1. Definition and Forms of Inclusion.
By the inclusion of words is meant the extent of their application to objects, not with reference to their numbers, but their kind. Thus stone includes several
hundred species, as trap, limestone, quartz, etc., while onyx includes only stones of a single kind. When we remember that a sign which stands for, or includes, a great. variety of things is as likely to suggest one as another of them, the question of inclusion becomes of the greatest importance to the economy of interpreting power.
With reference to their inclusion, words may be divided into three classes : (1) those which refer to things as members of a species or of a genus, or Specific and General Words; (2) those which, without a change of form, stand for entirely different classes of things, or Homonyms ; and (3) those which closely resemble other words, or Analogues. We shall consider these three classes separately.
