been freely consulted and extracted from, full credit being given in each case to the author or journal. As this art has of late advanced so rapidly it has been a special aim to give everything that has been printed up to the time of publication. The different parts of the work are arranged in what seemed their logical order, corresponding closely to that followed by Deville. The Appendix contains an account of laboratory experiments, etc., several of which, it is trusted, may be of value. In conclusion, the author wishes to thank the faculty of his " Alma Mater," Lehigh University, for their permission to use his Thesis on Aluminium as the basis of this treatise; also, to acknowledge his indebtedness to Dr. Wm. H. Greene, of Philadelphia, for assistance rendered in the preparation of the work for the press. PHILADELPHIA, November 25, 1886. J. W. R. LIST OF REFERENCES.
