the demands of both, and tlu*ongh the aid of an unusually large numt)er of 

 excellent woodcuts, it affords the greateftt ])ossible aid in the definition and 

 means of identifying the speeimens in hand. Tliat a work which should be 

 useful to farmers ami gardeners should treat especially of the useful and 

 injurious insects is evident. This part of entomology has within the last 

 ten years made great progress. Packard has here also understood how to 

 preserve a right proJDortion in the choice and handling of his material. 

 * * We may consider Packard's work as among the best guides 

 to the study of insects which at present exist. We close our notice with 

 the hope tlvat the book may find its way in Europe as rapidly as it seems 

 fo have in America. — Translation from the jEntomological Journal of 

 BtMin, Prussia. 



It fill s a gap in American entomological literature, is well written and 

 amply illnstrateil, and we hope will meet with the success it deserves; 

 The work will be found an int^aluahle guide to the study of insects. — The

Dr. Packard's Gutde is a work which we ti-ust will find its way to all 

 ■who take any interest, scientific or pi-actical, or both, in the world of in- 

 sects. It is designed to assist the student in learning the structure, trans- 

 formations and development of in.^ects. to direct bimin their collection and 

 preservation, and to help him in the identification of his captures. It is 

 also intended to aflord a useful account of those classes of insects that ai'e 

 especially injurious to vegetation, and at the saxae time draw attention, to 

 those that are beneficial. — Canada Parmer. 



The study of Entomology is one that can be almost as eaeily pursued in 

 the school-room as Botany, and we should be glad to see the experiment 

 tried. Dr. Packai-d's work is well fitted, by its clear, simple style, for use 

 as a text-book. — The Michigan Teacher. • 



The insects injurious and Jjeneflcial to vegetation are especially noticed. 

 In typography and illustrations it leaves nothing to be destred, wliile the 

 author's style is veiy perspicuous. We hope tiie work will be used as in- 

 tended in colleges and farm-schools, and by agriculturists.— T/je Nation. 



Altogether, we are immervsely pleased with this work. It is assuredly all 

 in all the fullest, most modern, and most clearly-written ti-eatise on insects 

 we have ever seen, and we heartily commend it to our readers' notice, 

 feeling cei-t;un their judgmejit of its merits will not be less favorable than 

 our own. — Pojmlar Science Revieio, Liondon. 



The first portion of this book, occupying nearly two parts, is devoted to 

 general entomology, and furnishes an "aduih-able, though necessarily brief, 

 account of their organization, of their reproduction and development in 

 the egg and of their metamorphoses. The most recent memoirs, connected 

 with these subjects, have been made use of by the author, and this part of 

 bis work is certainly the best manual of entomology which the Engliali 

 reader can at present ohtam,— Nature, London. 



As a practical treatise on Airrerican Entomology, witli reference espec- 

 ially to the insects injurious or beneficial to crops, it etamls almost alone,

The "American Naturalist" is an elegantly printed and ably conducted 

 magazine, which we have already had occasion to notice as from the pi-ess 

 of the Peabody Academy, of Salem. One of its editors is the author of 

 this GtiTDB TO THE STUmT OP INSECTS, and the elegant tyiwgraphy and 

 illnsti-ations. so chiiracteristic of that magazine, and the zeal and schokir- 

 ship of Mr. Packard, makes this by far tlie best work in tlie language on 

 this subject. The stndv of insects is becoming the most popular brancli of 

 naturdl history. — New York Independent. 



It is a treatise which any intelligent farmer may study with pleasure and 

 profit, and one which will at the same time greatly edUy even the learned 

 naturalist. — New York Observer.
