 subject, and furnishing indisputable facts.

 of the human mind, he should study it in its connections 

 with the body with which it is so intimately blended. It 

 is in such a study that the lecturer proposed to offer a 

 little help. An intelligent discussion of physiological 

 facts presupposes some knowledge of anatomy. To in- 

 sure a clear understanding of the facts with which we are 

 especially to deal, it is necessary to somewhat particu- 

 larly describe the structure and operations of the nervous 

 system. 



WEDNESDAY, MAKCH 15, 1876. 



THIS evening was given the second of Dr. JOHNSON'S 

 series of lectures. In continuation of the physiological 

 portion of his subject, the lecturer brought forward facts 

 to show that the functions of the brain must largely de- 

 pend upon the character of its blood supply. From 

 these and facts adduced at the previous lecture it appears 

 that some thought does not require us to suppose it to be 

 the activity of a soul using the brain as an instrument. 



He assumed that it was generally conceded, that the 

 mental faculties of animals are not the manifestations of
