Poor Common Salt!


“SOME books are lies frae end to end”, says Burns. Scientific (save the mark) speculation would seem to be on the way to this state! Thus on p. 405 of NATURE, of Sept. 17, in a letter on Prof. Lewis's light corpuscles, the statement is made by the writer, that a ‘speculation,’ by Prof. Lewis, about the quantum, “is repugnant to common sense”. Again, on p. 414, Prof. W. L. Bragg asserts that “In sodium chloride there appear to be no molecules represented by NaCl. The equality in number of sodium and chlorine atoms is arrived at by a chess-board pattern of these atoms; it is a result of geometry and not of a pairing-off of the atoms”.
