After travelling in Siberia, he became Professor of Chemistry in the University of St. Petersburg. Hied 30th Nov. 1850. [Poggendorff’s Handworterbuch.] August Friedrich Horstmann, Hon.

He succeeded his father as a brewer, but after misfortunes in business, received, in 1878, a Civil List pension. Fie died at Sale, 11th Oct. 1889. [Obituary, Journ. Chem. Soc., 57, 449 (1890).] Jean Charles Galissard de Marignac was born at Geneva, 24th April 1817. He studied in Paris, and after a year’s travel in the north of Europe, entered Liebig’s laboratory at Giessen. Here he worked on naphthalene and phthalic acid, his first and last essay in organic chemistry. He became Pro¬ fessor of Chemistry in the Academy at Geneva, and subse¬ quently also Professor of Mineralogy. The Academy developed into the University, and Marignac came into occupation of a fine laboratory. In 1878 the condition of his health obliged him to retire, and he established for himself a laboratory in his own house. He died on 15th April 1894. Marignac determined with great accuracy the atomic weights of a large number of elements. He devoted many years to the investigation of the earths of the cerite group, and dis¬ covered ytterbia. About 1870 Marignac proved the isomor¬ phism of the fluoxyniobates with the fluo-salts of tin and tungsten, and established the formulae of niobic (columbic) and
