How was the face of corpse?

From the text:

It was the dead body of a woman. It lay very lightly on the water, and the face was sweet and calm. It was not a beautiful face; it was too prematurely aged-looking, too thin and drawn, to be that; but it was a gentle, lovable face, in spite of its stamp of pinch and poverty, and upon it was that look of restful peace that comes to the faces of the sick sometimes when at last the pain has left them.
