Pleasure at receiving CD’s scientific letters to JDH and Hodgson.
The H. Wedgwoods’ pecuniary loss.
Condolences at CD’s father’s death.
Rajah harasses JDH’s work. Lack of supplies, rain, malarial valleys, and landslips make going difficult. Cannot get into Tibet.
"Twenty species [of plants] here [Camp Sikkim] to one there [Tierra del Fuego?] always are asking me the vexed question, ""where do we come from?""."
From observation of terraces descending to steppes and plains of India, he thinks that the Himalayas were once a grand fiord coast.
Has information CD requested on Yangsma valley. JDH’s detailed hypothesis of origin of dam there. Does not agree with CD’s interpretation.
JDH writes to [Charles] Darwin [CD], having read his letter & the one to Hodgson with interest. He expresses his sympathy for CD’s bereavement & H. Wedgewood’s pecuniary loss. JDH discusses CD’s health. The Rajah is being difficult but JDH refers all his grievances to [Archibald] Campbell at Darjeeling. He has reached the Tibetan borders north east of Darjeeling but his Lepchas are afraid. JDH discusses food & provisions; he is clear of the 'malarious' valleys. He wishes to compare the cis & trans slopes but cannot go into Tibet. He compares the landscape to Salvator Rosa’s paintings. The vegetation is rhododendron scrub with pines below. JDH describes exploring the Terai plains & discusses the geology & history of the Himalayas. JDH discusses the particulars & possible glacial formation of the Yangma Valley lake beds & terraces & includes small sketches. He refers to CD’s remarks on the granite construct of the Cordillera [Letter appears incomplete]
Discusses CL’s Second visit to the United States [1849]. Corrects CL’s error regarding location of Megatherium finds.
Continues water-cure treatment at home and must do so for a year. Considers himself absolutely cured.
Returns the enclosed from his brother [Erasmus Alvey Darwin]
Accepts EHS’s invitation for Thursday.
Describes his research on cirripedes: an "anatomical and systematic catalogue". Asks to borrow specimens.
Thanks MATW for the results of her experiments on the inheritance of caterpillar peculiarities and would be grateful for any further observations on differences in structure or habits between silkworm breeds, or peculiarities in inheritance.
Thanks J. D. Dana for cirripede specimens. Describes his work. Comments on Ibla. Would like to see AAG’s notes and figures on Anatifa. Asks for references to cirripede descriptions by T. A. Conrad.
Regrets that state of his health prevents acceptance of invitation [to be present at inauguration of J. S. Henslow as President of Ipswich Museum in Dec 1850].
Discusses effect of subsidence and elevation on deposits. Cites examples along coasts of South America and Wales. Proposes theory to explain thickness of deposits in south Wales.
Asks CL’s opinion of his theory of "craters of elevation" described in Volcanic islands.
Mentions CL’s comparison of Mississippi beds to the Pampas.
Comments on Poulett Scrope’s views on the separation of basalt and trachyte.
Describes his cirripede work.
Describes his research on cirripedes.
Comments on paper by AH ["Notice of a burrowing barnacle", Ann. & Mag. Nat. Hist. 2d ser. 4 (1849): 305–14]. Asks to borrow specimens.
Asks to borrow cirripede specimens. Describes his research.
Describes the Birmingham meeting [1849] of BAAS.
His health is poor. Continues with water-cure with considerable benefit.
Thanks AH for specimens of Alcippe.
Discusses capacity of Lithotrya to bore its own hole. Believes Arthrobalanus also makes cavities this way.
Asks to see paper on cirripedes by Sven Lovén.
Comments on paper by AH [see 1253].
CD partly right. JDH was calling "stratification" what CD calls "foliation". Answers CD’s question on cleavage foliation in Himalayas. Glacial action.
Charmed by CD’s Admiralty instructions on geology [in Manual of scientific enquiry (1849), Collected papers 1: 227–50], but complains he does not give prices of books and instruments he recommends.
No summary available.
Discusses cirripede specimens borrowed from HC.
Thanks JSH for information and suggestions on benefit clubs,
and for a shipment of fossil cirripedes.
