Perceival Street, Clerkenwell, Aug. 28, 1842.
Dear Sir—In reference to your application, I recollect visiting you at your apartments in Wigmore street, early in July, 1840, when you showed me the model of your electro magnetic printing telegraph, with which you printed my name at the time. You also showed me a model of your electro magnetic clock, and explained to me the principles and utility of them.
I remain, dear sir, yours, respectfully,
ROBERT C. PINKERTON.
