JH on the prospects of meeting WW and Cordelia Whewell. He encloses a photograph 'which for sharpness of finish - faithful graduation of light...[and] general effect is I think you will admit not equalled. The process is a new one...and is at once the easiest, simplest and cheapest which has yet been devised. - As yet I have not yet become familiar with all the details of fixing, transferring etc but that will come of course'. JH hopes soon to produce pictures in absolute black and white.
