During Bolzano in Prague 2014, Wolfgang Künne (On Having a Property. Corrigenda in Bolzano’s Wissenschaftslehre), raised the question of the origin of the term Adhärenz.

One way to approach the question is to use Google’s N-Gram Viewer to search for Adhärenz in the German corpus from 1700 to 1900. This is what we get:

Adhäarenz in the Google German corpus up to 1900


If you click on the 1700-1799 Google search, you get this result:

We find the term Adhärenz predominantly in books in natural philosophy (by authors such as Pierre Prévost), in Basilius von Ramdohr’s Venus Urania (see other versions of the text here), where soul is called an adherence of the I, but also Tittel’s  Locke vom menschlichen Verstande (“zu leichtem und fruchtbarem Gebrauch gergliedert und geordnet von Gottlob August Tittel”) where the context is philosophy of mind. Was any of these works at the origin of Bolzano’s term? Conjectures welcome. Further searches might help further!
