You will see very readily that the main point of difference between yellow jaundice and pigmentary atrophy is in the color, and also in the fact that the cells in yellow jaundice are in their normal state and in pigmentary atrophy are in a contracted condition. The treatment given for yellow jaundice as follows: injecting and washing the blood vessels with a mild solution and the application to the affected parts of a strong bleaching solution, should be given for pigmentary atrophy. The suggestions as regarding the lights to show the body under, should also be noted and used in these cases. (c) =Cancerous Spots.=—What is intended for this particular discoloration, is not the ordinary cancer that has eaten through the skin, but that form sometimes noted in aged persons where the cancer is just about to come through the skin. In other words, a yellowish brown color showing in any of the exposed parts of the skin before death. As cancer is in fact a rottening or mortification of the tissues, the injection with a hypodermic outfit of a strong hardening and bleaching solution will harden and bleach out the color of the cancer to a great extent, and thus improve the appearance greatly, the ordinary cosmetic powders will finish the preparation. For the hypodermic injection we would suggest the following: R Alum, 10 gr. Corrosive sublimate, 5 gr. Zinc chloride, 5 gr. Grain alcohol, 4 fluid oz. Formaldehyde, 2 fluid oz. The cancerous spot should not be confounded with the color of dessication which will resemble it somewhat. The main point of difference would be that the cancer would be present before death, and the dessication could not possibly occur until after the body is embalmed. This caution is advised on account of the tendency the solution to be injected hypodermically would have to make a dried spot worse in color than better. (d) =Gangrene.=—Gangrene can best be described as the death of certain areas of tissue of the living body. The death of the tissue may be brought about by very many causes; by vascular obstruction and arrest of the blood supply to a part, or of the outflow from a part; by enfeebled circulation; temporary stoppage of the circulation of a part or organ; acute infection; and by burns. Gangrene with its peculiar color, a dark green, is not often found on the exposed surfaces of the body, but will more often be found on the lower extremities and then only on the bodies of aged persons. For this reason it will be unnecessary to treat it for the removal of color. (e) =Ecchymosis, or Antemortem Staining.=—Ecchymosis is an extravasation of blood into the areolar tissues, forming a bruised place caused principally by a blow from a heavy instrument or missile. This form of discoloration is mostly seen in accident cases, where death was due to mechanical causes.
