Summary

Acknowledges letter of 31 August and various works. Regrets he is unable to help GH with his works but will seek to interest Tyndall. Discourages GH on prospect of publication of his new book in England.

Summary

Gustavus Hinrichs is also a [not highly regarded] correspondent of JT’s; he will put GH’s papers on the table at Royal Institution to ease CD’s conscience.

Dined with the Asa Grays at Hooker’s. Told Mrs Gray that CD’s ill health was a benefit because it caused him to ponder a great deal.

Summary

Acknowledges GH’s letter and the lecture on "Faith and science".

Cannot form a judgment on his chemical theory, but if GH establishes his case it will be a magnificent discovery.

"Faith and science" contained many ideas new to CD. Hooker, too, has read it with interest.

Summary

Sends work proving all elements formed of one substance: "Pantogen". Feels affinity with CD. His work will cause as great a stir. Has already been preached against. Asks CD for a note as a token of his sympathy.
