vol. i. p. 28) assures us that ‘the Egyptians, for especial purposes, were endowed with great wisdom and science.’ Science properly so called, the Egyptians had none; and as to their wisdom, it was considerable enough to distinguish them from barbarous nations like the old Hebrews, but it was inferior to that of the Greeks, and it was of course immeasurably below that of modern Europe.

Indeed many of them are still unknown; for, as M. Rey justly observes, most writers pay too exclusive an attention to the production of wealth, and neglect the laws of its distribution. Rey, Science Sociale, vol. iii. p. 271. In confirmation of this, I may mention the theory of rent, which was only discovered about half a century ago, and which is connected with so many subtle arguments that it is not yet generally adopted; and even some of its advocates have shown themselves unequal to defending their own cause. The great law of the ratio between the cost of labour and the profits of stock, is the highest generalization we have reached respecting the distribution of wealth; but it cannot be consistently admitted by anyone who holds that rent enters into price.

In a still more advanced stage, there is a fourth division of wealth, and part of the produce of labour is absorbed by rent. This, however, is not an element of price, but a consequence of it; and in the ordinary march of affairs, considerable time must elapse before it can begin. Rent, in the proper sense of the word, is the price paid for using the natural and indestructible powers of the soil, and must not be confused with rent commonly so called; for this last also includes the profits of stock. I notice this, because several of the opponents of Ricardo have placed the beginning of rent too early, by overlooking the fact that apparent rent is very often profits disguised.

‘Wages depend, then, on the proportion between the number of the labouring population, and the capital or other funds devoted to the purchase of labour; we will say, for shortness, the capital. If wages are higher at one time or place than at another, if the subsistence and comfort of the class of hired labourers are more ample, it is, and can be, for no other reason than because capital bears a greater proportion to population. It is not the absolute amount of accumulation or of production that is of importance to the labouring class; it is not the amount even of the funds destined for distribution among the labourers; it is the proportion between those funds and the numbers among whom they are shared. The condition of the class can be bettered in no other way than by altering that proportion to their advantage; and every scheme for their benefit which does not proceed on this as its foundation, is, for all permanent purposes, a delusion.’ Mill's Principles of Political Economy, 1849, vol. i. p. 425. See also vol. ii. pp. 264, 265, and M'Culloch's Political Economy, pp. 379, 380. Ricardo, in his Essay on the Influence of a Low Price of Corn, has stated, with his usual terseness, the three possible forms of this question: ‘The rise or fall of wages is common to all states of society, whether it be the stationary, the advancing, or the retrograde state. In the stationary state, it is regulated wholly by the increase or falling-off of the population. In the advancing state, it depends on whether the capital or the population advance at the more rapid course. In the retrograde state, it depends on whether population or capital decrease with the greater rapidity.’ Ricardo's Works, p. 379.

The standard of comfort being of course supposed the same.

‘No point is better established, than that the supply of labourers will always ultimately be in proportion to the means of supporting them.’ Principles of Political Economy, chap. xxi. in Ricardo's Works, p. 176. Compare Smith's Wealth of Nations, book i. chap. xi. p. 86, and M'Culloch's Political Economy, p. 222.

The division of food into azotized and non-azotized is said to have been first pointed out by Magendie. See Müller's Physiology, vol. i. p. 525. It is now recognised by most of the best authorities. See, for instance, Liebig's Animal Chemistry, p. 134; Carpenter's Human Physiology, p. 685; Brande's Chemistry, vol. ii. pp. 1218, 1870. The first tables of food constructed according to it were by Boussingault; see an elaborate essay by Messrs. Lawes and Gilbert on The Composition of Foods, in Report of British Association for 1852, p. 323: but the experiments made by these gentlemen are neither numerous nor diversified enough to establish a general law; still less can we accept their singular assertion, p. 346, that the comparative prices of different foods are a test of the nutriment they comparatively contain.

‘Of all the elements of the animal body, nitrogen has the feeblest attraction for oxygen; and, what is still more remarkable, it deprives all combustible elements with which it combines, to a greater or less extent, of the power of combining with oxygen, that is, of undergoing combustion.’ Liebig's Letters on Chemistry, p. 372.

The doctrine of what may be called the protecting power of some substances is still imperfectly understood, and until late in the eighteenth century, its existence was hardly suspected. It is now known to be connected with the general theory of poisons. See Turner's Chemistry, vol. i. p. 516. To this we must probably ascribe the fact that several poisons which are fatal when applied to a wounded surface, may be taken into the stomach with impunity. Brodie's Physiological Researches, 1851, pp. 137, 138. It seems more reasonable to refer this to chemical laws than to hold, with Sir Benjamin Brodie, that some poisons ‘destroy life by paralysing the muscles of respiration without immediately affecting the action of the heart.’

Prout's well-known division into saccharine, oily, and albuminous, appears to me of much inferior value, though I observe that it is adopted in the last edition of Elliotson's Human Physiology, pp. 65, 160. The division by M. Lepelletier into ‘les alimens solides et les boissons’ is of course purely empirical. Lepelletier, Physiologie Médicale, vol. ii. p. 100, Paris, 1832. In regard to Prout's classification, compare Burdach's Traité de Physiologie, vol. ix. p. 240, with Wagner's Physiology, p. 452.

The evidence of an universal connexion in the animal frame between exertion and decay, is now almost complete. In regard to the muscular system, see Carpenter's Human Physiology, pp. 440, 441, 581, edit. 1846: ‘there is strong reason to believe the waste or decomposition of the muscular tissue to be in exact proportion to the degree in which it is exerted.’ This perhaps would be generally anticipated even in the absence of direct proof; but what is more interesting, is that the same principle holds good of the nervous system. The human brain of an adult contains about one and a half per cent of phosphorus; and it has been ascertained, that after the mind has been much exercised, phosphates are excreted, and that in the case of inflammation of the brain their excretion (by the kidneys) is very considerable. See Paget's Lectures on Surgical Pathology, 1853, vol. i. pp. 6, 7, 434; Carpenter's Human Physiology, pp. 192, 193, 222; Simon's Animal Chemistry, vol. ii. p. 426; Henle, Anatomie Générale, vol. ii. p. 172. The reader may also consult respecting the phosphorus of the brain the recent very able work of MM. Robin et Verdeil, Chimie Anatomique, vol. i. p. 215, vol. ii. p. 348, Paris, 1853. According to these writers (vol. iii. p. 445), its existence in the brain was first announced by Hensing, in 1779.

Though both objects are equally essential, the former is usually the more pressing; and it has been ascertained by experiment, what we should expect from theory, that when animals are starved to death, there is a progressive decline in the temperature of their bodies; so that the proximate cause of death by starvation is not weakness, but cold. See Williams's Principles of Medicine, p. 36; and on the connexion between the loss of animal heat and the appearance of rigor mortis in the contractile parts of the body, see Vogel's Pathological Anatomy of the Human Body, p. 532. Compare the important and thoughtful work of Burdach, Physiologie comme Science d'Observation, vol. v. pp. 144, 436, vol. ix. p. 231.
