JDH/1/10 f.63-66, The Royal Botanic Gardens, Kew
Summary:

An account of the geology & vegetation in Indian Plains JDH traversed with Mr Williams' Geological Survey. Area covered was south of the Ganges along the Grand Trunk Road & Soane River encompassing Rotas Ghur & Bidjegur [Bijaigarh] hill forts, the Kymore [Kumaon] & Vindhya hills, Parasnath, Hooghly, Burdwan, Taldangah, Dunwar Pass, Bind Hills, Sultanganje & Calgong, Chunar Rock, table lands of Berbhoom [Birbhum] & Behar, Mirzapur & Bhangulpore [Bhagalpur]. Describes the topography of the landscape & common rocks incl: granite, Hornblende schist, sandstone, quartz, coal nurseries & limestone. He travelled through plains & wooded hills. Comments on extent of mountain ranges in India, one immense range comprising the Rajmahals & Sylhet hills, another the Kymaon [Kumaon] & Vindhya hills, which bounds the Soane & Nerbudda & stretches to the Arabian Sea. The positions of these ranges influence vegetation. The alluvium & kunker which covers everything, the uniform dry climate & flat land exposed to desert winds from Hindustan & solar radiation also determine vegetation. Vegetation lacks variety because of these factors, which override the influences of altitude & latitude; forms are found indicative of altitude in the Nilgherries [Nilgiris] & Ceylon. Flora is less luxuriant beyond the Ganges delta with fewer palms & grasses & more thorny shrubs. The richest areas: Parasnath & upper valleys of the Soane have only a few spp of tree, unadorned with moss or lichen. Bamboo & Ramin replace the Urticae & ferns of moister areas. Timber trees higher up are: Terminalias, Bassia & Diospyros. Lower down are mangos, Tamarind, Figs & Acacias. Soil sterility & aridity limit species of tree: Boswellia, Stercutis, Euphorbiae, & Cochlospermum gossypium will grow in rocky places, some flourish better than others but not depending on rock type. Moister climate nearer Bengal means more luxuriant flora marked by coconuts at Patna & reduction of Acacia arabica at mouth of the Soane.

Summary:

Has heard no more news of his paper; shall he write to the R.S.L. for news? Comments on the claims of James MacCullagh for theories regarding light. Hopes to get something published by the London publishers so has written a paper on trigonometry, which he hopes JH will present to the R.S.L. Doubtless JH is aware that there is no general proof for John Napier's rules.
