Phenomena 



Developed. 



23. P. 409. — Two homogeneous spheres 

 of the sanie temperature, attract one ano- 

 ther as their ijuantities of matter directly 

 and square of the distance of their centres 

 inversely. 



24. P.410.— Present theory of gravita- 

 tion would not produce the least sensible 

 effect on the system in a period many mil- 

 lion times ?8S7 196067 67 26 10 years. 



25. Ibid. — Activity of present theory of 

 attraction so great, that it would act equally 

 intense on bodies moving either with or 

 against it, with a velocity at least many 

 million million times faster than light. 



26. Ibid. — Resistance of the gravific 

 fluid can produce no sensible effect on the 

 system in a period of many million years. 



27. P. 411. — Attraction is greater the 

 greater the temperature of the attracting 

 body. 



28. P. 412.— EUipticity of the earth by 

 old theory of uniform attraction should be 

 too little by fhe pendulum, and too great 

 by Newton's calculation. 



29. P. 414. — Attraction between par- 

 ticles when they nearly touch increases 

 much faster than the squares of the dis- 

 tances diminish. 



30. Ibid. — Affinity and phsDnomena of 

 chemical action arise from figures of the 

 component particles. 



Con/lrmcd by 



Newton. 



Newton and liaplace tjjat tlie system 

 has apparently the utmost stability, and 

 without foreign interference will continue 

 the same for many thousand years. 



Laplace has proved that the activity of 

 gravitation must be at least six million 

 times greater thari that of light. 



Newton and Laplace show, thai if there 

 be any resistance, it is too small to become 

 sensible in several thousand years.

By pendulum gjg ; by most of the ad- 

 measurements jiy ; and by Newton's cal- 

 culation rjAjj. 



Many chemical phenomena; also by 

 Newton, Desaguliers, Laplace, &c. 



Idea always entertained by our best phi- 

 losophers, but hitherto has not been 

 proved. My late inquiries into the laws 

 of combination between gases with gases, 

 and gases with fluids, &,c. will, I think, 

 demonstrate it. A tolerably fair proof 

 may be drawn from my theory of evapora- 

 tion, vol. ii. p. 363, &c.

31. P. 99 and 100.— Results of two of 

 De Luc's, and one of my own experi- 

 ments. 3Iean difference of the three 

 from my theory ,,',th of a degree Fahr. 

 Mean ditto from old theory, 5-4° Fahr. 

 Ratio of these differences as 1 to 1 62. 



32. P. 98 to 103, and 201 to 211 



Confirmed hy 

 Also by other experiments made by 

 myself on mercury. 



The experiments of Dalton and myself. 



» There has been lately a prize obtained by two French mathematicians for a set of 

 lunar tables completely theoretical ; I do not know what they make the Ann. Equa. ; I 

 have not seen any account of their computations.
