Experiments on the solar and on the terrestrial rays that occasion heat, with a comparative view of the laws by which light and heat, or rather the rays that occasion them, are subject, in order to determine whether they are the same or different. _Phil. Trans._, 1800, pp. 293-326, 437-538. _Gilbert Annal._, X. (1802), pp. 68-78; _same_, XII. (1803), pp. 521-546.
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 possibly be drawn from solar observations. _Phil. Trans._, 1801, pp. 265-318. _Bode's Jahrbuch_, 1805, p. 218, and 1806, p. 113.

Additional observations tending to investigate the symptoms of the variable emission of the light and heat of the sun, with trials to set aside darkening glasses by transmitting the solar rays through liquids, and a few remarks to remove objections that might be made against some of the arguments contained in the former paper. _Phil. Trans._, 1801, pp. 354-362.
