It has not been in the power of the writer to see a single page of the proof sheets. He has sent off chapter after chapter, as soon as it was off his hands. These hints, besides being in part an apology for repetitions and incongruities, will lead the reader to make due allowance for any other errors he may notice. If this little volume, prepared under many embarrassments, shall prove of any service to the Kingdom of Christ, it is enough. D. M. G. New York, May 1, 1851.
