CHASTITY. INTENDED ALSO FOR THE SERIOUS CONSIDERATION OF PARENTS AND GUARDIANS. _Second Edition—Enlarged and Improved, with Notes._ BY DR. SYLVESTER GRAHAM. The second edition of this important work is nearly double the size of the first, although the price is increased but a trifle. It is selling rapidly. Notwithstanding its value is extensively known, we cannot forbear to insert two or three TESTIMONIALS. The following remarks, from the Annals of Education for 1834, are from the pen of WILLIAM C. WOODBRIDGE; whose long and zealous devotion to the cause of education, and whose extensive travels and researches both in Europe and America, and special attention to the subject of which he here speaks, pre-eminently qualify him to judge accurately in the matter: “We are rejoiced to see a work published in our country, on a topic in physiology which the ‘artificial modesty’ to which we have formerly alluded, has covered up, until a solitary, but fatal vice is spreading desolation through our _schools_ and _families_, unnoticed or unknown. The experience of teachers, the case-books of physicians, and the painful exposures which accident, or the dreadful diseases which follow in its train, have occasionally produced, have at length forced it upon public attention; and we hope it will not again be forgotten. The work before us is the result of extensive observation and study; its usefulness has been tested by its influence as a lecture; and its views of this evil are in accordance with the experience of the few teachers whom we have known possessed of the moral courage to encounter it. We would offer it to those who have earnestly desired a work on this subject, as one adapted to their purposes. We would recommend its perusal to every _parent_ and _teacher_. We would warn them that those who have been most confident of the safety of their charge, have often been most deceived; and that the youthful bashfulness which seems to shrink from the bare mention of the subject, is _sometimes_ the blush of shame for concealed crime. We feel bound to add, what abundant and decisive evidence has shown, that ignorance on this subject is no protection from the vice—nay, that it is often the original cause or encouragement of it; that it gives tenfold power to the evil example and influence which are so rarely escaped; and that a cure can be effected only by the most careful instruction and long continued discipline, both physical and moral, directed by sad experience, as is presented in this work.” The following brief but highly valuable testimony is from the distinguished superintendent of the Massachusetts Lunatic Hospital at Worcester: “DEAR SIR:—The subject of your Lecture to Young Men, has been much neglected, although of great importance.
