some so small that they may be easily concealed. Some I have ground into oval forms to be hung at watches; and some, for the curious, I have set in wedding rings, that ladies may never want an attestation of their innocence. Some I can produce so sluggish and inert, that they will not act before the third failure; and others so vigorous and animated, that they exert their influence against unlawful wishes, if they have been willingly and deliberately indulged. As it is my practice honestly to tell my customers the properties of my magnets, I can judge, by their choice, of the delicacy of their sentiments. Many have been content to spare cost by purchasing only the lowest degree of efficacy, and all have started with terror from those which operate upon the thoughts. One young lady only fitted on a ring of the strongest energy, and declared that she scorned to separate her wishes from her acts, or allow herself to think what she was forbidden to practise.
I am, &c.
