Wells, Marcus Morris, is the author of one of our most popular modern hymns on the Holy Spirit and also the composer of the tune to which it is universally sung. Beyond the published date of his birth (1815) and his death (1895) and the statement that he was a lawyer living in the State of New York, we have no facts concerning him. It is hoped that some facts may be learned about him which may be incorporated in later editions of this volume. The date assigned to the hymn by Mr. Ira D. Sankey is 1858. It is to be regretted that we have not other hymns and tunes from one who can write devotional poetry and music such as that represented by the single hymn and tune which we have here from his pen.
