VI.—Yet notwithstanding what Mill says, it is clear that Malthus himself lays great stress upon his geometrical and arithmetical ratios, and it is also probable that it is to these ratios that Malthus is largely indebted for his fame, as they supplied one of those high-sounding formulas that with many people carry far more weight than the clearest reasoning.
[15] The effect of the Malthusian doctrine upon the definitions of capital may, I think, be seen by comparing (see pp. 32, 33, 34) the definition of Smith, who wrote prior to Malthus, with the definitions of Ricardo, McCulloch and Mill, who wrote subsequently.

[19] Malthus’ other works, though written after he became famous, made no mark, and are treated with contempt even by those who find in the Essay a great discovery. The Encyclopædia Britannica, for instance, though fully accepting the Malthusian theory, says of Malthus’ Political Economy: “It is very ill arranged, and is in no respect either a practical or a scientific exposition of the subject. It is in great part occupied with an examination of parts of Mr. Ricardo’s peculiar doctrines, and with an inquiry into the nature and causes of value. Nothing, however, can be more unsatisfactory than these discussions. In truth Mr. Malthus never had any clear or accurate perception of Mr. Ricardo’s theories, or of the principles which determine the value in exchange of different articles.”
[20] I say considerable country, because there may be small islands, such as Pitcairn’s Island, cut off from communication with the rest of the world and consequently from the exchanges which are necessary to the improved modes of production resorted to as population becomes dense, which may seem to offer examples in point. A moment’s reflection, however, will show that these exceptional cases are not in point.
[21] As may be seen from the map in H. H. Bancroft’s “Native Races,” the State of Vera Cruz is not one of those parts of Mexico noticeable for its antiquities. Yet Hugo Fink, of Cordova, writing to the Smithsonian Institute (Reports 1870), says there is hardly a foot in the whole State in which by excavation either a broken obsidian knife or a broken piece of pottery is not found; that the whole country is intersected with parallel lines of stones intended to keep the earth from washing away in the rainy season, which show that even the very poorest land was put into requisition, and that it is impossible to resist the conclusion that the ancient population was at least as dense as it is at present in the most populous districts of Europe.
[22] I take these figures from the Smithsonian Report for 1873, leaving out decimals. MM. Behm and Wagner put the population of China at 446,500,000, though there are some who contend that it does not exceed 150,000,000. They put the population of Hither India at 206,225,580, giving 132.39 to the square mile; of Ceylon at 2,405,287 or 97.36 to the square mile; of Further India at 21,018,062, or 27.94 to the square mile. They estimate the population of the world at 1,377,000,000, an average of 26.64 to the square mile.
