Folding Plates, Leather Binding
Collated, lacking plates II-IV and therefore only containing plate I. The 'Philosophical Magazine and Journal of Science' is one of the oldest scientific journals published in English. This is volume XX of the 'New and United Series of the Philosophical Magazine, Annals of Philosophy and Journal of Science' which covers January-June of 1842. Articles of note to this edition are Professor Grove's 'On a Voltaic Process for Etching Daguerrotype Plates', 'On the Magnetic Influence of the Lunar Spectrum in relation to a New Theory of Terrestrial Magnetism', Mr J Bryce's 'Notice of the Discovery of some remains of the Ichthyosaurus in Ireland', Mr R King on 'The Unexplored Coast of North America' and Professor de Morgan's 'On The Invention of the signs + and - and on the sense in which the former was used by Leonardo da Vinci.' De Morgan is the namesake for the propositional logic and boolean algebraic laws 'De Morgan's Laws. There are several articles by De Morgan in this volume such as 'Additional Note on the History of Fernel's Measure of a Degree'' and 'On Fernel's Measure of a Degree, in reply to Mr Galloway's Remarks'. There are numerous articles to this work on barometers, elements, coral reefs, the geological society, meteorological observations and more. A truly fascinating and important work regarding scientific development and discoveries in the mid nineteenth century boasting numerous articles of all areas of science.
