Uneven spacing in the same line is without excuse. When three-to-em spaces do not fill the measure they must be supplanted with en quadrats or two five -to -em spaces. When three-to-em spaces are too much they should be changed for four- to -em or five-to-em spaces. In composition by hand this change of spaces should be evenly done between all words as far as the irregular forms of meetingletters will allow.
It is always desirable to have a little blank at the end of a paragraph to show more plainly the ending of the last line of that paragraph, but this last line should not be spaced closer or wider than the preceding line.
LEAN AND FAT TYPES NOT SPACED ALIKE
A fat letter of fifteen or more ems to the alphabet will bear much wider spacing than a thin letter of twelve ems or less. Condensed letter, on the contrary,
should be thin-spaced invariably. The proper space between words in any type is fairly indicated by the blanks between the stems of the letters m and n of that type, which will be wide in fat and narrow in lean type, and should be a safe guide for the determination of correct spacing.
