Slough - Richard Jones's book has safely reached him [An Essay on the Distribution of Wealth and on the Sources of Taxation, 1831]: 'It is long since I have met with a work on P.E. [Political Economy] that is intelligible to my obtuse faculties, but this speaks plainly and not in parables. I am afraid it is almost so plain that people won't see how deep it goes'. Thanks for 'the No. of the British containing your views of science and of Lyell' ['Charles Lyell's 'Principles of Geology' volume 1'. British Critic 9, 1831]. JH does not think in many fields of science 'Britain is really the preeminent nation she was - In geology no doubt we take a decided lead, but as to the more other great departments I am not convinced'. JH thinks WW has been too critical of Lyell. Dionysius Lardner has informed JH that WW is to review him ['A Preliminary Discourse on the Study of Natural Philosophy', 1830]. JH recommends WW to read a 'book by Dr. Abercrombie of Edinburgh on the intellectual faculties (or some such title)'. JH gives a short critique of Jones' simplistic expose of Ricardo and Malthus's doctrine of rent.
Cape Town - JH and family have safely arrived at the Cape. Their female servant went mad on the trip and is now in a lunatic asylum. During the voyage JH kept a careful register of the temperature of the water: 'an extremely regular and steady rise from Lat. 20 N. to about the Equator'. He worked the actimometer when he could: 'in the open ocean in typical regions the sun's direct power is usually much greater than in England or the south of France on land at the hottest'. JH hopes to get WW tide results from Mauritius and Madagascar, and will 'make a point of furnishing you data from this place'. During the voyage JH caught quantities of luminous animals. Cape Town is an 'Earthly Paradise'. JH hopes to have his 20-foot reflecting telescope erected within a month. WW to tell [Charles] Lyell that JH 'read with the highest delight his 3rd Vol.' [Principles of Geology, Vol. 3, 1833].
JGL encloses 'a cheque for Mr Murray in acknowledgement of your friend's share in the art on yr second volume'. JGL is not impressed with it.
