 *' We have arrived safely, after a rough but very short passage of 

 thirteen days from Unalashka. Yery sorry was I \o hear of the 4eath of 

 Dr. Stoliczka. Get for me, if you possibly can, his palseontological volumes 

 of the Indian Survey. Valuable in themselves, they will be especially so 

 to me, as in the last one he adopts my views on the Brachiopods, with some 

 very complimentary remarks .... So busy, I can only add that I go to 

 Washington in a month, to work up the results of our Alaska campaign. 



Address me there, care of the Smithsonian Institute.'
