Case 43 — Magnetism and rate: record evidence before naming a cause · source wording exercise

Correction note for “Magnetism and rate: record evidence before naming a cause”: retain the wording beginning “A competent watchmaker can test and diagnose it; random adjustment…” in the record. If later material changes it, add the date, the changed wording and the source for that change; do not invent a completed correction here. Retain the source wording beside any paraphrase.
