COSMICAL THERMODYNAMICS. 

 By Proi<\ Pliky Earle Chase. 



{Read before the American PhilosopJcical Society, AjJi'il lltJi, 1874.) 



A committee* has been appointed to invite tlie participation of 

 Students in the discussion of a paper 'whicli will be presented at the 

 coming autumn meeting of the Association of German Naturalists and 

 Physicians. Tlie paper is entitled ^^ Losung des Problems ilber Silz und 

 Wesen der Ansiehung,^'^ its object being the identification of gravitating 

 force with thermo-dynamics, by means of the thermal equivalent and 

 Carnot's law of thermo-dynamic energy. 



In compliance with the invitation, and as a conti-ibution to the general 

 theory of unitary force, I submit the following Theses, together with 

 references to portions of my communications to the American Philo- 

 sophical Society during the past eleven years, in which some of them 

 are practically exemplified and verified. 



1. If Force is unitary in its origin, it should be omnipresent in its 

 manifestations. 



3^. In a supposed universal, material, elastic and therefore slightly 

 compressible, luminiferous sether, we may reasonably look for such 

 omnipresent, primitive manifestations. 



3. In a universally undulating aether, any gross inertia of points or 

 particles, must establish special systems of both centripetal and centri- 

 fugal undulations. 



4. The gross, ioert particles, in an asthereal ocean, would be impelled 

 towards each other with velocities varying directly as the sum of their 

 inertias and inversely as the square of their distance. 



5. As soon as a revolution is established around the common centre of 

 gravity of three nearly equal particles, under the influence of asthereal 

 undulations, there should be a tendency to discoid aggregation with a 

 central spheroidal nucleus. 



G. On account of asthereal elasticity, there should also be a subordi- 

 nate tendency to aggregation along lines of logarithmic parabolas or 

 spirals. 



7. In an infinitely diffused nebulous mass, all work would be internal. 



8. In a finite, condensing, nebulous mass, there would be external 

 work, especially manifested in attraction, revolution, and rotation. 



9. As condensation progresses, v' (the velocity of revolution of a fi'ee 



equatorial particle) oc -y/,^. ; v" (the velocity of rotation of a constrained 



i_ 

 equatorial particle) oc ^ oc («')^ ; ff (the velocity of centripetal imiDul-
