He had them then into another Room where was a Hen and Chickens, and bid them observe a while. So one of the Chickens went to the trough to drink, and every time she drank she lift up her head and her eyes towards Heaven. See, said he, what this little Chick doth, and learn of her to acknowledge whence your mercies come, by receiving them with looking up. Yet again, said he, observe and look; so they gave heed and perceived that the Hen did walk in a four-fold method towards her Chickens. 1. She had a common call, and that she hath all day long. 2. She had a special call, and that she had but sometimes. 3. She had a brooding note. And 4. She had an out-cry.
