ERRATUM. 
In Mr. Whewell’s Report on Heat, Electricity, and Magnetism, it is 
stated that a remark of Sir John Herschel’s respecting the temperature 
of the celestial spaces, is contained in a memoir not yet published. 
This is a mistake, the memoir referred to having been published in the 
Qeological Transactions , vol. v. part ii.
