Olefiant gas. Coal gas. Nitrogen is neither paramagnetic nor diamagnetic, and is equivalent to a vacuum. Magnetically considered, it is like space itself, which may be considered as zero. The term _magnetic_ Faraday proposes should be a general one, like that of _electricity_, and include _all_ the phenomena and effects produced by the power, and he proposes that bodies magnetic in the sense of iron should be called _paramagnetic_, so that the division would stand thus: Magnetic ... { Paramagnetic, { Diamagnetic; and it is this division which has been observed in the preceding tables. * * * * * All space above and within the limits of our atmosphere may be regarded as traversed by lines of force, and amongst others are the lines of magnetic force which affect bodies, as shown in the table of paramagnetic and diamagnetic bodies, which have the same relation to each other as positive and negative, or north and south, in electricity and magnetism. The lines of magnetic force are assumed to traverse void space without change; but when they come in contact with matter of any kind they are either concentrated upon it or scattered according to the nature of the matter.
