ADDENDUM. An article &quot;Ow the linear motion of heat, Part II.&quot;, written by 

 Sir WM THOMSON under the signature N.N., will be found in the Cambridge 

 Mathematical Journal, Vol. III. pp. 206211, and in Vol. I. of the Author s 

 collected writings. It examines the conditions, subject to which an arbitrary dis 

 tribution of heat in an infinite solid, bounded by a plane, may be supposed to 

 have resulted, by conduction, in course of time, from some previous distribu 

 tion. [A. F.]
