however find, that it is agreeable to the tenets of other philosophers, 
and of such authority that only what is truly Nature can prevail." 
With regard to Mons. Rochon's experiments on the fixed stars, 
it will be found by the chromatometer, &c., that a proportional 
smallness and distance may readily be calculated; and it is depen- 
dent on these, whether they have white in the centre like the figure 
of the sun, or are like the star Sirius as it were composed of the 
three colours, viz., red, green, and violet, with a feeble shade of 
yellow or not, exactly like Dr. Wollaston's small ray of light, so that 
its measure when observed by Mons. Rochon was equal, or nearly 
so, to the diameter of that ray in the star Sirius, and that were he 
nearer the star, or the star larger, the tints would be proportionally 
different. Thus Sirius is comparatively as a thread or narrow ray 
of light, the planets are in their proportions and distances broader, 
and the sun broadest, (to our Earth) from whose glorious light are 
derived the three perfect primitive prismatic colours, naturally the 
parents of all others by mixing and forming binaries, and ternaries, 
in due order, till lost in night or darkness, when with a new re- 
turning morn it again renovates the system. 
I need say nothing on the ingenious Dr, Herschel's paper in the 
Philosophical Transactions, as he knows how to appreciate truth 
while he is searching for her, and is so nearly on the brink of dis- 
covery.
