Royal Institution <1>
26 May 1834
Dear Sir
I am not prepared either to agree or deny your reasoning. I am in doubt whether the action is of the direct chemical kind which you consider it but the doubt arises more from general notions than any particular reason and I have not time to think the subject over so as to say into what opinion of the causes which operate in the experiment I should finally settle <2>
I am Yours Truly
