PREFACE. 



This work is offered to the public in the hope that it has 

 some desirable features as a text-book, not found in any of the 

 able elementary works on Anatomy and Physiology now ex- 

 tant. One is, the introduction of more of microscopic anat- 

 omy than is usual. Another is, a large addition on Com- 

 parative Anatomy, which is now become a science of great 

 importance. A third is, the Eeligious Applications of these 

 sciences ; which, although all will acknowledge to be emi- 

 nently appropriate, we have found in no elementary treatise. 



We make no pretensions to distinguished attainments or 

 reputation in these sciences, as a reason for writing this book. 

 But both of us have for a great number of years been in the 

 habit of hearing recitations and giving lectures upon them in 

 the College and the Academy, and we ought to know what 

 sort of a text-book is needed. But we dare not boast that we 

 have come up to our ideal. We have tried to give a condensed 

 yet clear exhibition of the leading principles and facts, which 

 are detailed in such works as Carpenter's Human Physiology, 

 his Comparative Physiology, HassaH's Microscopic Anatomy, 

 Griffith and Henfrey's Micrographic Dictionary, Peaslee's 

 Histology, Todd and Bowman's Physiological Anatomy, Wil- 

 son's and Gray's Anatomy, Draper's, Dunglinson's, and Dal- 

 ton's Physiologies, Van Der Hoeven's Zoology, and the works 

 of Cuvier, Owen, Agassiz, Wyman, Leidy, and Wagner on 

 Comparative Anatomy.
