A Scientific Instrument
Carte de visite by an anonymous photographer. A man poses next to a scientific instrument of unknown origins. It is housed in a tapered glass container topped by a spool and hand crank. A right angle and compass propped up against the container obscures a word, perhaps “patent,” which suggest this may be a patent model. If true, the man may be its inventor.
