Note 67 — XI THE LAW OF NATURE

As, for instance, in Pliny the Elder’s ascription to the lower animals of moral sentiments (Hist. Nat. viii. 5; viii. 16, 19; x. 52). Michael Drayton’s lines, of birds pairing in spring,—

‘And but that Nature by her all-constraining law,

Each bird to her own kind this season doth invite,’—

hover between Ulpian’s ‘Law of Nature’ and the ‘Laws of Nature’ of modern science.
