A Lecture to Young Men, on Chastity: Intended Also for the Serious Consideration of Parents and Guardians
Sylvester Graham’s own pamphlet on chastity and the dangers of masturbation, first delivered as a lecture in 1834 and reissued in further editions; this is the fourth edition, published in Boston by George W. Light in 1838. The Wellcome Collection holds a full digitized copy (work id k8j7cb55) under a Public Domain Mark, confirmed directly via the Wellcome Collection API, which also confirms the physical description (246 plus 6 pages, 12mo) and publication details (“Boston (Mass.): G.W. Light, 1838”). The archive cites it as the primary-source statement, in Graham’s own words, of the masturbation-insanity claim central to the case’s vague-mechanism stage, and uses its title page (verified by direct visual inspection of the digitized page images, which set out the full title, the author’s name, the fourth-edition statement, and the imprint, matching the catalog record exactly) as the case’s artifact media asset.
