358 LIFE AT DOWN. ^TAT. 33-45. [1854. 



Cordillera being often struck with the greater abruptness cf 

 the strata in the low extreme outermost ranges, compared 

 with the great mass of inner mountains. I dare say you will 

 have thought of measuring exactly the width of any dikes 

 at the top and bottom of any great cliff (which was done by 

 Mr. Searle [?] at St. Helena), for it has often struck me as 

 very odd that the cracks did not die out oftener upwards. I 

 can think of hardly any news to tell you, as I have seen no 

 one since being in London, when I was delighted to see 

 Forbes looking so well, quite big and burly. I saw at the 

 Museum some of the surprisingly rich gold ore from North 

 Wales. Ramsay also told me that he has lately turned a

 with the Labyrinthodon. No doubt you see newspapers, and 

 know that E. de Beaumont is perpetual Secretary, and will, 

 I suppose, be more powerful than ever ; and Le Verrier has

 theory, viz. that the whole red clay and flints over the chalk 

 plateau hereabouts is the residuum from the slow dissolution 

 of the chalk ! 



As regards ourselves, we have no news, and are all well. 

 The Hookers, sometime ago, stayed a fortnight with us, and, 

 to our extreme delight, Henslow came down, and was most 

 quiet and comfortable here. It does one good to see so com- 

 posed, benevolent, and intellectual a countenance. There 

 have been great fears that his heart is affected ; but, I hope 

 to God, without foundation. Hooker's book * is out, and 

 most beautifully got up. He has honoured me beyond meas- 

 ure by dedicating it to me ! As for myself, I am got to the 

 page 112 of the Barnacles, and that is the sum total of my 

 history. By-the-way, as you care so much about North 

 America, I may mention that I had a long letter from a ship- 

 mate in Australia, who says the Colony is getting decidedly
