And if that be true which is delivered by many, and we shall further experiment, that a decoction of Toad-stools if poured upon earth, will produce the same again: If Sow-thistles will abound in places manured with dung of Hogs, which feeds much upon that plant: If Horse-dung reproduceth oats: If winds and rains will transport the seminals of plants; it will not be easie to determine where the power of generation ceaseth. The forms of things may lie deeper then we conceive them; seminal principles may not be dead in the divided atoms of plants: but wandering in the ocean of nature, when they hit upon proportionable materials, may unite, and return to their visible selves again. But the prudence of this Animal is by knawing, piercing, or otherwise, to destroy the little nebbe or principle of germination. Which notwithstanding is not easily discoverable; it being no ready business to meet with such grains in Ant-hils; and he must dig deep, that will seek them in the Winter. CHAPTER XXVIII Of some others. [Sidenote: _Of the Chicken._] That a Chicken is formed out of the yelk of the Egg, was the opinion of some Ancient Philosophers. Whether it be not the nutriment of the Pullet, may also be considered: Since umbilical vessels are carried unto it: Since much of the yelk remaineth after the Chicken is formed: Since in a Chicken newly hatched, the stomack is tincted yellow, and the belly full of yelk, which is drawn in at the navel or vessels towards the vent, as may be discerned in Chickens within a day or two before exclusion. Whether the Chicken be made out of the white, or that be not also its aliment, is likewise very questionable: Since an umbilical vessel is derived unto it: Since after the formation and perfect shape of the Chicken, much of the white remaineth. Whether it be not made out of the grando, gallature, germ or tred of the Egg, as, _Aquapendente_ informeth us, seemed to many of doubt: for at the blunter end it is not discovered after the Chicken is formed; by this also the yelk and white are continued, whereby it may conveniently receive its nutriment from them both. Now that from such slender materials, nature should effect this production it is no more then is observed in other animals; and even in grains and kernels, the greatest part is but the nutriment of that generative particle, so disproportionable unto it. [Sidenote: _Of Eggs._] A greater difficulty in the doctrine of Eggs, is, how the sperm of the Cock prolificates and makes the oval conception fruitful, or how it attaineth unto every Egg, since the vitellary or place of the yelk is very high: Since the ovary or part where the white involveth it, is in the second region of the matrix, which is somewhat long and inverted: Since also a Cock will in one day fertilate the whole racemation or cluster of Eggs, which are not excluded in many weeks after.
