eyes, blindness, loss of eyelashes, scrofula, deafness—indeed, a long catalogue of loathsome diseases. A medical man, of course, will be careful to take the cow-pox matter from a healthy child.
49. Would it not be well to take the matter direct from the cow?
If a doctor be careful—which, of course, he will be—to take the matter from a healthy child, and from a well-formed vesicle, I consider it better than taking it direct from the cow, for the following reasons: The cow-pox lymph, taken direct from the cow, produces much more violent symptoms than after it has passed through several persons; indeed, in some cases, it has produced effects as severe as cutting for the small-pox; besides, it has caused, in many cases, violent inflammation and even sloughing of the arm. There are also several kinds of spurious cow-pox to which the cow is subject, and which would be likely to be mistaken for the real lymph. Again, if even the genuine matter were not taken from the cow exactly at the proper time, it would be deprived of its protecting power. 50. At what age do you recommend an infant to be first vaccinated?
When he is two months old, as the sooner he is protected the better. Moreover, the older he is the greater will be the difficulty in making him submit to the operation, and in preventing his arm from being rubbed, thus endangering the breaking of the vesicles, and thereby interfering with its effects. If small-pox be prevalent in the neighborhood, he may, with perfect safety, be vaccinated at the month's end; indeed, if the small-pox be near at hand, he must be vaccinated, regardless of his age and regardless of everything else, for small-pox spares neither the young nor the old, and if a new-born babe should unfortunately catch the disease, he will most likely die,
