The psalter contained all 150 psalms in their entirety, though obviously many of them were too long to be sung whole. In 1781 a selection of 67 paraphrases of Scripture was given permissive use for a year. Although never officially adopted, the paraphrases had significant use in succeeding years, mainly in the lowlands. Five hymns were inserted at this time without church authority. Reflecting a move from the simplicity and plainness of earlier Scottish worship in some later editions there was also a set of seven trinitarian doxologies ("To Father, Son and Holy Ghost..."), each for a different metrical pattern, which could be sung at the close of a psalm. These were printed together at the end of the psalms, and were intended to allow the Old Testament text to be sung in the light of the New.
