esicle, then a pustule, and lastly it forms a scab or crust. The variouschanges form so many stadia ot unequal duration. The first or stage of papule, lasts from twenty-four to twenty-eight hours. The second or vesicular stage lasts four days. The last stage, or that of scabbing, lasts three days more, making the wholeduration of the normal pustule ten or eleven days. There are varieties, however, of small-pox, in which the formation ofthe pustule is irregular, as in the Hemorrhagic, confluent and home small-pox. In the home small-pox the two last stages are singularly shortenedor absent altogether. When the eruption of small-pox is of the distinct variety, its first appear-ance consists of a number of small red papules, about the size of a pinshead, more or less numerous, but separate and distinct from one another, ^.__l A.4V U V AR.1V/Urt.

The cells of theRete Malpighii swell up the papillae elongate, and the red spot of skin be-comes a sharply defined nodule, perfectly solid, and having a flattened top. On the second or third day of the eruption, the second stage towards thedevelopment of pustules commences. A small vesicle, which graduallyenlarges, bound down and depressed in the centre, or umbilicated, forms onthe apex of each pimple, by elevation of the outer layer of the epidermis,and contains a clear whey-colored fluid. This vesicular stage lasts almostfour days, when the vesicle maturates or u ripens into a pustule. Thisprocess is so gradual, that if the pustule be examined closely about thetilth or sixth day, a central whitish disc of lymph may be seen, set in orsurrounded by a circle of yeLowish, puriform matter.
