*Confluent Smallpox.*--In this form the vesicles coalesce or run together, forming variously shaped and sized blisters, which as pustulation proceeds are usually ruptured in some manner and become infected, forming large, thick scabs with extensive ulceration underneath. The inability to properly cleanse such cases causes a very fetid odor to be given off and makes the patient an exceedingly difficult one to treat. In the mild confluent form the disease is similar to the discrete form only that several lesions coalesce. In the severe confluent form the coalescence is extensive and large blisters are formed. The swelling about them is intense, and with the extensive sepsis the patient rarely survives. The swelling of the face and extremities is sometimes enormous, and the suffering is so severe as to make death a welcome visitor. Confluent smallpox runs a course similar to that of the other forms, except that it is not as rapid as the third and is usually more severe than the first. *Hemorrhagic Smallpox.*--This is recognized as the malignant form of variola, and is rapidly fatal in most cases. It runs its course precipitately, and at times most unexpectedly,--sometimes killing the patient in a few hours and in other cases not completing its career until the fourth or fifth day. Hemorrhages may come on suddenly and the patient expire before any rash appears. In one case an efflorescence appeared and so closely resembled scarlet fever that it was mistaken for it. Suddenly hemorrhages set in, and within six hours the patient was dead. There was a question at the time as to whether the case was malignant scarlet fever or malignant smallpox. Later a room-mate came down with a typical case of smallpox and helped to clear the doubt. The hemorrhage usually occurs as the disease changes from vesiculation into pustulation. The severity of the hemorrhagic form of the disease is shown by the rapidity with which it passes through the various stages. Macules appear, and within a few hours rapidly change into papules, which almost as rapidly change into pustules; and before pustulation is complete hemorrhage occurs, and death quickly follows. It is not unusual in these cases for the disease to run its course in from twenty-four to thirty-six hours. In many, severe constitutional symptoms mark the onset, hemorrhages occur immediately, and death results before the rash appears. The hemorrhages are from the mucous membrane of the eyes, nose, and mouth, and from the anal, vaginal, and urethral orifices, the membrane swelling enormously. Hemorrhage occurring in the skin causes it to become raised and of a livid purple or bluish tint. The eyes seem to bulge as if about to drop from the orbital cavity. On the abdomen the hemorrhage is beneath the skin, causing raised lesions with a sharp border and a flattened top, feeling dense and firm to the touch. In the peritoneum the hemorrhages are extensive.
