The article now universally known as fi'ankincense is the resin called thus, a common, inodorous article, little better than common white resin. which discovery led to the theory of "equivalents." He was appointed Pro- fessor of Chemistry at Owens College, Manchester, in 1851, and there developed the process of making water gas. Be- coming Professor of Chemistry in the Royal School of Mines in 1865 he turned his attention to water analysis, the puri- fication of sewage and the means of preventing pollution. Subsequently he proved that compressed gases are ca- pable of giving out a flame of constant FRANKFORT-ON-THE-MAIN The article once so highly valued, and which, with gold and myrrh, was deemed a gift to lay before the Saviour, must have been some other drug. FRANKLAND, SIR EDWARD, an ii^nglish chemist; born in Churchtown, England, in 1825; studied chemistry in the Museum of Practical Geology and in Germany under Bunsen. He made the discovery of the union of organic radicles with metals, announcing in 1850 the preparation of compounds of zinc with methyl and ethyl. From this he deduced the conclusion that an atom of the metal could only attach itself to a definite number of the atoms of other elements, spectrum, from which he concluded that the photosphere of the sun was atmos- pheric. He also investigated the chemis- try of foods. He died in Norway, Aug. 11, 1899. FRANKLAND, PERCY FARADAY. a British scientist.
