Families in all conditions of life are affected. Much interest was excited in the disease in England from the fact that the late Prince Leopold was a sufferer.
Climate appears to have an influence in determining attacks. Cold, damp, changeable weather is favorable, while a residence in a warm, equable climate diminishes the tendency in a very marked manner. Some patients have an extraordinary susceptibility to changes in the weather.
All observers have noted the great fertility of bleeder families. Those first born seem less liable to bleed than subsequent ones.
SYMPTOMS.—The existence of the defect of constitution may not be suspected until an uncontrollable hemorrhage follows some trivial injury or operation, or a spontaneous bleeding may occur and present great or insuperable difficulties in its arrest. The symptoms usually occur in the first years of life, and in the great majority of cases, as mentioned above, the first bleeding occurs before the fifth year. The symptoms may be grouped under three divisions (Legg, Grandidier): external bleedings, spontaneous and traumatic; interstitial bleedings, petechiæ, and ecchymoses; and the joint affections. Legg recognizes three grades of the disease. The first and most severe is characterized by bleedings of every kind, external and internal, and by troublesome joint affections: this form is most often seen in men. The second grade is less severe; there are spontaneous hemorrhages from the mucous surfaces, but no traumatic bleeding or ecchymoses and no joint troubles: this form is most often seen in women. The third and lowest degree is when there is a tendency simply to ecchymoses; no dangerous bleedings occur: this form is often seen in members of bleeder families, and if in women the menstruation may be early and profuse.
External Bleedings.—The spontaneous bleedings may occur from the skin, the mucous, and in rare instances the serous, membranes. There are frequently preliminary symptoms—prodromata—such as flushing, fulness of the head, and throbbing of the arteries—signs of so-called plethora; often there is irritability of temper, but sometimes, in children, extra cheerfulness has been observed. The localities affected and the frequency are shown by the following analysis of 334 cases by Grandidier: Epistaxis, 169 times; from the mouth, 43; stomach, 15; bowels, 36; urethra, 16; lungs, 17; cerebral hemorrhage, 2; skin of head, 4; tongue and finger-tips, 4 each; tear-papilla, 3; eyelids, 2; external ear, 5; female generative organs, 10; ulcer of skin, 2; navel (long healed), 2. An odd situation for spontaneous bleeding is mentioned by Townsend,171 in which a child bled to death from the scrotum. In many cases these spontaneous hemorrhages prove fatal—most frequently the epistaxis. The traumatic bleeding may result from blows, cuts, scratches, etc., and the blood may be effused into the tissues or discharged externally. Fatal hemorrhages have occurred from the following wounds: blow on head, 11 times; slight scratches on skin or abrasion of dermis; laceration of the frænum of the lip, slight cut (two lines deep) in a duel wound; bite of the tongue (7 cases); fall on the mouth; blow on the nose; blow of a stone on the finger; cut in paring the nail; fall on the head with meningeal hemorrhage (2 cases, brothers); and rupture of the hymen on the wedding-night.

After operations, trivial and severe, many fatal cases have occurred, and the statistics of the same author give the following: cutting of the frænum linguæ, 1; leeching, 5; venesection, 4; blister, 2; extraction of tooth, 12; circumcision, 8; cutting umbilical cord, 4; vaccination, 2; fistula, stone, ligation of carotid, of radial, of ulnar, of femoral arteries, amputation of arm and of thigh, 1 each; phimosis, 2. Leeching, extraction of teeth, and circumcision are most dangerous operations in bleeders.
The bleeding is always a capillary oozing, and the vessels are not seen. It may last for hours, or even many days and weeks, and the amount of blood lost may be enormous. Epistaxis may be fatal in twenty-four hours. In Coates' case a medical student lost half a gallon of blood in twenty-four hours, and in the ten days which the bleeding continued it was estimated that he lost about three gallons.
The healing of a wound in a bleeder may take place rapidly, either with or without suppuration. When the hemorrhage is large or prolonged, severe anæmia follows, from which, as a rule, the patients recover with remarkable rapidity.
The interstitial hemorrhages—petechiæ, ecchymoses, hæmatoma—may be spontaneous or the result of injuries. The petechiæ occur most frequently in the skin, particularly of parts distant from the heart—the legs and arms, less often the face. On the mucous and serous surfaces they are less common. They resemble ordinary purpuric spots, and crops may come out with symptoms of swelling and pain in the joints. Large extravasations—hæmatoma—are most frequently of traumatic origin and may follow the slightest blow, as in a case of Sir Wm. Jenner's, in which from the fall of a rubber ball on the thigh an enormous extravasation took place between the knee and trochanter.172 They are blue, black, or reddish-black at first, and in their absorption go through the various changes in color which we notice in a bruise. These blood-tumors may occasionally arise spontaneously.
