340 JAMES CLERK MAXWELL. [CHAP. XI. 



Him in the flesh we should not have known Him any better, 

 perhaps not so well. Pray to Him for a constant sight of 

 Him, for He is man that we may be able to look to Him, 

 and God, so that He can create us anew in His own 

 image. 



To C. HOCKIN, Esq. 



Glenlair, Dalbeattie, September 7th 1864. 



... I have been doing several electrical problems. I 

 have got a theory of " electric absorption," i.e. residual 

 charge, etc., and I very much want determinations of the 

 specific induction, electric resistance, and absorption of good 

 dielectrics, such as glass, shell-lac, gutta-percha, ebonite, 

 sulphur, etc. 



I have also cleared the electromagnetic theory of light 

 from all unwarrantable assumption, so that we may safely 

 determine the velocity of light by measuring the attraction 

 between bodies kept at a given difference of potential, the 

 value of which is known in electromagnetic measure. 



I hope there will be resistance coils at the British 

 Association. 



To PROFESSOR LEWIS CAMPBELL. 1 



8 Palace Gardens Terrace, 

 London, TF., 22d November 1864. 



It was very kind of you to think of me at this time, and 

 write to me. I shall always remember your mother's kind- 

 ness to me, beginning more than twenty-three years ago, and 

 how she made me the same as you two when I came to see 

 you. To you her memory is what you can share with none, 

 so I can say no more except that you will continue to find 

 that to have had a mother so devoted to her duty gives you 

 a consciousness of your own obligations which will be 

 strengthened whenever you think of her. 



1 Mrs. Morrieson died on the 17th of November 1864.
