equal, and never have attached the least value to the fact, that when persons put their hands _lightly_ upon tables, _their hands always follow the motion of the table, whichever way the table moves_. It certainly appeared to us a very _significant_ fact, when we first saw the performance, and if considered in connection with electricity, or the _new fluid_, is sufficiently anomalous to require a careful analysis. But more of this anon, as we propose to examine the rappings first. This imposture originated with two girls, by the name of Fox, from Rochester, New-York, who are now, with their mother, travelling through the country, and exhibiting their art for money. A few weeks ago, the Fox-mother gave us an account of this wonderful development of noises or rappings about the two daughters, and from her we learned that the noises were kept up for a long time before they discovered the cause. At first they were annoyed by them, but, _after a while_, they became so familiar with the sounds, that they took but little notice of them, until they discovered the mode of communicating with their authors, and ascertained that the sounds were made by spirits of the departed. According to her account, the spirits then rapped at points remote from the girls, but it seems that the spiritual habit has changed somewhat, for since the girls have been on exhibition,[2] the spirits rap nowhere except directly _under the girls, and about their feet_, or upon something with which their persons or dresses are in contact. We had no desire to see these creatures, except to discover the precise means by which they made the raps, and although fully prepared to condemn them before we paid them a visit, we preferred not to condemn them unseen, lest, on that ground, the clique of rappers should have some advantage over our argument.
