The readers of the editor’s second enlarged edition of the Hon. R. D. Owen’s Moral Physiology, are apprized that since the publication of his first edition of this work, considerable opportunity has been afforded by the sale of the _Electro-Galvania_ alluded to in this work, for testing its efficacy as a preventive of conception. Time is required to test the effect and establish the certainty of every new remedial agent. Sufficient opportunity has been afforded in this instance, since this instrument was first introduced to public notice, for proving the certain control which the electrical influence is capable of exercising over the nervous system. The increased demand for the instrument has demonstrated its perfect adaption to the accomplishment of the important object for which it is designed, and has most fully established its claim to the confidence heretofore reposed in its preventive influence. Communications from abroad, and orders for this work or the article herein alluded to, addressed to Dr. R. Glover, New York, will meet with due attention. ----- Footnote 1: The Greeks and Romans considered that by familiarizing the population with the exhibition of the human figure completely naked, libidinous propensities and desires would be less excited. The continence and chastity of the half-clad Germans, Tacitus highly extols, and contrasts with the effeminate and luxurious habits of the more polished nations of his time. The worship of the Phallus, or erect penis, is of the most remote antiquity, and derived its origin not from vulgar or obscene notions, but from a consideration that the generative powers of nature were thus best personified; and to render the type more complete, the Deities were often made Hermaphroditic or of a two-fold sex, to show that either alone would be incomplete without the other, to represent nature engendering and reproducing. The Phallus was also used as an amulet or charm suspended from the neck, and its exhibition over a house in Pompeii is explained by the words “domus felicitatis.” On this interesting subject, Mr. O’Brien’s learned, but too fanciful work, on the Round Towers of Ireland, will throw considerable light.
