 transform their dreary "day's darg" into a dis- 

 cipline of nobility thus raising it higher than its 

 own poor merits do above the daily activity of that 

 exemplar of our childhood the busy bee. On the

As we study animal life we see a gradual emer- 

 gence of the fundamental springs of conduct which 

 we find transmuted of course in ourselves. 

 Starting with the simple protoplasts, responsive 

 to oxygen, warmth, food, and one another, and

 the formation of a "body" of which death was 

 the price, the beginning of bilateral symmetry, the 

 consequent acquisition of head brains, the differ- 

 entiation of the sexes. From the stages now per- 

 sistent at different grades of the animal kingdom, 

 we infer that from a primary hunger there arose
