Bright and joyful is the morn. J. Montgomery. [Christmas.] This popular hymn was contributed to the 8th edition of Cotterill's Selection, 1819, No. 213, in 4 stanzas of 4 lines, and repeated in Montgomery's Christian Psalmist, 1825, No. 489, and his Original Hymns, 1853, No. 17. Its use is somewhat extensive, both in Great Britain and America. The original text is usually given; but sometimes stanza iii., line 2, reads, “Christ, th’Incarnate Deity," for "The Incarnate Deity." It is sometimes dated 1825, in error.
