Note zzz — BOOK IV.
Reading edition
There is manifestly a superintending Providence in this Case, that some Animals are able to suck as soon as ever they are born, and that they will naturally hunt for the Teat before they are quite gotten out of the Secundines, and parted from the Navel-String, as I have seen. But for Chickens, and other young Birds, they not being able immediately to pick till they are stronger, have a notable Provision made for such a Time, by a part of the Yolk of the Egg being inclosed in their Belly, a little before their Exclusion or Hatching, which serves for their Nourishment, till they are grown strong enough to pick up Meat. Vid. Book VII. Chap. 4. Note (a).
