Brief Description: | Experimental photogenic drawing by Sir John Herschel, undated but 1839. The inscription is unusual, as is its position along the top of the front, suggesting a departure from the usual experimental procedures. Subject: engraving, no image Technique: contact copy (print) from a negative Format: inscription horizontal Polarity: positive Orientation: not apparent Quality: no visible image, double border Colour: pale purple or lilac, streaky and blotchy Chemistry: silver based (if the inscription is read as N it would mean silver nitrate), with sodium chloride Coating: none Inscription: seemingly a chemical note Paper: thin Condition: good Purpose: probably a sensitising and positive printing experiment. For fuller descriptive and historical commentary see narratives. | ||||||||||
Primary Inscriptions: | '13. IV + [?]Salt cream + IV + S + IV' along top of front [IV could perhaps be N (nitrate); in Herschel's hand]. | ||||||||||
Provenance: | Presented by Miss Herschel and Lady Lubbock in 1928. They were the two surviving and youngest children of Sir John Herschel (Francisca and Constance). | ||||||||||
