    of magnetic induction in crystalline and non-crystal- line substances in the Philosophical Magazine, 1851, vol. i. p. 177, as being in all parts in perfect accordance with the various experimental results which 1 have at different times obtained. With respect to Paragraphs 2967. 3242, and the in- tentions there expressed of experimenting with oxygen at low temperatures, I have endeavoured to carry these intentions out; but the extreme difficulty of working on such attenuated matter as gases at low temperatures, without the production of air-currents able to influence the very delicate torsion-balanceand apparatus required to measure the result, is so great as to have prevented me as yet from obtaining any results worthy of confidence. I owe many thanks to the Royal Society and to the Proprietors of the Philosophical Magazine, for the great kindness I have received in the loan of plates, &c., and in other facilities granted to me for the printing of the volume. As the Index belongs both to the Experimental Researches and to the other papers, its references are of necessity made in two ways; those to the Researches are, as before, to the numbers of the paragraphs, and are easily recognized by the greatness of the numbers: the other references are to the pages, and being always pre- ceded by p. or p]p., are known by that mark. MICHAEL FARADAY. January, 1855.
