Letters from Dr. J. G. in defence of his Essay on the difference of the relation between motive and action, and that of cause and effect in physics: with replies by A. Crombie.

Mark Twain once famously said "there was but one solitary thing about the past worth remembering, and that was the fact that it is past and can't be restored."  Well, over recent years, The British Library, working with Microsoft has embarked on an ambitious programme to digitise its collection of 19th century books.

There are now 65,000  titles available  (that's an incredible 25 million pages) of material ranging from works by famous names such as  Dickens, Trollope and Hardy as well as many forgotten literary gems , all of which can now be printed on demand and purchased right here on Amazon.

Further information on The British Library and its digitisation programme can be found on The British Library website.
