## Peirce’s 1870 “Logic Of Relatives” • Comment 11.6

Let’s continue working our way through the above definitions, constructing appropriate examples as we go.

$E_1$ exemplifies the quality of totality at $X.$

 (31)

$E_2$ exemplifies the quality of totality at $Y.$

 (32)

$E_3$ exemplifies the quality of tubularity at $X.$

 (33)

$E_4$ exemplifies the quality of tubularity at $Y.$

 (34)

So $E_3$ is a pre-function $e_3 : X \rightharpoonup Y,$ and $E_4$ is a pre-function $e_4 : X \leftharpoonup Y.$
