**SYNTHESIS**  
- The newly created @drexel_historical_collection links the medical correspondence subdirectory (homeopathic case studies, @correspondence_journal, @spigelia, @case_* documents) with the academic/administrative subdirectory (faculty conduct letter, @faculty_conduct, @diploma_signing concepts).  
- Persons such as @c_hering appear across multiple source types (author of case studies and archival note) and are now connected to the overarching collection.  
- Geographic references from the metadata (Allentau, Surinam, Germany, St. College) are unified under the collection’s @associated_place relationship, showing the collection’s multi‑regional scope.  
- The collection’s subject list synthesizes themes from both domains, illustrating how Drexel’s historical holdings integrate medical homeopathy and university governance documents.
