    and nerves, and of the viscera, are considered separately under Injuries of Si^ecial Tissues and Organs. Treatment.—Beyond placing the part at rest, and applying an evaporating or a spirit lotion, nothing more as a rule is required, as the extravasated blood presses upon the injured vessels, and so prevents further htemor- rhage. Should a hsematoma form, it should on no account be opened, as the blood will usually become absorbed; whilst, if air be admitted, suppuration will probably ensue. Aspii-ation, however, when the ha?ma- toma is very large, may occasionally be done with advantage. BUEXS AXD SCALDS. BuEiS'S AJXD SCALDS vary in their effect according to their depth, extent, situation, and the age of the patient. An extensive though superficial burn on the trimk, head, or face, especially in a child, may be more serious than a deeper but limited burn on the extremities. A burn is usually said to be more severe than a scald, as the fluid prodn.cing the latter generally quickly cools and runs olf. A scald, however, owes its severity to the large extent of surface usually implicated, and when produced by molten metal or boiliiig-oil which adheres to the part is generally very serious. Burns and scalds, when severe, give rise to constitutional as well as local effects. The local effects may be considered under Dupnytren's division of burns into six degi-ees. These degrees, howcvir, may be variously combined in the same biu-n. IsTDEOiucE.—Hiiiijih' crythinnt. due to increased flow of blood through the dilated vessels. No tissue destruc- tion ensues, and no scar is left. 2XD DEGHEE.— Vcsicalioiiy due to the exudation from the dilated capiUaries of the cutis causing the snjjcrticial layers of the cpithelinni to be raised from the dee]icr in the form of blebs. No scar is left, as only the superficial lavers of tlio ejnlhelinm arc destroyed, and tlieso are soon reproduced from the deeper layers. Some sliglit staining ot the skin, liowevcr. may subseiinently remain. ;iin) DK(iliEE.—Iksiniclion vf /Ac cidii-Jc <(ii(l jxirt of Ihc irii<■ d-iiu-ThQ epithelinm around the Lair-follicles, in thii sweat-<rlands, and between the papilLv, osca]ies. and ra])id]y forms new epithelium over the granulating surface left on the separation of the slough.
