198 THE SCIENTIFIC RESULTS OF V 



from those who are reaping golden harvests through 

 the science of a past generation. 



When we remember that science is really no more 

 nor less than such accurate and full knowledge of this 

 or that class of natural things as enables us actually

As a matter of fact there is no such antithesis. 

 Your man of science is, or should be from the nature
