A Letter to the Right Honourable the Earl of Derby / on the cruelty and injustice of opening the Crystal Palace on the Sabbath

The author addresses a political leader to condemn plans to open a major leisure venue on the Sabbath, arguing the measure offends religious conscience and undermines public morality. He presents the proposal as a gratuitous concession to commercial interests and situates it within wider governmental habits of sacrificing principle for profit. Scriptural injunctions and historical precedents are invoked to warn of social and political consequences when the day of rest is desecrated. The pamphlet accuses the minister of hypocrisy for professed religiosity yet supporting the change, and urges protection of Sabbath observance as essential to national well-being.
