Description

Twelve ?gelatine print photomicrographs taken in ultra-violet light, mounted in a two-ply, cut-away card mount, and captioned and inscribed in manuscript. The mount is of highly acidic card and is very badly decayed; part of the fixing is sellotape. The photographs are very early examples of ultra-violet photomicrography.
