The composition of capital letters only, which are generally twice as high and twice as wide as the round letters of the lower-case series, needs spaces twice as wide as those between lower-case words, and leads twice as thick as those between lowercase lines. The en quadrat is the least permissible space between words set in capitals; two three-toem spaces are better, but the em quadrat may be allowed in a head-line of two-line letter when it is surrounded by much open space.

It is held that this thin space is wide enough to separate words and even sentences, The em quadrat between sentences and the three-to-em space between words are rated as waste white space, and are a vexation to one who admires the mannerisms of medieval copyists. If a sentence ends within the line, omit all space after it; let the capital letter of the new press on the period of the last sentence.
