Comments on his account.

CD’s vexation at the serious printer’s error in his "Geology" [Collected papers 1: 227–50].

Appreciates what Murray and the printer are doing to rectify the error [transposition of pages of text in "Geology"]. But if the responsible person will be fined heavily, CD would want to "make some present".

Thanks for his obliging note. Has already had one from John Murray. Hopes the Admiralty Manual will bear fruit. Has been at Malvern for three months and his health has improved enormously.

Thanks JFWH for the trouble he has taken to correct printing error in "Geology".

Discusses Dr Gully’s water-cure.

Mentions illness of Emma Darwin.

Comments on CL’s Second visit to the United States [1849].

His water treatment by J. M. Gully.

CD’s contribution ["Geology"] to J. W. Herschel’s Manual of scientific enquiry [(1849), Collected papers 1: 227–50].

Declines to canvass for Richard King.

Water-cure has benefited health.

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]
