John Keble, M.A., in a tract addressed to English churchmen and churchwomen, Against profane dealing with holy matrimony with regard to a man and his wife's sister, proved to be unscriptural and a false alarm in a letter to the Rev. Charles B. Dalton, M.A - Jenkinson, John Simon (J. Hatchard and Son, 1849)
