Late 18th century hymns and psalms

You never know what'll turn up next ...

A donation of two old bound volumes is proving very interesting.  The first is a collection of late 18th century hymns and psalm tune publications - and an abbreviated Messiah for pianoforte or organ and voices!  Published in Dublin, who knows where they've spent the past 212 years or so before ending up in the Whittaker Library at the Royal Conservatoire of Scotland?
Before 'Whittaker' gets over-excited, he's off to have a quick coffee, then it'll be time to catalogue the second volume.
