Index Guide
The numbers refer to the headings under which the words or phrases occur. When the same word or phrase can be used in various senses, the several headings under which it, or its synonyms, will be found are indicated by Italics. These words in Italics are not intended to explain the meaning of the word or phrase to which they are annexed, but only to assist in the required reference.   1
  Italicized references within parentheses are merely suggestive, the parentheses indicating that the term itself is not included in the list referred to.   2
  When the word given in the Index Guide is itself the title or heading of a category, the reference number is printed in bold-face type, thus: abode 189.   3
  To keep the Index Guide—necessarily very large—from becoming unwieldy, a considerable number of obsolete, rare, foreign, dialectic, and slang terms has been omitted; for such words, while useful in the text, are not the ones for which synonyms would ordinarily be sought.   4
  Derivatives likewise have been sparingly admitted, since the allied or basic term will serve as a key to the various derived forms; thus, cold is given, but not coldness and coldly. By such means, unnecessary duplication is avoided.   5
