Replies to CD’s questions regarding impregnation of peas, beans, cabbages, and other plants by insects, wind, etc.
Spoke too harshly about CD’s involvement in nomenclatural reform.
JDH used to think CD "too prone to theoretical considerations about species", hence was pleased CD took up a difficult group like barnacles. CD’s theories have progressed but JDH not converted. Sikkim has not cleared up his doubts about CD’s doctrines.
Argument with Falconer.
Charles Darwin [CD] has not been absent from JDH's thoughts during the long break in their correspondence. He probably spoke too strongly about CD's species work & barnacles. speculates that CD was once prone to theoretical considerations about species & unaware of certain difficulties which JDH thought a more intimate acquaintance with species might clear up. Hence was pleased CD took up a difficult group like barnacles. CD's theories have progressed but JDH is not converted. He thought the transitions from one form to another in Sikkim would be more apparent. CD reasons rightly about JDH's Yangma valley; it is undoubtedly a vast moraine. He rejects the Himalayas as an independent chain of mountains & seeks the axis of the great mountain system between the Yarou river & the plains of India. He considers the glaciers of the Himalayan range unrivalled & is convinced they are receding. Explains that it is a double chain likes CD's Andes. [Thomas] Thomson [TT] & [Hugh] Falconer [HF] both regard the greatest Asiatic axis as a sub meridional one. The whole mountain system is incredibly complicated & he exceedingly doubt's Humboldt's system of six Mountain chains. Letter continues under date of 7 Apr. JDH now with HF at Honorable East India Company Botanic Gardens. HF had kept all his letters & overland parcels for five months due to insane procrastination but is now forgiven. HF's society is as ever delightful. HF no longer associates with the Asiatic Society. JDH received CD's Feb letter today & learned that the cold water system has done him much good but is not a cure, JDH sends congratulations on the Darwins' seventh child. JDH came to Calcutta [Kolkata] to persuade Jung Bahadur [JB] to let him travel in Nepal but JB cannot guarantee his safety while absent in England. JDH will therefore go instead to Sylhet then the Khassya [Khasia] Hills & Munnipore [Manipur] with [TT].
"Resolved that the Secretary be requested to ask Mr. Darwin if he would agree to the publication of his work [Living Cirripedia] in parts."
In response to CD’s letter [see 1364] the Secretary is instructed to request that he send a specimen plate to James de Carle Sowerby for estimate of cost.
