liminal

[W]ith the utmost strictness, we excommunicate digamists, as bringing infamy upon the Paraclete by the irregularity of their discipline. The selfsame liminal limit we fix for adulterers also and fornicators; dooming them to pour forth tears barren of peace, and to regain from the church no ampler return than the publication of their disgrace.

If it be assumed […] (2) that the imperceptible value which it [resistance] finally attains is equal to the liminal intensity of the stimulus; and (3) that the intensity of the sensation is proportionate to the magnitude of the area of the circle of irradiation,—the same relation between strength of stimulus, liminal intensity, and intensity of sensation is found as is expressed by 'Fechner's formula' (Maassformel).
