Because this is the sort of book that interests me greatly, I assumed that I must have purchased it somewhere long ago and subsequently forgot about it. But I couldn't imagine that I would neglect to remember such a thing. However, when I looked inside the cover, I found my wife's handwriting. It turns out that she had purchased the volume during her studies in Cambridge, England, in 1987, and it sat unnoticed in our library for all the years of our marriage.
William Howley, well known for his opposition to the Great Reform Act of 1832 and Catholic emancipation. Our copy is the 34th edition, printed in 1851. Here is a link to an online copy, though this is of the 30th edition from 1847. Of special interest to me is that this volume indicates that metrical psalms were still being sung in Church of England parishes as late as the middle of the 19th century. Nowadays metrical psalmody is chiefly associated in the popular mind with the Dutch and Scottish churches, while Anglican churches typically chant the prose versions of the Psalms. But metrical psalmody once had an apparently secure presence in England as well.
The title's reference to the "Old Version" is to Sternhold & Hopkins' complete psalter of 1562. The "New Version" is Nahum Tate and Nicholas Brady's Psalter of 1696, which gradually replaced the former before it too eventually fell out of general usage.
At the beginning of this little volume is an index appointing psalms and hymns to be sung for every Sunday of the church year, along with some special weekdays. Not surprisingly, Psalm 51 is prescribed for Ash Wednesday and 118 for Easter, in accordance with ancient western tradition. However, Psalm 51, rather than Psalm 25, is appointed for the first Sunday in Advent, and Psalm 104 is missing from Pentecost, or Whitsunday. The psalms and hymns are divided between morning and evening prayers, while the Lord's Supper makes only one appearance and is treated as a special occasion rather than a regular Sunday service. I don't know the extent to which this collection was actually used in the churches, but the fact that it went through so many editions—and virtually every year—suggests widespread popularity. When it finally went out of print I cannot say, but the latest online edition is from 1856, and an ancillary volume referencing it dates from 1859.
With one consent let all the earth
to God their cheerful voices raise;
Glad homage pay with awful mirth
and sing before him songs of praise.
