It will of course be understood that the tune appointed for each hymn is printed directly above it, all four parts being given at length, the two trebles printed in a not unusual way upon one staff, the tenor and bass having each separate lines. Therefore no difficulty in singing the hymns can be felt even by the inexperienced, especially as one stanza is printed with the notes to show the exact adaptation. In fine, "Church Pastorals" is a work worthy of an extended circulation and capable of great usefulness. It can serve every purpose of public worship, for it embraces all services of the Sabbath congregation or the week-day gathering, and it touches upon all thoughts and feelings of religious assemblies; it is not above the tastes and abilities of an earnest congregation, nor beneath the notice and use of the independent choir. More than this, it has a particular value for the home and the fireside. Every household knows some quiet hour when the family-voices seek to join in the happy harmony of some unpretending hymn, and when the only limit to such grateful music is the failure of memory or the meagreness of the library, which furnishes only the hymns, or, giving the tunes, supplies only a part of the words,--for few families possess both sorts of books in plenty for their convenient use. This volume offers all,--the hymn, solemn, hopeful, sad, or jubilant, and united to it a tune, perhaps remembered from recollection's earliest days, perhaps unknown and untried, but suiting well the spirit of the words, and ready at an instant's desire to express the sentiment or emotion that rises for utterance. If "Church Pastorals" had no other merit, this alone would make it worth possessing by all who love and ever practise sacred music. A thorough and elaborate index includes in one ingenious list all references, whether to hymns, tunes, or metres; and the inaccuracies which will creep into even as handsome typography as this are unimportant, and rectified as quickly as observed. The size is convenient, and the shape comely. _Illustrations of Progress_: A Series of Discussions by HERBERT SPENCER. With a Notice of Spencer's "New System of Philosophy." New York: D.
