Has been commissioned by Guillaume Weber to present a paper about an instrument for measuring the earth's magnetism, to JH. Would like to present it personally; when can he call?
Asks JH to sign an affidavit that WT is the inventor of the calotype or talbotype as some are trying to break WT's patent hold.
