I have recently applied my invention of Photoglyphic Engraving <1> to copying maps and with very fair success – that is to say for a first attempt – and if you will allow me to send you a few specimens I shall have great pleasure in doing so,
and beg to know where they should if you will inform me where they should be addressed.
The object which I would propose more particularly to apply this little invention is the formation of small partial maps, relative to special localities selected from the large or general maps of any county.
Thus for in The process is so easy that there would be no difficulty for example in mapping the environs of any all the principal towns in England. If these were collated in into a volume with an Index, it would form an atlas of a novel kind, useful to the traveller.
Many other applications will readily occur for instance the parks and seats of the principal nobility as Blenheim, Chatsworth, etc., being all engraved on the same scale, the comparison would be interesting.
1. This was WHFT's improved method for making photographic printing plates. James himself was a pioneer in the use of photozincography.
