24 GROWTH OF THE 'ORIGIN.' [1844.

 and writing to." I should, five years ago, have thought 

 so. . . . 



[The following letter written on February 23, 1844, shows 

 that the acquaintanceship with Sir J. D. Hooker was then 

 fast ripening into friendship. The letter is chiefly of interest 

 as showing the sort of problems then occupying my father's

 work, when published, which will be quite time enough for 

 my purposes. First for the Galapagos, you will see in my 

 Journal, that the Birds, though peculiar species, have a most

 this object. Talking with Mr. Bentham, he told me that the 

 separate islands of the Sandwich Archipelago possessed 

 distinct representative species of the same genera of Labiatae : 

 would not this be worth your enquiry ? How is it with the
