6 PREFACE. 



Biology to the contemplation of the vast temple 

 of animated nature, with its varied compartments 

 intimately connected with each other, and with 

 the central one of all, the human type. In every 

 avenue and chamber and dome of this wondrous 

 edifice the Christian student recognizes the truth 



that " POWER BELONGETH UNTO GOD." 

 OAKLAND, CAL., January, 1880.
