December 11th, 1870.

Sir,—

I am negotiating for a debate with the Rev. Mr. Matthias, of Merthyr, and I am under the impression that the dates you mention for our discussion will be the same as those I have given for my visit to Wales. I expect to know in a few days, when I will again write you.

As to place I am not particular. London will suit me. I suggest the New Hall of Science, unless you have a more suitable hall in view.
