TO 



SIR JAMES CLARK, BART. M.D. F.R.S. 



PHYSICIAN IN OKDINABY TO THE QUEEN AND TO PRINCE ALBERT, 

 ETC. ETC. 



MY DEAR SIR JAMES, 



I cannot more appropriately inscribe this Treatise, 

 having for its object the general diffusion of sound Physio- 

 logical knowledge, than to one whose Professional eminence 

 is founded on his enlightened application of it to the pre- 

 vention and cure of Disease, and who has ever been the 

 consistent advocate of Liberal Education. 



The grateful sense I entertain of many acts of personal 

 kindness, makes me feel additional pleasure in paying this 

 humble tribute. 



Believe me to remain, 



MY DEAR SIR JAMES, 

 Your obliged Friend and Servant, 



WILLIAM B. CAKPENTEK. 



UNIVERSITY HALL, LONDON, 

 January } 1859.
