30 FROM NEBULA TO NEBULA 



but are due to current, instantaDeous causes. That the 

 sun's journey through space is gravitational. That the 

 solar system and each and every one of its component 

 systems are "gravitational units" in the sense herein 

 previously denned. That the sun and his systems are 

 not isolated bodies, but integral parts of the great 

 Whole. That the universe is not in the process of "run- 

 ning down," but is self -regulating (as to motion) and 

 self-sustaining. That the so-called centrifugal motion 

 is gravitational. That the empirical law of "conserva- 

 tion of moment of momentum" is a necessary incident 

 of the law of balance as here enunciated. That the 

 earth's continents are huddled about the north pole 

 because of its falling in that direction. That its axis 

 is fixed, compass-like, for the same reason.* That Kep- 

 ler's law is that of the lever. That our month and 

 year are really shortening. That the progressive move- 

 ment of the perihelia of all the planets is due to gravi- 

 tational acceleration. That the sun's apex is nearer the 

 polar star than heretofore supposed. That the ether of 

 space can now have some "body" to it without imperil- 

 ing the safety of the universe. That the planets travel 

 in the same direction, in nearly circular orbits, and in 

 approximately the same plane because these are the 

 shortest cuts to individual and general equipose. That, 

 by necessary implication, comets are violent intruders 

 from other systems and require to be assimilated. 



EOTATIONAL MOTIONS 



If I have succeeded in convincing the attentive 

 reader that current causes are responsible for the 

 motions of revolution around a primary, he will be 

 interested to know whether such causes mav not also 



*The author recognizes the importance of these facts to geology, 

 but reserves their consideration for a future occasion.
