[95] Dr Johnson was not far wrong in saying that “life declines from thirty-five”; though the Autocrat of the Breakfast-table, like Cicero, declares that “the furnace is in full blast for ten years longer.”

[98] The continuity of the phenomenon of growth, and the natural passage from the phase of increase to that of decrease or decay, are admirably discussed by Enriques, in “La morte,” Riv. di Scienza, 1907, and in “Wachsthum und seine analytische Darstellung,” Biol. Centralbl. June, 1909. Haller (Elem. VII, p. 68) recognised decrementum as a phase of growth, not less important (theoretically) than incrementum: “tristis, sed copiosa, haec est materies.”

[100] As Haller observed it to do in the chick (Elem. VIII, p. 294): “Hoc iterum incrementum miro ordine ita distribuitur, ut in principio incubationis maximum est: inde perpetuo minuatur.”
[101] There is a famous passage in Lucretius (v. 883) where he compares the course of life, or rate of growth, in the horse and his boyish master: Principio circum tribus actis impiger annis Floret equus, puer hautquaquam, etc.
