When small type is selected for foot-notes that may be of unequal length, the notes may be put in half measure. The space between the two columns should not be wider than the em quad of the type of the note, and may be still narrower. The halfmeasure note saves space in turned-over lines, and presents a neater appearance than that made by the straggling lines of the broad measure, with its frequent gaps of white produced by short lines that sometimes contain one syllable only. The note in half measure may show an uneven number of lines in the two parallel columns, but the gap of white space at the end (sometimes nine tenths of the broad measure) is not so offensive in the half measure, for by that treatment the blank must be less than that of some over-turns of a broad measure.

The use of half measure for notes gives to them a distinction that they do not have when set in a broad measure, and it differentiates them from the
