ON THE EDUCATIONAL VALUE OF THE 

 NATURAL HISTORY SCIENCES. 



THE subject to which I have to beg your attention 

 during the ensuing hour is " The Kelation of Physio- 

 logical Science to other branches of Knowledge." 



Had circumstances permitted of the delivery, in 

 their strict logical order, of that series of discourses 

 of which the present lecture is a member, I should 

 have preceded my friend and colleague Mr. Henfrey, 

 who addressed you on Monday last ; but while, for 

 the sake of that order, I must beg you to suppose that 

 this discussion of the Educational bearings of Biology 

 in general does precede that of Special Zoology and 

 Botany, I am rejoiced to be able to take advantage of 

 the light thus already thrown upon the tendency and 

 methods of Physiological Science. 



Eegarding Physiological Science, then, in its widest 

 sense as the equivalent of Biology the Science of 

 Individual Life we have to consider in succession : 



1. Its position and scope as a branch of knowledge. 



2. Its value as a means of mental discipline. 



3. Its worth as practical information. 

 And lastly, 



4. At what period it may best be made a branch of 

 Education.
