heat, in the solid crust into magnetism, in the ocean and air into electricity 

 and light, each new expression of force being but the equivalent of the other, 

 and all in turn contributing to the genesis and continuance of orrjanic -forms 

 which again returning to the earth, yield up their forces to enter into the 

 constitution of senseless shapes through unending cycles. In this inquiry 

 the imperceptible effluences of the solar centre assume visible functions, 

 and an importance in terrestrial changes and in organic creations, which 

 have never heretofore been detected. 



Thus the discovery that all plutonic phenomena spring from the fluctuat- 

 ing play of central forces between the sun and earth, which as molecular 

 aggregates correspond in their mutual relations with known fundamental 

 atomic laws, and which also as cosmical and dynamic functions bear con- 

 stant inverse ratios to the length of the radius vector, connects the first 

 great physical truth discovered by Copernicus, with that sublime conception 

 recently announced by Faraday, respecting the probable identity and con- 

 servation of all force. 



In this sketch all astronomical discussions arc omitted. But that the same 

 facts occur in the sun itself, there can be no doubt, inasmuch as the agitations 

 of its envelops show the same distributions and transitions of the molecular 

 forces, observable on the earth ; and the volcanoes of the moon, and the 

 inequalities of the other planets show a fluctuating play of the same forces to 

 hive taken place within them, acting from their centres outwardly. Neither 

 have the tides of the ocean been here referred to, which on my demonstra- 

 tions prove to be results of reacting or repulsive forces, the contrary 

 of Newton's Theory, inasmuch as the swellings of the sea do not corres- 

 pond with the moon's vertical position as they should if resulting from 

 direct attraction ; but follow a long time after, when the central attractive 

 force has gradually subsided, allowing a reaction of the repulsive force to 

 ensue, as the earth rotates beyond the lunar meridian. As the centralizing 

 force of spheric gravity is excited into greater intensity when under the sun's 

 and moon's meridians, and acts most intensely in radial lines i. e. in 

 great circles tangent to polar circles, through corresponding meridianal as- 

 pects of the earth, it follows that similar effects would be produced in op- 

 posite hemispheres, and that they would be most feeble in that most remote 

 from the sun and moon. And this we observe to be the case in the action 

 of the tides, and in the action of the magnetic force, this last being only an 

 index of molecular motions taking place within the globe in the same man- 

 ner as the tides act without. Besides, Alexis Perry of Dijon, by great 

 labor, has shown singular correspondences between the age of the moon and 

 many earthquakes, a general fact very probably correct, while my theory re- 

 ferring the primal source of all dynamic forces within both planets and satel- 

 lites to the sun, will explain all anomalies, and bring all cosmic phenomena, 

 both near and remote, within the range of more accurate inquiry and more 

 certain solution. 



To make my conclusions more clearly understood, I will sum them up 

 in a few simple propositions ; namely, that an isolated particle of matter at 

 rest, is endowed with two embryonic inactive and insensible essences, which
