368 MISCELLANEA. [1874. 



meeting, " on which occasion you and your theory of Evolu- 

 tion may be fairly said to have had an ovation." In the same 

 letter Sir Charles speaks of a paper * of Professor Judd's, and 

 it is to this that the following letter refers :] 



C. Darwin to C. Lyell. 



Down, September 23, 1874. 



MY DEAR LYELL, I suppose that you have returned, or 

 will soon return, to London ; f and, I hope, reinvigorated by 

 your outing. In your last letter you spoke of Mr. Judd's pa- 

 per on the Volcanoes of the Hebrides. I have just finished it, 

 and to ease my mind must express my extreme admiration. 



It is years since I have read a purely geological paper 

 which has interested me so greatly. I was all the more in- 

 terested, as in the Cordillera I often speculated on the sources 

 of the deluges of submarine porphyritic lavas, of which they 

 are built ; and, as I have stated, I saw to a certain extent the 

 causes of the obliteration of the points of eruption. I was 

 also not a little pleased to see my volcanic book quoted, for 

 I thought it was completely dead and forgotten. What fine 

 work will Mr. Judd assuredly do ! ... Now I have eased 

 my mind; and so farewell, with both E. D.'s and C. D.'s very 

 kind remembrances to Miss Lyell. 



Yours affectionately, 



CHARLES DARWIN. 



[Sir Charles Lyell's reply to the above letter must have 

 been one of the latest that my father received from his old 

 friend, and it is with this letter that the volumes of his pub- 

 lished correspondence closes.]

 tember.
