    tlieresult of :—1. Injmy, of ten slight, inflicted on parts the vitality of which is already lowered by poor li^ang, ad- vancing age, and chronic congestions due to vaiicose veins, long-standing, &c. 2. Certain morlDid states of the system, siich as are indiiced by syphilis and struma. 3. Pressure, especially when conjoined with a defective nerve-supply; as an example of which may be mentioned bedsores occurring in cases of injury to the spinal cord. The treatment of ulceration varies according to the local condition of the ulcer and the constitutional state of the patient, andwillbe discussed under Varieties of Ulcers. All that need be said in general is, that the cause should if possible be removed, all sources of irritation avoided, the constitutional state of the patient treated with appropriate remedies, and such dressings applied as are indicated by the local condition of the xdcev. Diseases of cicatrices.—After an ulcer has healed over and the granulation tissue has been convertecl into fibrous tissue, this latter continues to shrink, leading to obliteration of the blood vessels in the cicatrix and causing contraction and often distortion of the sui-- rounding parts. Cicatrices differ from normal skin in that they are devoid of sweat-ducts, hair-follicles, sebaceous glands, and lymphatics, and being also butpoorly supplied with nerves and vessels, are very apt_ to break down on slight provocation leading to a re-opening of the ulcer. Moreover, owing to their unstable nature they are liable to undergo certain changes and become the scat of keloid, o]nthelioma and warty excrescences, and to be at- tended with itching, pain, and intense neuralgia.
