the arcana of Life, and develops the unity and harmony of nature from 

 its very foundation. The object of the Lectures is to demonstrate that 

 a natural method of classifying the animal kingdom, may be attained 

 by a comparison of the changes which are passed through by different 

 animals in the course of their development from the egg to the perfect 

 state ; the change they undergo being considered as a scale to appre- 

 ciate the relative position of the species. — The subject does not admit of 

 condensation into a few pages, and requires numerous figures for its 

 illustration, and we therefore merely announce the work in this our 

 Bibliography. It is a work of vast learning, and profound philosophi- 

 cal research, and should be read and studied by all who are interested 

 in the laws of Life and the history of animals. 



11- Twelve Lectures on Comparative Physiology, delivered before 

 the Lowell Institute in Boston, January and February, 1849 ; by Jef- 

 fries Wyman, M.D. 8vo. Boston : Henry Flanders & Co., 1849. 

 We are indebted for this publication to the accomplished phonographic 

 reporter of Prof. Agassiz's lectures, and their accuracy it is stated, may 

 be equally relied upon. Professor Wyman presents in his series of 

 lectures, a general review of the properties of Living Beings — of Lo- 

 comotion and the Skeleton — Muscular action — Digestion, Absorption, 

 Circulation and Respiration — Nervous system — and the senses, touch, 

 taste, smell, hearing and vision- The author ranges through the ani- 

 mal kingdom in his illustrations, with a facility which could be ac- 

 complished only by a thorough knowledge of natural science in its va- 

 rious departments, and presents his views with clearness and precision. 

 The work is an excellent compend of Comparative Physiology, such a 

 one as the student needs; and the learned reader will value it for 

 many original views and much recent information. 



12. Pioneer History, being a brief account of the first examinations 

 of the Ohio Valley and the early settlement of the Nort/ucest Terri- 

 tory, chief y from original manuscripts, fyc. ; by S. P. Hildreth of 

 Marietta, Ohio. Cincinnati, 1818, pp. 525, 8vo.— Although this work 

 is not devoted to science, its learned and excellent author has done so 

 much for its cause, as is manifest in many volumes of this Journal, that 

 we are not willing to deny ourselves the pleasure of mentioning in our 

 pages this interesting and instructive history of the settlement of a very 

 important part of the United States. 



Sixty years have hardly elapsed since the first permanent settlement 

 was made on the banks of the Ohio below the confluence at Pittsburgh 

 of its two constituent rivers, the Monongahela and AHefhany. Now 

 the state of Ohio alone contains two millions of inhabitants, and is one of 

 the most flourishing and progressive states in the Union ; and six or 

 seven other powerful states lying still to the west have already ex- 

 tended the chain so far, that a link or two more will carry it to the 

 Pacific Ocean. 



Dr. Hildreth was an early pioneer in Ohio— not an actor in the san- 

 guinary conflicts with the aborigines, nor a sufferer in the periods of 

 evere privations of almost every kind, of which starvation -proceed- 

 ,n g to great Buffering if not to actual death— was the chief. He was 

 however early enough on the ground to draw much valuable informa- 

 tion from several of the first adventurers who were still living, and he
