[177] Idque non solum in ovo, sed in omni fœtu, animaliumque conceptu primo contingere, mox palam fiet. Harvey: On Generation, Editio princeps, 149, l. 33-35. In the Opera Omnia, 390, l. 1-3, a comma has been erroneously placed between "conceptu" and "primo"; the latter word qualifies "conceptu," not "contingere." Compare Op. Omn. 391, l. 4: in primis animalium conceptibus.
[178] In primis animalium conceptibus.

[182] 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.
