Theory of Light Elements (primary rays) three, countervailing qua- 

 lities Transition continuous Equilibrium preserved, all solids, 

 fluids, and gases (save three), are compounds Carbon Diamond 

 Inflammation of the gases Polarity, its diversity Vegetative 

 bodies Crystalline forms assumed by metals, evince their com- 

 pound nature Qualities not innate, depend on polar influence 

 Polarity of Molecules Condensation Relative weight of elements 

 Density equalized Molecules relieved from pressure become 

 isolated and repulsive Separation of constituents produces elec- 

 trical, galvanic, magnetic forces and gravitation its hemi- 

 spherical envelopes their positions electrical currents equili- 

 brium disturbed aurora borealis laminar atmospheric currents 

 restoration of quiescence. Light, identical with caloric, pervades 

 all matter velocity of light undulation, and emanation, how to be 

 reconciled conjunct action produces projection its consequences 7-12 

 Light materiality of sources from whence derived . . .12 



Triangular prism of Newton seven prismatic colours, reduced to four 

 by Wollaston, but three homogeneous coloured rays, according to Sir 

 David Brewster and Mr. Field the intermediates produced by 

 obliquity of conjunction, evident by inequality of tint . . 13 



Field's convex and concave prisms their action on solar light three 

 original coloured rays in annular form refraction of black spot on 

 white ground, of white spot on black ground, by convex lens 

 synthetical composition of light by concave prismatic lens . 14 



Heat a consequence oxydating power of the red ray . .15 



Nature of explosion nitrogen essential to light red ray identical with 

 oxygen, with positive electricity presence of the three elements 

 produce perfect light oxygen and hydrogen produce much heat, 

 and little light why? . . . . .16
