Vlll PREFACE. 



of Blumenbach, and that much of the original would require 

 emendation on account of recent discoveries or might be 

 better omitted, and that the disjointed nature of the work 

 would be a source of greater inconvenience to the reader 

 than ever, I resolved to remodel the whole, omitting many 

 parts of the original, and blending my notes with as much of 

 it as I could retain : and as the portions of the original 

 retained are of so much smaller amount than my own labours, 

 and of a very elementary character, and the proportions of 

 Blumenbach's share and my own thus completely reversed, I 

 feel satisfied that, in now giving my own name to the work, 

 I shall be justified in the eyes of even the celebrated and 

 venerable Blumenbach, who, though eighty-three years of age, 

 still delivers his lectures at eight o'clock every morning. The 

 passages with inverted commas and no farther intimation are 

 from Blumenbach. I have illustrated many pages with wood- 

 cuts, from Dr. Jules Cloquet's collection, for the sake of the 

 general reader ; since works of this description are now read 

 as much out of the profession as by medical men. 



The correction of any errors, and the communication of 

 any facts, either publicly or privately, will always be esteemed 

 by me a valuable favour.
