the embryology of invertebrates, 

 but the account of the maturation and fertilization of the egg is 

 so brief and imperfect that it gives little idea of these processes. 

 A more noteworthy defect is the apparent omission of any 

 description of asexual reproduction, although the parthenoge- 

 netic eggs of Cecidomyia are described and figured. The final 

 part, on metamorphoses, is naturally the most interesting part of 

 the book and cannot fail to be of service to the general student of 

 biology. The volume, which is well and profusely illustrated 

 and admirably printed, will be appreciated by every one interested 

 in entomology.
