sponge : the separation may be compared to the spitting of silver 

 in the act of solidification. 



I was in camp last summer two months with Captain Button 

 on the great lava field of Northern California and Oregon. These 

 immense lava floods are a strong confirmation of your views. 

 These surely have never been erupted by elastic force of vapour, 

 but have been squeezed out. 



The rocks of this coast are puzzling to the last degree. The 

 gradations from unchanged sediments through various degrees of 

 metamorphism to Plutonics is in many places complete and over 

 wide areas. Thanking you again for your pamphlet, and hoping 

 soon to reciprocate, I remain, yours faithfully, 



JOSEPH LE CONTE. 



Although Professor Prestwich was not present in 

 person at the next Annual Meeting of the Geological 

 Society, his thoughts were with his brother geologists. 

 A note addressed to his friend Evans is dated 22nd 

 February 1886. 



I am glad to hear that the Anniversary Meeting went off so 

 well. Your joke was excellent. It would have taken me a week 

 to elaborate a joke on so solemn a subject as the foliation of 



schists. . . . 



It was a trial to him to have been absent. Mr Evans 

 was in the habit of occasionally announcing geological 

 facts to his friend Prestwich in rhyme, especially when 

 the latter was a prisoner to the house from indisposition, 

 and the promotion at this Anniversary Meeting of their 

 common friend Professor Judd, F.R.S., from the post of 

 Secretary to that of President, was told in the following 

 lines : 



" The plant will follow on the seed ; 

 The blossom follows on the bud : 

 The Secretary good at need 

 Blossoms as President in Judd."
