Note g — Chapter II · (continued 2)

‘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.
