ON THE COLOUR &C. OF THE METALLIC OXIDES. 255 



time, the different coloured oxides from the different metals 

 should be selected, which would all bear tbe same degree of 

 heat. — Say 1300 degrees of Fahrenheit's thermometer, conse- 

 quently no two oxides of different colours from the same metal 

 would answer, therefore a knowledge of these principles and 

 their application, would enable the manufacturer to adorn and 

 beautify his wares, and to bring to greater perfection the dif- 

 ferent branches of the arts.

Lancaster, August 1st, 1806, 



DEAR SIR, 



THE following observations, which I request the favour 

 of you to hand to the Philosophical Society, were made at 

 this place on the solar eclipse of the 16th of June last. 



The morning was cloudy till about 9 o'clock, when the sun 

 became visible through thin living clouds: a short time before 

 the beginning of the eclipse, the clouds were so far dissipated, 

 that the limb of the sun was very distinct, and well defined. 

 At 9 h 33' 8" A. M. apparent time, the eclipse began; the 

 first impression made by the moon was at the point expected, 

 and to which my eye was constantly directed. — The end of 

 the eclipse was at O h 18' 56" P. M. apparent time. — A few 

 minutes after the eclipse began, the clouds increased so much 

 as to prevent any measures between the points of the cusps or 

 horns being taken till lo" 44-' 25", when the following series 

 commenced.
