helps them from near by, is called upon for duties which to the 

 inexperienced appear simple and easily performed, but are in- 

 deed of a perplexing and exhausting nature. All sympathetic 

 action is taxing to the strength of men. When we go forth to 

 another, making his life our own, we attain our end by ways of 

 exceeding difficulty, by paths which are not beaten, which can

 to take away so much from my share of vitality as the struggle 

 to gain a hold on the mind of some youth who, by nature re- 

 mote from human ways, must be firmly grasped before he can 

 be helped."

 " Importance of Understanding the Relation of Earth to Man, 1 ' 

 " Importance of the Sense of Beauty." Others read as follows :

 study of the growth of a science. Dependence of the growth of a science upon 

 the way the phenomena are exhibited. Dependence upon the mental char- 

 acters of the races. Close likeness of the Greek scientific spirit to our own, 

 utter diversity of Hebrew. Supernatural spirit opposed essentially to the
