Most of the vesicles are unilocular and collapsewhen they are pricked. They are rarely, if ever, confluent. The clearserum of the vesicle becomes cloudy and within twenty-four or thirty-six hours begins to dry so that a scab is formed. The vesicles appearin crops even in the same locality. Hence, papules, new vesicles, didvesicles, and scabs may be found in the same patient a few days afterthe onset. The attack is usually at its height on the third or fourthday and the acute symptoms are passed within a week or ten days,but the scabs frequently do not all fall before the end of the third weekand sometimes later. Fio. 117. Chickenpox. Symptomatology. Temperature.—The fever of varicella is extremelyvariable. In mild cases there is often none whatever. Usually thereis slight elevation of temperature for one or two days and not infre-quently, in the more severe cases, the fever continues for four or fivedays or even longer. It is usually intermittent in type and may ran<rebetween 99° and 102° or 103° F. In the more severe but rare casesit may reach 104° F. It seems to me impossible to present a chartthat could be called typical of varicella. Eruption.—The lesions of the typical eruption have been well describedas looking as if drops of hot water had fallen upon the skin and raised VARICELLA 543 small, round blisters, with a narrow, inflamed zone around each. Whenthe skin is thick, as on the palms and soles, there is no red zone, thevesicle lying alone in the normal skin. The contents of the vesiclesis at first clear and soon becomes cloudy, but not purulent unless th
