Note 182 — Chapter VI
Reading edition
The "point" is the embryonic heart, to which in its earliest visible state the name of "punctum saliens," i.e., "leaping point," had been given, this technical term having been coined no doubt out of expressions used by Aristotle in speaking of the living rudimentary heart as seen with the naked eye in the hen's egg and in mammalian abortions. Compare Aristotle: History of Animals, 561a, 6-17; On the Parts of Animals, 665a, 33 to b, 2.
