ftrength of the faculties by the development of the relative 

 organs. 



In the lad place, the 4th principle, the moft important 

 for praftice in regard to the fyikm of Dr. Gail, is : 



IfVe may judge of thefe different organs and of their facul- 

 ties by the exterior form of the cranium. 



The truth of this principle is founded upon another, viz. 

 thit the conformation of the cranium depends on that of the 

 brain ; a truth generally acknowledged, and proved by the 

 anterior ffert of the brain, by the impreffions in the anterior 

 part of the cranium, and by other fafts. 



[There arcfkullir,it istrue,in whichan external protuberance 

 of the bone correfponds to an interior one; and this irregu- 

 larity, which is found fometimcs as a difeafe, and moft com- 

 monly at an advanced age, when the cerebral organs do not 

 oppofe the fame refiftance to the cranium, renders the prac- 

 tice of Dr. Gall's fyftem, in fome meafure, uncertain.] 



Guided by thefe principles. Dr. Gall examines the nature 

 of the (kull, compares the crania of animals and thofe of men 

 analogous and diflcrent in faculties. His refearches have 

 proved to him, in a manner almoft inconteftable, not only 

 the above truths, but that the faculties of animals are ana- 

 logous to thofe of man; that what we call inftinft in ani- 

 mals is foimd alfo in the latter, fuch as attachment, cunning, 

 circumfpeftion, courage, &c.; that the quantity of the or- 

 gans fixes the difference of the genus ot animals, their re- 

 ciprocal proportion that of individuals; that the difpofition 

 oris:inally eiven to each faculty by nature may be called forih 

 by exercife and favourable circumflances, and fometimes by 

 difeafe, but that it never can be created in the cafe where it 

 has not been given by nature*; that the accumulation of 

 the organs takes place in a conftant manner from the hind 

 part forwards, from the bottom to the top, in fuch a manner, 

 that animals in proportion as they approach man in the quan- 

 tity of their faculties have the fuperior and anterior part of the 

 brain more expanded ; and, in the laft place, that in the moft 

 perfe<it animal, man, there are organs in the anterior and 

 fuperior parts of the frontal bone, and of the parietals, deftined 

 for faculties which belong to them exclufively. *' It is under 

 the latter point of view^ that the difcoveries of Dr. Gall agree 

 perfeAlv with the tlieory of the facial angle, which feems 

 Hill further to eftablifh the truth of them."
