Mary Somerville to Faraday   25 October 1835

How truly I am obliged to you my dear Sir for your kindness¹. The chloride of silver answers perfectly, and I took advantage of the last sunshine to make experiments upon a variety of substances with success. There were some curious results, but time will be required & brighter weather to confirm them. I beg my best regards to Mrs Faraday

and remain yours | very Sincerely | Mary Somerville
