Patent Office Museum correspondence

Patent Office Museum correspondence, chiefly by Bennet Woodcroft. These seven volumes include copy letters from Woodcroft and originals of incoming letters. Each has an alphabetical name index, including some subject indexing, at the front (24/I has much more comprehensive subject indexing). Each has calendaring of letter content at the end of the volume, but for 24/I this ends at 1877 Jul 24]
