Put a hair space between the letters of contractions in small capitals:
a.m.[42](ante meridiem), p.m.{42}(post meridiem), should be lower-case, except in lines of caps. or small caps.
When small caps, are used at foot of title-page, print thus:M DCCCC IV[43]
Text references to caps. in plates and woodcuts to be in small caps.
The first word in each chapter of a book is to be in small caps. and the first line usually indented one em; but this does not apply to works in which the matter is broken up into many sections, nor to cases where large initials are used. (Seep. 50as to indentation.)
