Some days ago I read an article in a site talking about the embalmed head of Henry IV (originally Henri IV).
When I finished to read the article I rapidly started to search about matter to make a forensic approximation. However, how mostly of times, I find few things to work.
The mostly of images found was of the embalmed head. It is difficult to put the tissue depth marks because you can make some mistake and compromising the result of the approximation.
