My dear Sir,
Having the Egyptian photographs free again, I beg now to propose that if you can kindly come here, say on Saturday at 3 P.M., the oxy-hydrogen lantern shall be ready to show them to you on the screen. Or if that time should not suit, will you kindly mention any hour on any day next week,- and I shall be equally happy to put myself at your service,
and remain, Yours very truly
