    with hemorrhages from internal origans. They occur in scorbutus, purpura haemorrhagica; in severe acute infectious diseases, especially pyemia, small-pox, and scarlet fever; in acute phosphorus-poisoning and acute yellow atrophy of the liver; and in all severe cachexia;. 2. Witliout internal Jieni07'rhagcs, as a condition limited to the skin : in peliosis rheumatica \i. e. purpura occurring with severe pain in the extremities]; also as small petechiae; almost constantly in typhus fever,^ often in measles and scarlet fever; moreover, on the legs when the convalescent patient first stands up, especially after typhoid fever; and in badly nourished persons where they have been bitten by pediculi. 3. In Diarked venous stasis, local as well as general.^ Here belong those punctiform extravasations of blood which are occasionally seen on the face, particularly on the temples, after severe epileptic and eclamptic convulsions and after severe attacks of whooping-cough. More frequently occur here extravasations of blood in the conjunctiva. 4. As traumatic Jieviori'liages in and under the skin. They are sometimes of importance for determining the occurrence of an injury, especially upon the skull. 4. Scars.—These are often important marks for limiting or ex- plaining the clinical history, which, by reason of the scars, can be confined to past local or general diseases or to injuries received. Thus come under consideration pock (small-pox) marks and the scars which may remain after the different scrofulous and syphilitic dis- eases of the skin and deeper organs, especially the bones and glands. In internal medicine scajs from injuries have importance in many nervous diseases (injuries upon the head, the spine, in the course of peripheral nerves). Here also belong the scars of pregnancy—stricB upon the lower part of the abdomen and the upper part of the thigh. Exactly the same scars occur in marked edema,^ and also sometimes in very fat persons. 5. Bctasia Venarum.— Varices.—Visible nets of veins properly belong here, but they will be described in the section on The Cir- culatory Apparatus. E. Edfema of the Skin and Subcutaneous Cellular Tissue (Edema, Anasarca). By these terms we designate an abnormal, marked saturation of the tissues with fluid, which fluid remains wholly or in part distributed in the cellular meshes and lymph-spaces of the tissues, instead of a cor- responding quantity of fluid existing in bulk, as its transudation takes place from the blood-vessels to be removed by the lymph-current. Edema is recognized by puffiness of the skin causing increase of volume of the affected part, and hence, also, the normal outline on the limbs and the trunk are obliterated in consequence of the filling up of the depressions and cavities, and, moreover, there is a tendency to an equal roundness. The skin is smooth, generally slightly shining, and hence, when the edema is marked, very pale in consequence of the ^ See Roseola. ^ See Cyanosis. ^ See the following section.
