Everybody likes to receive a postcard from a friend, but what to do with them once they've been read? These notes were slipped inside books and forgotten, until now.
The first image shows a postcard of the Mull of Kintyre. The postcard was sent to Dr. A. Young at the Aberdeen Royal Infirmary in 1960. It was found tucked inside a copy of the Handbook of Bacteriology by Joseph W. Bigger (London, Bailliere, Tindall & Cox, 1949). These details can be seen on the rear of the postcard.
A short note regarding poisoning from the 1800s and was found in Traité de Toxicologie Générale by J. Anglada (Paris, 1835). The note appears to be in the handwriting of William Mackenzie, a prominent Scottish ophthalmologist of the 19th century.
The final two images are of a postcard, addressed to Mr Hugh Dunbar, is signed by "JGC", who regrets he is unable to attend a meeting (1933). The postcard fell out of a book during a conservation survey in 2002.
