Temperatures, with Observations on the Conductivity 

 of Hocks, on the Thermal Effects of Saturation and 

 Imbibition, and on a Special Source of Heat in Moun- 

 tain Ranges." Two days later Joseph Prestwich re- 

 ceived telegrams from Paris from two members of the 

 Institute (M. Albert Gaudry being one) to inform him 

 of his election into the Academy of Sciences as a Cor- 

 responding Member in the Section of Mineralogy. Not 

 one of the many honours which he received was more 

 prized, or gave greater pleasure than this. This pleas- 

 ure was shared by his friends, and among the con- 

 gratulatory notes, that from the late Dr W. B. Car- 

 penter, F.R.S., may be cited : 



LONDON, 3rd February 1885. 



MY DEAR PRESTWICH, Pray accept the hearty congratulations 

 of Mrs Carpenter and myself on your election as Corresponding 

 Member of the Institute of France, an honour which you have 

 nobly earned by your long and distinguished services to geo- 

 logical science. It is a great pleasure to me to see so many of 

 my old and valued friends receiving in one way or another 

 that recognition of life-long labours which carries the sense of 

 their value to many who were previously unaware of it. And 

 this becomes the more gratifying when as has been pre- 

 eminently the case with yourself the work has been purely 

 for its own sake, without the least regard to personal interest 

 or public applause. May you long continue to set so good 

 an example to the generation that is now rising into our places. 



I was very sorry to miss seeing you when you were last in 

 town. I had a great many committees and other engagements ; 

 and, hoping to meet you at the Royal Society, I did not take any 

 special step to find you. With kindest regards to Mrs Prest- 

 wich, believe me, always yours faithfully, 



WILLM. B. CARPENTER.
