Errata

Errata in the former Paper, Phil. Trans. 1830. The following errata in my former paper have arisen from my having omitted to add the initial $32^\circ$ in the reduction of the Centigrade scale to that of Fahrenheit. Page 266, line 24, for $360^\circ$, read $392^\circ$. — 266, — 26, — 360°, — 392°. — 266, — 27, — 360°, — 392°. — 269, — 3, — 360°, — 392°. — 269, — 5, — 360°, — 392°. — 269, — 23, — 360°, — 392°. — 269, — 25, — 360°, — 392°.
