THE following work is intended to furnish the Student and 

 Practitioner in Medicine and Surgery with a plain and accurate 

 view of the intimate structure and functions of the human body, 

 and is accommodated, in its plan and arrangement, to the phy- 

 siological lectures delivered in King's College, London. The 

 authors have had a joint share in its composition, and are 

 equally responsible for all it contains. 



Incorporated in various parts of the work, the reader will find 

 opinions expressed, relating both to the structure and functions 

 of parts, more or less at variance with those generally received. 

 To these the authors for the most part have been led during 

 their anxious attempts to render their descriptions direct and 

 faithful transcripts from nature. 



Historical details, conflicting statements, and intricate discus- 

 sions of doubtful physiological questions, have been almost wholly 

 avoided, as being inconsistent with the end in view. 



The authors desire to acknowledge their obligations to Mr. 

 Vasey, the able and intelligent artist, by whom the engravings 

 have been executed on wood. 



They have likewise to express their regret at the delay which 

 has occurred in the progress of their work. When the First 

 Part was published in February, 1843, it was thought that the 

 remainder might appear in two more Parts in the course of 

 the following year. As their labours proceeded, however, it 

 became necessary in some measure to modify the original plan, 

 and to produce the work in two Volumes, of which the First is 

 now complete. The remaining Volume will follow, in two Parts, 

 at an early period. 



KING'S COLLEGE, LONDON, 

 April, 1845.
