My dear Sir

I have no objection to make the affidavit ² in the general terms you mention; but it appears to me that it would be necessary to show that the parties against whom you proceed have actually infringed the processes described in your patents; in this case it would be much better to have the affidavits of practical chemists who are accustomed to patent trials as Prof Brande, ³ Prof. Miller ⁴ of King’s College or Prof. Graham. ⁵ I shall be at the Atheneum ⁶ on Wednesday next at 5 o’clock, perhaps I may see you there.

Yours very truly
C. Wheatstone
