Ap. 27
My dear old George—
I am very very glad of your news about your attacking so difficult a problem with a strong hope of success.2 I confess that I was alarmed when I heard that you cd not get the subject out of your head until I came to your last sentence that you wd be careful.— Do not be too much disappointed if your idea breaks down. It seems a capital idea consulting Adams.3
I am sure some mathematical discussions will be valued greatly by geologists who thought tremendously & it now appears overrated the value of Hopkins work about elevation.—4 There certainly have been enormous changes of level where our continents now stand, & great subsidence in the Pacific. Most geologists now believe that continents have existed nearly where continents now are at all known times— I shall be very glad to help in expence of paid calculation.—5
My dear old f. | Your affect. Father | C. Darwin6
