To Robert Hunt   31 July [1855]

Down Farnborough Kent

July 31st

My dear Sir

I had hoped to have had no occasion to have troubled you again by letter, but the enclosed1 throws me quite back.— Will you be so kind as to read it over, & tell me what I must answer. I have not the least idea, whether glass coated with colour or coloured throughout makes any difference. Will you be so kind as to let me have one line in answer, & return the enclosed.—

I asked whether they had (& the price of)

  • 1. “intense cobalt Blue”
  • 2. “silver yellow”
  • 3. “deep copper red”

& used your name & stated that my object was to experimentise on plants.—

Pray forgive this trouble | Yours truly obliged | Charles Darwin


The enclosure has not been found. It is clear, however, that it was a query from the Chance Brothers Glass Works, Birmingham. CD must have written to the firm, as Hunt had suggested, about coloured glass for his experiments. See letter from Robert Hunt, 24 July 1855.


Mentions experiments on plants involving coloured glass. Encloses correspondence from glass maker and asks advice.
