VIEWS OF THE MICROSCOPIC WORLD ; designed for General 



Reading, and as a Hand-book for Classes in Natural Sciences. By Prof. Brockles 



by. $1 12. 



By the aid of a powerful microscope, the author has given us highly instructive 

 accounts of Infusorial Animalcules, Fossil Infusoria, Minute Aquatic Animals, 

 Structure of Wood and Herbs, Crystallization, Parts of Insects, &c., &c. 



To those who are necessarily deprived of the aid of a microscope, and even to 

 those who have it, this is a most valuable work. It is clearly and pleasantly written. 

 The sections on the Animalcules, Infusoria, and Crystallization, are very beautifully 

 illustrated with large and expensive plates. The descriptions of the different kinds 

 of these wonderful little animals, many of which multiply by billions in a few hours, 

 are really very instructive. There is no better school library book in the world. It 

 should be read by every man, woman and child. 



HUMAN PHYSIOLOGY ; designed for Colleges and the Higher 



Classes in Schools, and for General Reading. By Worthington Hooker, M. D., 



Professor of the Theory and Practice of Medicine in Yale College. Illustrated with 



nearly 200 engravings. $125. 



This is an original work, and not a compilation. It presents the subject in a new 

 light, and at the same time embraces all that is valuable for its purpose that could be 

 drawn from the most eminent sources. The highest encomiums are received from 

 all quarters ; a few are subjoined. 



From CALEB J. HALLOWELL, Alexandria High School, Va. 



Hooker's Physiology was duly received. We propose to adopt it as a text-book, 

 and shall order in the course of a fortnight. 



From the Boston Medical and Surgical Journal. 



We can truly say that we believe this volume is of great value, and we hope that 

 the rare merits of the diligent author will be both appreciated and patronized. 



From B. F. TEWKSBDRY, Lenoxvtlle, Pa. 



I am ready to pronounce it unqualifiedly the most admirable book or work on the 

 human system that has fallen under my notice, and they have not been few. If any 

 one desires a complete and thorough elucidation of the great science discussed, they 

 can nowhere be better satisfied than in the perusal of Dr. Hooker's most excellent 

 work. 



AN INTRODUCTORY WORK ON HUMAN PHYSIOLOGY, by Prof. 



Hooker, has just been published, designed for all persons commencing the study. 

 Dr. Hooker's works seem to have taken their place decidedly at the head of all 

 treatises on the subject of Physiology. They are rapidly going into seminaries and 

 normal schools in all parts of the country, and the best institutions express their 

 " delight at the result." 60 cents. 



A COMPARATIVE ENGLISH-GERMAN GRAMMAR ; based on the 



affinity of the two languages. By Prof. Elias Peissner, late of the University of 

 Munich, now of Union College, Schenectady. 



From the New York Churchman. 



Of all the German Grammars we have ever examined, this is the most modest and 

 unpretending, and yet it contains a system and a principle which is the life of it, as 

 clear, as practical, as effective for learning grammar as any thing we have ever seen 

 put forth, with so much more pretense of originality and show of philosophy. It 

 will be found, too, we think, that the author has not only presented a new idea of 

 much interest in itself, but has admirably carried it out in the practical lessons and 

 exercises of his work. 



From PROF. J. FOSTER, of Schenectady. 



I have examined Prof. Peissner's German Grammar with some attention , have 

 marked with interest the rapid advancement of students here using it as a text-book, 

 and have myself carefully tested it in the instruction of a daughter eleven years of 

 age. The result is a conviction that it is most admirably adapted to secure easy, 

 pleasant, and real progress, and that from no other work which has come under my 

 notice can so satisfactory a knowledge of the language be obtained in a given time.
