[The first three sections of this paper are printed from Nicholson's 

 Journal, Vol. XXXII. (1813), pp. 105125; the remainder from 

 Tilloch's Philosophical Magazine, Vol. XLI. (1813), pp. 439-444, 

 and Vol. XLII. pp. 296-307, and Vol. XLIII. (1814), pp. 64-69. 

 On pages 392, 410, and 412 there are several numerical errors and in- 

 consistencies ; but, as the original French memoirs are not accessible, no 

 attempt has been made to reconcile them.]
