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.

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.
