CARPENTER'S COMPARATIVE PHYSIOLOGY. 



BLANCHARD & LEA, 



PHILADELPHIA, 



HAVE JUST ISSUED 



PRINCIPLES OF PHYSIOLOGY, 



GENERAL AND COMPARATIVE. 

 BY WILLIAM B. CAKPENTER, M.D., F.R.S., ETC. 



THIRD EDITION, GREATLY ENLARGED. 



IN ONE VERY HANDSOME OCTAVO VOLUME, OP OVER 1100 PAGES, WITH 321 BEAUTIFUL WOOD-CUTS. 



This great work will supply a want long felt by the scientific public of 

 the country, who have had no accessible treatise to refer to, presenting, in an 

 intelligible form, a complete and thorough outline of this important subject. 

 The high reputation of the author, on both sides of the Atlantic, is a sufficient 

 guarantee for the completeness and accuracy of any work to which his name 

 is prefixed; but this volume comes with the additional recommendation that it 

 is the one on which the author has bestowed the greatest care, and on which 

 he is desirous to rest his reputation. Two years have been devoted to the pre- 

 paration of this edition, which has been thoroughly remoulded and rewritten, 

 so as, in fact, to constitute a new work. The amount of alterations and addi- 

 tions may be understood from the fact that of the ten hundred and eighty pages 

 of the text, but one hundred and fifty belong to the previous edition. Con- 

 taining, as it does, the results of years devoted to study and observation, it 

 may bo regarded as a complete exposition of the most advanced state of 

 knowledge in this rapidly -progressive branch of science, and as a storehouse 

 of facts and principles in all departments of Physiology, such as perhaps no 

 man but its author could have accumulated and classified. 



In every point of mechanical execution, and profuseness and beauty of illus- 

 tration, the Publishers risk nothing in saying that it will be found all that the 

 most fastidious taste could desire. 



" A truly magnificent work. In itself a perfect physiological study." Banking's Abstract, July 21, 1851. 



" It is impracticable for us to give an analysis of the varied contents of this most useful volume. Its pro- 

 duction has been a labour of love with its author, and has subjected him to much thought, and to no litt u 

 toil, without the expectation of pecuniary profit. It is to be hoped, however, that so much ability, zeal, 

 and industry, may meet with their reward, and that future editions may remunerate him for productive 

 exertions so beneficial in their results to others. We may remark, in conclusion, that the work is beautifully 

 gotten up in the English fashion, and that the illustrations are in the first style of art." Medical Examiner. 



" This work stands without its fellow. It is one few men in Europe could have undertaken; it is one no 

 man, we believe, could have brought to so successful an issue as Dr. Carpenter. It required for its produc- 

 tion a physiologist at once deeply read in the labours of others, capable of taking a general, critical, and 

 unprejudiced view of those labours, and of combining the varied, heterogeneous materials at his disposal, so 

 us to form an harmonious whole. 



" We feel that this abstract can give the reader but a very imperfect idea of the fulness of this work, and 

 no idea of its unity, of the admirable manner in which material has been brought, from the most various 

 sources, to conduce to its completeness, of the lucidity of the reasoning it contains, or of the clearness of 

 language in which the whole is clothed. Not the profession only, but the scientific world at large, must 

 feel deeply indebted to Dr. Carpenter for this great work. It must, indeed, add largely even to his high 

 reputation." Medical Times. 



" This is a book without a rival; and Dr. Carpenter has laid the medical profession, as well as all who 

 study and who love natural history, under deep and lasting obligations by its production. Our limits 

 forbid us from indulging in comment or criticism; and we can only heartily commend the work to our 

 readers." London Journal of Medicine. 



"The present edition contains upwards of one thousand pages, in close type, and includes a mass of infor- 

 mation not to be easily found, even in a well-furnished library. Physiology, Zoology, Botany, and Micro- 

 scopy, all lend their aid to the elucidation of the laws of life and development; and the style is such as to 

 interest the reader, and to fix his attention upon the particular subject to which he has occasion to refer. 

 We must also observe that the beautiful and accurate illustrations which accompany this edition (exceed- 

 ing three hundred in number) make plain to the eye that in which description would fail, and materially 

 a,id the author in familiarizing his readers with the results of numerous microscopical observations. 



" It is our opinion that whether for reference or study in the subject to which it specially refers, no better 

 book than Dr. Carpenter's 'Principles of Physiology, General and Comparative,' can be placed in the hands 

 of student or practitioner. It would also be a valuable addition to the library of every well educated man, 

 although not a member of the profession." London Medical Gazette. 



" I recommend to your perusal a work recently published by Dr. Carpenter. It has this advantage, it is 

 very much up to the present state of knowledge on the subject. It is written in a clear style, and is well 

 illustrated." Professor S.'tar/ ey's Introductory Lecture. 



"In Dr. Carpenter's work will be found the best exposition we possess of all that is furnished by compa- 

 rative anatomy to our knowledge of the nervous system, as well as to the more general principles of life and 

 organization." Dr. JfcUand's Medical Notes and Reflections. 



"See Dr. Carpenter's ' Principles of General and Comparative Physiology,' a work which makes me proud 

 to think he was once my pupil." Dr. Elliotson's Physiology.
