Individual terms are conceived to denote individual objects falling under a general term.  Peirce uses upper case Roman letters for individual terms, for example, individual horses <math>\mathrm{H}, \mathrm{H}^{\prime}, \mathrm{H}^{\prime\prime}</math> falling under the general term <math>\mathrm{h}\!</math> for ''horse''.

The path to understanding Peirce's system and its wider implications for logic will often be smoothed by paraphrasing his notations in contemporary mathematical formalisms, preserving the semantics as much as possible.  Preserving Peirce's orthography while adding a parallel set of conventions will, however, require close attention to typography-in-context.  Current stylings in mathematical texts dictate italics for all mathematical variables, with capital letters for sets and lower case letters for individuals.
