 sizes and constructions, illustrated by select 

 observations. Phil. Trans. 1800, pp. 49-85.

4. Experiments on the Solar and on the Ter- 

 restrial Rays that occasion heat, with a compara- 

 tive view of the laws to which Light and Heat, 

 or rather the Rays which occasion them, are

5. Observations tending to investigate the 

 nature of the Sun, in order to find the causes or 

 symptoms of its variable emission of Light and 

 Heat ; with remarks on the use that may pos- 

 sibly be drawn from solar observations. Phil. 

 Trans. 1801, pp. 265-318. 



6. Additional observations tending to in- 



vestigate the symptoms of the variable emission 

 of the Light and Heat of the Sun ; with trials

 the solar rays through liquids ; and a few re- 

 marks to remove objections that might be made 

 against some of the arguments contained in the 

 former paper. Phil. Trans. 1801, pp. 354-

 spurious diameters of celestial and terrestrial 

 objects ; with an application of the result of 

 those experiments to a series of observations on 

 the nature and magnitude of Mr. HARDING'S
