Cadaverous Faces.
This is an amusing contrast to the lighting-up by means of magnesium; Again let the room be nearly darkened. Put about a tea-cupful of spirits of wine in a strong common dish or saucer, and place the dish in the middle of the table. Let every one approach to the distance of about a yard. Then ignite the spirit with a match. It will burn with a peculiar yellowish-blue flame, and in the light of this the human countenances, and all objects of similar color, lose their natural tint, and look spectral. The contrast of the wan and ghostly hue with the smiling lips and white teeth of those who look on, is most amusing. The effect of this experiment is heightened by dissolving some common table-salt in the spirit, and still further by putting into it a small quantity of saffron. Let the spirit burn itself away.
