Noad, Author of Lec- tures on Chemistry, &lc. London: George KniglU & Sons, Foster Lane. Mr. Noad has published a new edition of his Lectures on Electri- city, which give succinctly an account of each department of elec- trical science, with the forms of illustrative experiments and the history of the mi)st recent discoveries and improvements. In peru- sing this work we have seen v/ith gratification how much Dr. Faraday has contributed to every branch of these sciences, and we thought we could not give a much better example of the value of Mr. Noad's book, nor a more interesting selection for our readers, than to extract some account of Dr. Faraday's valuable labours. It will not he forgotten that it was by means of an apparatus, in some de- gree resembling the Electrophorus in principle that Faraday succeeded in demonstrating that induction is essentially a physical action, occurring be- tween contiguous particles, and never taking place at a distance without polarizing the molecules of the intervening dielectrics. The conclusion seems to be that induction is not through the metal of the apparatus, but through the air in curved lines. In fact, as Mr. Noad puts it, it is an action of the contiguous particles of the insulating body thrown into a state of polarity and tension, and capable of communicating their forces in all directions. With regard to the theory of electro-chemical decomposition, in his second ecture, page 77, Mr. Noad remarks— "The following beautiful experiments, made by Faraday (See Exp. Research, series v. 462 et seq.), prove that, so far from electro-chemical decomposition depending upon the
