John Playfair (1748-1819) was a Scottish mathematician and geologist best known for his defence of James Hutton's geological theories. He attended the University of St Andrews, completing his theological studies in 1770. In 1785 he was appointed joint Professor of Mathematics at the University of Edinburgh, and in 1805 he was elected Professor of Natural Philosophy. This highly influential book, first published in 1802, contains Playfair's clarification and summary of Hutton's geological concepts. Playfair concisely explains Hutton's theories on erosion and geothermal heat in rock formation and the concept of uniformitarianism in geology, illustrating these theories with his own precise observations on different types of rock strata. The clarity of Playfair's explanations was instrumental in popularising Hutton's geological theories, many of which are now recognised as key principles of modern geology. Playfair's strident defence of Hutton's ideas formed part of a controversial debate between Hutton's supporters and his detractors
The first six books of the Elements of Euclid : in which coloured diagrams and symbols are used instead of letters for the greater ease of learners by John Playfair( Book )

This title presents the elements of Euclid in living color. This is a rare and beautiful geometry primer from the 19th century. In 1847, Charles Whittingham of the Chiswick Press published an extraordinary edition on Euclidean geometry, authored by an obscure mathematician called Oliver Byrne. As Surveyor of Her Majesty's Settlements in the Falkland Islands, Byrne had already published mathematical and engineering works, but never anything like this. Written and designed by Byrne to simplify Euclid's propositions, this remarkable example of Victorian printing has been described as one of the oddest and most beautiful books of the 19th century. Each proposition is set in Caslon italic, with a four line initial: the rest of the page is a unique riot of red, yellow and blue: on some pages letters and numbers only are printed in color, sprinkled over the pages like tiny wild flowers, demanding the most meticulous register: elsewhere, solid squares, triangles and circles are printed in gaudy and theatrical colors, attaining a verve not seen again on the pages of a book until the era of Dufy, Matisse and Derain

"When I ventured to undertake the task of contributing a Preliminary Dissertation to the Encyclopædia Britannica, my original intention was, after the example of Jean le Rond D'Alembert, to have begun with a general survey of the various departments of human knowledge. The outline of such a survey, sketched by the comprehensive genius of Francis Bacon, together with the corrections and improvements suggested by his illustrious disciple, would, I thought, have rendered it comparatively easy to adapt their intellectual map to the present advanced state of the sciences; while the unrivalled authority which their united work has long maintained in the republic of letters, would, I flattered myself, have softened those criticisms which might be expected to be incurred by any similar attempt of a more modern hand. On a closer examination, however, of their labours, I found myself under the necessity of abandoning this design. Doubts immediately occurred to me with respect to the justness of their logical views, and soon terminated in a conviction that these views are radically and essentially erroneous. Instead, therefore, of endeavouring to give additional currency to speculations which I conceived to be fundamentally unsound, I resolved to avail myself of the present opportunity to point out their most important defects;defects which, I am nevertheless very ready to acknowledge, it is much more easy to remark than to supply. The critical strictures which, in the course of this discussion, I shall have occasion to offer on my predecessors, will, at the same time, account for my forbearing to substitute a new map of my own, instead of that to which the names of Bacon and D'Alembert have lent so great and so well-merited a celebrity; and may perhaps suggest a doubt, whether the period be yet arrived for hazarding again, with any reasonable prospect of success, a repetition of their bold experiment. For the length to which these strictures are likely to extend, the only apology I have to offer is the peculiar importance of the questions to which they relate, and the high authority of the writers whose opinions I presume to controvert. It is necessary to comprehend, in one general scheme, all the various departments of study; to arrange them into proper classes; and to point out their mutual relations and dependencies. Such a scheme is sometimes likened by D'Alembert to a map or chart of the intellectual world; sometimes to a Genealogical or Encyclopedical Tree, indicating the manifold and complicated affinities of those studies, which, however apparently remote and unconnected, are all the common offspring of the human understanding. For executing successfully this chart or tree, a philosophical delineation of the natural progress of the mind may (according to D'Alembert) furnish very useful lights"--Introduction.
