Thus, of one of the idols at Copan, ‘The intention of the sculptor seems to have been to excite terror.’ Stephens's Central America, vol. i. p. 152; at p. 159, ‘The form of sculpture most generally used was a death's head.’ At Mayapan (vol. iii. p. 133), ‘representations of human figures or animals with hideous features and expressions, in producing which the skill of the artist seems to have been expended;’ and again, p. 412, ‘unnatural and grotesque faces.’

The most constant gland in the animal kingdom is the liver.’ Grant's Comp. Anat. p. 576. See also Béclard, Anat. Gén. p. 18, and Burdach, Traité de Physiol. vol. ix. p. 580. Burdach says, ‘Il existe dans presque tout le règne animal;’ and the latest researches have detected the rudiments of a liver even in the Entozoa and Rotifera. Rymer Jones's Animal Kingdom, 1855, p. 183, and Owen's Invertebrata, 1855, p. 104.

Until the analysis made by Demarçay in 1837, hardly any thing was known of the composition of bile; but this accomplished chemist ascertained that its essential constituent is choleate of soda, and that the choleic acid contains nearly sixty-three per cent. of carbon. Compare Thomson's Animal Chemistry, pp. 59, 60, 412, 602, with Simon's Chemistry, vol. ii. pp. 17–21.

282

‘The size of the liver and the quantity of the bile are not proportionate to the quantity of the food and frequency of eating; but inversely to the size and perfection of the lungs… The liver is proportionately larger in reptiles, which have lungs with large cells incapable of rapidly decarbonizing the blood.’ Good's Study of Medicine, 1829, vol. i. pp. 32, 33. See Cuvier, Règne Animal, vol. ii. p. 2, on ‘la petitesse des vaisseaux pulmonaires’ of reptiles.

Indeed it has been supposed by M. Gaëde that the ‘vaisseaux biliares’ of some insects were not ‘sécréteurs;’ but this opinion appears to be erroneous. See Latreille, in Cuvier, Règne Animal, vol. iv. pp. 297, 298.

‘La prédominance du foie avant la naissance’ is noticed by Bichat (Anatomie Générale, vol. ii. p. 272), and by many other physiologists; but Dr. Elliotson appears to have been one of the first to understand a fact, the explanation of which we might vainly seek for in the earlier writers. ‘The hypothesis, that one great use of the liver was, like that of the lungs, to remove carbon from the system, with this difference, that the alteration of the capacity of the air caused a reception of caloric into the blood, in the case of the lungs, while the hepatic excretion takes place without introduction of caloric, was, I recollect, a great favourite with me when a student… The Heidelberg professors have adduced many arguments to the same effect. In the fœtus, for whose temperature the mother's heat must be sufficient, the lungs perform no function; but the liver is of great size, and bile is secreted abundantly, so that the meconium accumulates considerably during the latter months of pregnancy.’ Elliotson's Human Physiology, 1840, p. 102. In Lepelletier's Physiologie Médicale, vol. i. p. 466, vol. ii. pp. 14, 546, 550, all this is sadly confused.

286

‘The liver is the first-formed organ in the embryo. It is developed from the alimentary canal, and at about the third week fills the whole abdomen, and is one-half the weight of the entire embryo… At birth it is of very large size, and occupies the whole upper part of the abdomen… The liver diminishes rapidly after birth, probably from obliteration of the umbilical vein.’ Wilson's Human Anatomy, 1851, p. 638. Compare Burdach's Physiologie, vol. iv. p. 447, where it is said of the liver in childhood, ‘Cet organe croît avec lenteur, surtout comparativement aux poumons; le rapport de ceux-ci au foie étant à peu près de 1:3 avant la respiration, il était de 1:1.86 après l'établissement de cette dernière fonction.’ See also p. 91, and vol. iii. p. 483; and on the predominance of the liver in fœtal life, see the remarks of Serres (Geoffroy Saint-Hilaire, Anomalies de l'Organisation, vol. ii. p. 11), whose generalization is perhaps a little premature.

287

This diminution of casualties is undoubtedly one cause, though a slight one, of the increased duration of life; but the most active cause is a general improvement in the physical condition of man: see Sir B. Brodie's Lectures on Pathology and Surgery, p. 212; and for proof that civilized men are stronger than uncivilized ones, see Quetelet, sur l'Homme, vol. ii. pp. 67, 272; Lawrence's Lectures on Man, pp. 275, 276; Ellis's Polynesian Researches, vol. i. p. 98; Whately's Lectures on Political Economy, 8vo. 1831, p. 59; Journal of the Statistical Society, vol. xvii. pp. 32, 33; Dufau, Traité de Statistique, p. 107; Hawkins's Medical Statistics, p. 232.

The general social consequences of this I shall hereafter consider; but the mere economical consequences are well expressed by Mr. Mill: ‘Of the features which characterize this progressive economical movement of civilized nations, that which first excites attention, through its intimate connexion with the phenomena of Production, is the perpetual, and, so far as human foresight can extend, the unlimited, growth of man's power over nature. Our knowledge of the properties and laws of physical objects shows no sign of approaching its ultimate boundaries; it is advancing more rapidly, and in a greater number of directions at once, than in any previous age or generation, and affording such frequent glimpses of unexplored fields beyond, as to justify the belief that our acquaintance with nature is still almost in its infancy.’ Mill's Principles of Polit. Economy, vol. ii. pp. 246–7.

What this horrible disease once was, may be estimated from the fact, ‘qu'au treizième siècle on comptait en France seulement, deux mille léproseries, et que l'Europe entière renfermait environ dix-neuf mille établissemens semblables.’ Sprengel, Histoire de la Médecine, vol. ii. p. 374. As to the mortality caused by the plague, see Clot-Bey, de la Peste, Paris, 1840, pp. 62, 63, 185, 292.

290

For a curious list of famines, see an essay by Mr. Farr, in Journal of the Statistical Society, vol. ix. pp. 159–163. He says, that in the eleventh, twelfth, and thirteenth centuries, the average was, in England, one famine every fourteen years.

291

In the opinion of one of the highest living authorities, famine is, even in the present state of chemistry, ‘next to impossible.’ Herschel's Discourse on Natural Philosophy, p. 65. Cuvier (Recueil des Eloges, vol. i. p. 10) says that we have succeeded ‘a rendre toute famine impossible.’ See also Godwin on Population, p. 500; and for a purely economical argument to prove the impossibility of famine, see Mill's Principles of Political Economy, vol. ii. p. 258; and compare a note in Ricardo's Works, p. 191. The Irish famine may seem an exception: but it could have been easily baffled except for the poverty of the people, which frustrated our efforts to reduce it to a dearth.
