his actions will be characterized. As a text-book for illustrating 

 in a precise method the materials of instruction, this work is 

 especially designed; and the severity and inflexibility of order 

 have not been departed from in treating of a single branch of the 

 subject. 



Among the modern investigations of great interest of which I 

 have availed myself, I may particularly enumerate those of Sir 

 Astley Cooper, Kiernan, Henle, Good sir, and Searle, in addition 

 to the important observations of other excellent anatomists. 



My thanks are especially due to Sir Astley Cooper, who, with 

 his usual urbanity, has furnished me with much useful informa- 

 tion, and has permitted me to emblazon my pages with the flat- 

 tering patronage of his name. I have regarded this condescen- 

 sion of so distinguished a surgeon and physiologist as a sacred 

 trust reposed in my hands, and I have exerted myself to render 

 my labours not unworthy of such gratifying confidence. 



I hope I may be permitted to say that the Engravings are 

 beautiful examples of a most instructive and valuable art. The 

 advantages of such illustrations in a demonstrative science cannot 

 be too highly appreciated. The mode in which the Engravings 

 have been printed, a distinct branch of art in itself, will not 

 pass unnoticed by those who are acquainted with the complicated 

 process and extreme care which are necessary to the production 

 of the delicacy and force of effect of such graphic illustrations. 



In conclusion, it gives me much pleasure to express the obliga- 

 tions which are due from me v to my friend and late pupil Mr. 

 Oliver Thomas Miller, of Her Majesty's Navy, for the patient 

 and industrious perseverance with which he devoted his time and 

 ability during the summer months to assist me in the prosecution 

 of my labours.
