195 



groups under their respective heads, in the various divisional 

 chapters of the boolis which they constitute, vihile the minor 

 groups below orders are treated under sections of these cliapters 

 with more or less detail. 



Mr. Kirby, being an Englishman and a member of the British 

 Museum staff, it is no more than natural that in his volume he 

 has given British entomology especial consideration, but in so 

 doing he has hardly impaired its value for a text-book to the sci- 

 ence of the entire subject. Indeed, the American entomologist's 

 library will be lacking a most useful auxiliary to monograpliic 

 treatises unless possessed of a copy of this manual. Of all the 

 species making up his seven orders, he states that no less than 

 12,600 are to be found in Britain, as compared with the 270,000 

 making up the insect fauna of the world. We see the book's 

 greatest weakness in his introduction, where not sufEoient atten- 

 tion has been given to the anatomy of insects, their study from a 

 general standpoint, their distribution in time, their taxonomy and 

 similar matters, all of which give the works of Packard such a 

 peculiar value. Not a single cut illustrates the fourteen pages 

 devoted to his introduction in a volume of nearly three hundred. 

 On the other hand, it would be hard to accord too much praise to 

 the 650 figures contained on 87 plates that embellish the book. 

 To the general student, as a means of diagnosis of the main 

 groups, they must prove of the very greatest assistance, portrayed 

 as they are with marked accuracy, strength, and clearness. For 

 the purpose mentioned, the Coleoptera are especially good, bold, 

 and well drawn, though perhaps lacking in that refinement of 

 detail which lends such beauty to the productions of Riley's pen- 

 cil. Throughout the pages of Mr. Kirby's work we are pleased 

 to find that he has not altogether neglected to consider the eco- 

 nomic importance, or the reverse, of many insects to the agricul- 

 tm-alist, and to vegetation, forests, and plant-life, generally — a 

 department now attracting such universal attention in this coun- 

 try. 



Upon the whole, we may say that this handsomely gotten-up 

 manual presents but little for adverse criticism, when we come to 

 consider wliat tlie volume aims to give, while it offers a great 

 deal to commend it, and it is a work that any entomologist in this 

 country will be proud to see upon the shelves of his library, as it 

 is one that the student of entomology will be constantly called 

 upon to consult. R. W SnaFELDT. 



Primitive Man in Ohio. Vol. I. By Warren K. Moorehead. 

 New York, G. P. Putnam's Sons. 246p. 8vo. Illustrated. 



The problem. Who were the mound builders? has long been 

 one which has interested students of the antiquities of the valley 

 of the Ohio, without much unanimity of conclusion on the part 

 of those who undertook to answer it. Whoever these ancient 

 peoples were, Mr. Moorehead and his collaborators in the work 

 before us have been enabled by a series of admirably conducted 

 investigations to throw a new light on their arts and institutions. 

 These collaborators aie Mr. Gerard Fowke, Dr. H. T. Cresson, and 

 Mr. W. H. Davis; each of whom contributes one or two chapters 

 to the book, on special fields. 



After an opening chapter on palseolithic man, there are descrip- 

 tions of excavations in various sites, the most celebrated of which 

 are Fort Ancient, Madisonville, and Hopewell's Tumuli. The 

 discoveries in the latter were especially rich, and will figure 

 prominently in the archasological department of the Chicago Ex- 

 hibition. They are particularly interesting as in-dicative of an 

 extended use of metals, notably copper. 



An examination of the skulls unearthed shows the contemporary 

 existence of two groups, the one short-headed, the other long- 

 headed; or, are they simply two cranial forms within the same 

 population ? This seems quite as likely. 



The illustiations in the work are faithfully and well executed 

 from the objects, and add both to the beauty and utility of the 

 volume. 



Bffspepsia 



Dr. T. H. Andrews, Jefferson 

 Medical College, Philadelphia, says Oc 



Horsford's Acid Phosphate. 



"A wonderful remedy which gave me 

 most gratifying results in the worst 

 forms of dyspepsia." 



It reaches various forms of 

 Dyspepsia that no other medi- 

 cine seems to' touch, assisting 

 the weakened stomach, and 

 making the process of diges- 

 tion natural and easy.
