and soft, and should not be tied up. The tying up of a sleeve makes it hard, and is much more likely to rub the vesicles than if it were put on in the usual way. 56. If the arm, AFTER vaccination, be much inflamed, what ought to be done? Smear frequently, by means of a feather or a camel's-hair brush, a little cream on the inflamed part. This simple remedy will afford great relief and comfort. 57. Have the goodness to describe the proper appearance, after the falling off of the scab, of the arm?
It might be well to remark that the scabs ought always to be allowed to fall off of themselves. They must not, on any account, be picked or meddled with. With regard to the proper appearance of the arm after the falling off of the scab, "a perfect vaccine scar should be of small size, circular, and marked with radiations and indentations."
DENTITION.
58. At what time does dentition commence?
The period at which it commences is uncertain. It may, as a rule, be said that a babe begins to cut his teeth at seven months old. Some have cut teeth at three months; indeed, there are instances on record of infants having been born with teeth. King Richard the Third is said to have been an example. Shakspeare notices it thus:
"York.—Marry, they say my uncle grew so fast
That he could gnaw a crust at two hours old;
'Twas full two years ere I could get a tooth.
Grandam, this would have been a biting jest."
