PHRENOLOGY. 



DR. SPURZHEIM'S LECTURES, 



' Know then thyself, presume not God to scan, 

 The proper study of mankind is man.' 



[Agreeable to a promise expressed in our last number, abstracts from 

 the lectures of this distinguished Phrenologist are now presented. A 

 concise view of the principles and foundation of the science having 

 already been given, (No. ix. Vol. 2d) it is deemed unnecessary to repeat 

 them, as laid down by Dr. Spurzheim, except in so far as he had given 

 them a more vivid and interesting character. Many of the valuable re- 

 marks on education and those of a purely philosophical character have 

 been omitted as not strictly adapted to a work devoted to Natural His- 

 tory. . . , . 1 . 1 



From the necessity of frequently clothing the ideas m his own lan- 

 guage, and the impossibility of incorporating the Doctor's manner and 

 expression into the sketch, we are aware that the abstract is inadequate to 

 convey any just idea of the intellectual treat, which a large and most re- 

 spectable audience have so highly enjoyed, to those who have not partici- 



The notes, however, are offered as, in some measure, illustrative of the 

 interesting and important science of Phrenology.]
