MEMOIR OF CAMPER. 6? 



cularly to the Academy of Drawing established at 

 Amsterdam, were I there to lecture on the subject. 

 The first lectures were delivered in 1770, the sub- 

 sequent ones in 1774 and 1778." 



To this sketch of the method in which these in- 

 vestigations were made, we shall now add the most 

 summary account of the discoveries themselves ; and 

 this we are happy to do in the words of the late emi- 

 nent Dr Cogan, who, attracted to the work by its high 

 celebrity in Holland, and convinced of the truth and 

 great utility of the principles advanced, undertook 

 its translation, and executed it in a manner that has 

 been regarded as a model of such performances. 

 The translation extends to the size of a handsome 

 quarto of 260 pages, divided into two books, and 

 containing nearly a hundred illustrative sketches. 



" The work is based upon the discovery of a more 

 immediate and intimate connexion between the 

 sciences of human and comparative anatomy, and of 

 the natural history of animals, with the art of deli- 

 neation, than could have been supposed to exist. 

 The first books contain the substance of several lec- 

 tures, which was afterwards revised and carefully 

 prepared for publication by Professor Camper him- 

 self. The great object was to shew that natural dif- 

 ferences might be reduced to rules ; of which the 

 direction of the facial line forms the fundamental 

 norma or canon ; and that these directions and inclina- 

 tions are always accompanied by correspondent form, 

 B'ize, and position of the other parts of the cranium,
