Description

Copy of letter, copied as part of the correspondence project led by Colonel John Herschel FRS following the death of his father. Thanks Robert Hunt for his 'extensive and instructive view on the present state of photography.' Found many interesting results in experimenting with vegetable substances. Surprised by Robert Hunt's discovery that bi-chromate of potash is a photographic substance; John Frederick William Herschel nearly achieved this result.
