My dear Sir,

The three specimens of maps from plates engraved by the photoglyphic process are very encouraging, and I feel pretty certain of ultimate success – I send a photograph of Hill features which were drawn on a six-inch impression, from which you will see the sort of drawing which we should prepare for the photoglyphic process – the outline would be previously engraved, and with the writing [illegible] on the Scales required – If there is no secret about the photoglyphic process which you do not wish to disclose at present, I should like to know how it is done. Is there any account of it printed?

Yours truly
H. James.
