 The modified small-pox—that is to say, small-pox that has been robbed of its virulence by the patient having been either already vaccinated, or by his having had a previous attack of small-pox—is ushered in with severe symptoms, with symptoms almost as severe as though the patient had not been already somewhat protected either by vaccination or by the previous attack of small-pox—that is to say, he has a shivering fit, great depression of spirits and debility, malaise, sickness, headache, and occasionally delirium. After the above symptoms have lasted about three days, the eruption shows itself. The immense value of the previous vaccination, or the previous attack of small-pox, now comes into play. In a case of unprotected small-pox, the appearance of the eruption aggravates all the above symptoms, and the danger begins; while in the modified small-pox, the moment the eruption shows itself, the patient feels better, and, as a rule, rapidly recovers. The eruption of modified small-pox varies materially from the eruption of the unprotected small-pox. The former eruption assumes a varied character, and is composed, first of vesicles (containing water), and secondly of pustules (containing matter), each of which pustules has a depression in the center, and thirdly of several red pimples without either water or matter in them, and which sometimes assume a livid appearance. These "breakings-out" generally show themselves more upon the wrist, and sometimes up one or both of the nostrils. While in the latter disease—the unprotected small-pox—the "breaking-out" is composed entirely of pustules containing matter, and which pustules are more on the face than on any other part of the body. There is generally a peculiar smell in both diseases—an odor once smelt never to be forgotten.

Now, there is one most important remark I have to make,—the modified small-pox is contagious. This ought to
