Unfortunately for, the experimental philosophy of the female to whose protecting care Oliver Twist was delivered over, a similar result usually attended the operation of _her_ system; for at the very moment when the child had contrived to exist upon the smallest possible portion of the weakest possible food, it did perversely happen in eight and a half cases out of ten, either that it sickened from want and cold, or fell into the fire from neglect, or got half-smothered by accident; in any one of which cases, the miserable little being was usually summoned into another world, and there gathered to the fathers it had never known in this.
