 faith in witches, ghosts, transmutations, and 

 transmigrations. 



There are some who think little of scientific 

 truth, but, comparatively speaking, care much 

 to recognise the Almighty Will as the primary 

 cause of all things. 



Such persons will find that this power and 

 will are shown in the inseparable union of 

 ponderable matter and force quite as much as 

 if he had willed to make them completely 

 separable. 



We, who search for truth above all things, 

 are compelled by our belief in the insepara- 

 bility of matter and force in the abiological 

 sciences to work out the inquiry how far this 

 inseparability holds true in the biological 

 sciences also. 



Our ideas of the grandeur, the unity, and the 

 power of the first cause will surely not be 

 lessened if it can be shown that one law of the 

 union of force and matter and of the conserva- 

 tion of energy obtains throughout the organic 

 as well as throughout the inorganic creation.
