i. (Page 22.) " BRUNO, about the close of 

 the last century, giiessed the fundamental fact 

 of the Nebular Hypothesis, and Kant rea- 

 soned out its foundation idea, and LAPLACE 

 developed it." CORRELATION AND CONSERVA- 

 TION OF FORCES. 



We have learned to recognize on how very 

 doubtful a basis many of the received axioms 

 of physical science are founded. This hy- 

 pothesis has been received with much una- 

 nimity and has firmly held its sway. Yet, 

 " BRUNO guessed the fundamental fact," and 

 this figment of the imagination has, for nearly 

 a century, controlled the scientific mind. Its 

 paralyzing influences have affected other de- 

 partments of physical science, and true prog- 

 ress has been obstructed. The attempt to 

 describe minutely how the spheres were 

 formed millions of years ago is but presump- 

 tion.
