New Fragments. By John Tyndall, F.R.S. (Longmans.)—It is needless to
say that there is some excellent reading in this volume. Professor Tyndall discourses on the " Sabbath," a lecture de- livered, not without courage, considering its contents, in Scotland ; on Goethe's " Farbenlehre " (theory of colours) ; on Count Rum- ford (Benjamin Thomson), the Founder of the Royal Institution ; on Louis Pasteur ; and, not to speak of other subjects, on Thomas Young. The name will, it is probable, suggest little to many readers. Nevertheless, Thomas Young was a man of extraordinary versatility of genius. An eminent classical scholar, a great mathematician, a physicist of no small eminence, a physician of repute, he crowned the edifice of these remarkable achievements by his discoveries in the interpretation of Egyptian hieroglyphics, —discoveries for which he has hardly received his due share of credit. Professor Tyndall makes a most interesting story out of his career. Not the least interesting of the Fragments is that which contains the writer's reminiscences of Carlyle, of whom he saw much in his later days. We must not forget to mention the " Alpine Jottings," highly attractive descriptions of mountain experiences.
