A Test of Love.
Reading edition
Put into a phial some sulphuric ether, color it red with alkanet, then saturate the tincture with spermaceti. This preparation is solid ten degrees above freezing point, and melts and boils at twenty degrees. Place the phial which contains it in a lady’s hand and tell her that if in love, the solid mass will dissolve. In a few minutes the substance will become fluid.
