A series of events will be held at the University of St Andrews to mark the 200th anniversary of the birth of Charles Darwin.
Charles Darwin's signature appears on a letter sent in October 1844 to James David Forbes (1809 - 1868), an eminent Scottish scientist in the field of glaciology.
From 1859 Forbes was Principal of the United College of St Salvator and St Leonard at the University of St Andrews.
Darwin tells Forbes of his observations of parallel lines and the effects of glacial ice, and offers to send him specimens of Mexican obsidian.
The University of St Andrews Special Collections owns the entirety of Forbes' library of books, manuscripts and correspondence.
February 2009 marks the bicentennial of Charles Darwin and 150 years of "On the Origin of Species", one of the most influential books of the 19th century.
This very special occasion will be celebrated all over the world, and St Andrews is no exception. A series of events will take place from the 9th-12th of February.
