At Madras [Chennai] JDH asked about cheetahs. Conveys observations on their domestication & hunting. Describes hawking practices & birds used. Observes that natural features separate species but this is only one factor, e.g. different antelopes found on either side of River Soane which should not be a barrier to migration. The different types of Indian elephant also an example of races in districts. Discusses kinds of wild & domesticated dogs & cattle. The native Bison is extinct. Sciurus maximus: Peninsular Squirrel, is example of locality-specific colouring. From behaviour of alpine & plain species observes animals are more able to adapt to heat than cold, altitude a factor. JDH wants a specimen of an alligator from Zillah Shahabad. Deforestation changing climate & killing crocodiles. Observes Sand Martins nests colonised by Phalangium spiders & comments on diurnal migration of Neilgherry Ghaats [Nilgiri Ghats] swallows. Plains are alluvial deposits with interesting mineralogy. Will send Forbes a letter re. coal formation. Re. botany, as Darwin is interested in vegetation of isolated mountains, JDH comments on flora of one he climbed incl. barberry. Has found new species of Vallisneria. 4 Mar: JDH left Williams' geological survey to go to Mirzapore, Calcutta [Kolkata] & Darjeeling in Sikkim Himalaya. JDH's address is botanic garden Calcutta, care of Falconer. Recounts passage out to India. Has stayed with Sir L. Peel, Mr Colvile nephew of Lord Auckland, & at Government House.

Thomson is in Yarkand studying geology & botanical geography, Cunningham in Cashmere [Kashmir] & Strachey in Chinese Tibet. Mentions Equus hermionus, an Auroch horn, his health & plan to go to Cherra Poonjee in Sylhet. Mar 8: en route to Bhagulpore down Ganges.
