Morphologische Untersuchungen auf dem Gebiete der indogermanischen Sprachen, volume 1 (preface)

evidence

Supports the attribution of the exceptionless-sound-law doctrine to the Neogrammarian programme stated in this preface. V55 verification basis: this session had no access to any source — WebFetch was egress-blocked for every host attempted and the WebSearch budget was exhausted before authoring — so the cited work was not retrieved, and no page, volume or figure quoted from it was re-checked. The doctrine is paraphrased in English; no German sentence is quoted and no translation is reproduced, because the text was not consulted.

A evidence is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
