BIBLIOGRAPHY OF IIERSCIIEL's WRITINGS. 518 



On the power of penetniting into space by telescopes, with a comparative deterinina- 

 tion of the extent of that power in natural vision, and in telescopes of various 

 sizes and constructions, illustrated by select observations.

 Investigation of the powers of the prismatic colors to heat and illuminate objects, 

 with remarks that prove the diU'erent refrangibility of radiant heat. To which 

 is added an inquiry into the method of vii'wing the sun advantageously Avith 

 telescopes of large apertures .and high magnifying powers.

 Experiments on the solar and on the terrestrial rays that occasion heat, with a com- 

 liarative view of the laws by which light and heat, or rather the rays that occasion 

 them, arc subject, in order to determine whether they are the same or different.

 Observations tending to investigate the nature of the sun, in order to find the causes 

 or symptoms of tts variable emission of light and heat, with remarks on the use 

 that may iiossildy be drawn from solar observations.

Additional observations tending to investigate the symptoms of the variable emission 

 of the light anil heat of the sun, with trials to set aside darkening glasses by trans- 

 mitting the solar raj'S through liquids, and a few remarks to remove objections 

 that might be made against some of the arguments contained in the former pap6r.

 angles, and to distinguish the real from the spurious diameters of celestial and 

 terrestrial objects, with an application of the results of those experiments to a
