Autograph Letter Signed to Pryor's mother.

12mo: 3 pp. Good, on lightly-aged paper. Concerns Pryor's posthumous 'Flora of Hertfordshire' (1887), which contained an introduction co-written by Hopkinson. Four copies of the book are being presented to Mrs Pryor 'by our Society'. 'This is partly the cause of the delay in sending them to you, for we had to wait for authority from the Council of the Society, to present them.' The rest of the letter concerns the large paper edition of the book, a copy of which Hopkinson offers to procure for Mrs Pryor 'at the subscription price'. 'As only 50 of these have been printed we decided (at the first) not to give a single copy away, except the one we were bound to send to the British Museum, [...] There is not one of these large paper copies in your family, for Mr. Marlbrough Pryor has only taken a small paper copy & Mr. Robert Pryor has not subscribed at all.'
