1204 OBITUARY NOTICES. 0 B I T U A R Y NOT I C E S . MARSHALL HALL, late Captain in the Royal East Middlesex Militia, born in London on February 6th, 1831, was the only child of Dr. Marshall Hall, the eminent physician and physiologist. H e was educated at Eton and at Caius College, Cambridge, and was sub- sequently called to the Bar, although he never practised as a barrister. I n early youth, he showed a strong liking for scientific pursuits, especially chemistry and mineralogy, his skill in the use of the microscope being of great service to him, especially in his mineralogical investigations. This love of science determined the future course of his life. He contributed several papers, both to the Geological and the Mineralogical Society, and was one of the founders of the latter.He was an ardent mountaineer, and made numerous Alpine excursions in his early days, whilst later on he devoted much time to the study of glaciers; at the international Geological Congress held in Zurich in 1895, he succeeded in getting a committee appointed for a com- parative study of the variations of glaciers in all parts of the globe, he himself being nominated the representative of Great Britain and the Colonies on the committee. He spent much of his time in Switzer- land, residing there with his family from 1878 to 1884, studying the interesting geological and glacial problems which in that country everywhere present themselves. The scientific dredging cruise off the coasts of Spain and Portugal, which he made in 1870 in his yacht “Norna,” in company with Mr.Edward Fielding and Mr. Savile-Kent, is well known. He died suddenly at his residence at Parkstone on April 14th, 1896. He was elected a Fellow of the Chemical Society in 1866; he was also a Fellow of the Geological Society, a member of the Royal Microscopical Society, the Agricultural Society, the Mineralogical Society, the Alpine Club and numerous other societies. HENRY A. MOTT died last year at his residence in New York. He was born at Staten Island in 1852, and graduated at the School ofOBITUARY NOTICES. 1205 Mines, Columbia College, in 1873. He was Professor of Chemistry in the New York Medical College for women, official chemist to the Medico-Legal Society, and well known as an expert in Medical Jurisprudence. A t one time, he acted professionally for the United States Government in examining food products for the Indian Depart- ment.TETSUKICHI SHIMIDZU, M.E., one of our Japanese Fellows, died at Chicago from phthisis on May 8th, 1896, in his 33rd year, after a year’s illness. His father, a sak6 brewer in Mino (Japan), sent him to Tbkya in 1873, when he was only 9f years old, to be educated at the High School there, founded by Mr. Fukuzawa, the leader in education in Japan on European lines. Two years later, he entered the Preparatory School for the Imperial College of Engineering, under English teachers, matriculated in 1877, and in 1883 took the College degree, Master of Engineering, with special distinction, in the subject of Applied Chemistry. For two years he was one of the Instructors in Chemistry in the College of Engineering, and during that time devoted himself to original research, contributing to the Chemical Society, in conjunction with Dr.Divers, the following papers : ‘‘ On Calcium Hydrosul- phides ” ; “Magnesium Hydrosulphide Solution and its Use in Chemico- Legal cases as a Source of Hydrogen Sulphide ” ; “Reactions of Selenious Acid with Hydrogen Sulphide, and of Sulphurous Acid with Hydrogen Selenide ” ; ‘ I The Specific Action of a Mixture of Sulphuric and Nitric Acids on Zinc in the Production of Hydroxylamine”; “ On the Constitution and Reactions of Liquid Nitric Peroxide ” ; “ On the Action of Pyrosulphuric Acid on certain Metals ” ; and “Mercury Sulphites and the Constitution of Sulphites.” Jointly with the same chemist, he was also author of a note in the Chenzical News on the “ Red Sulphur of Japan.” In 1885, he entered the Department of the Japanese Government for Agriculture and Commerce, as Chemist, and as Examiner in the Patent Office of that Department ; and during the six and a half years in which he filled these offices received various marks of the appreciation in which his abilities and services were held.At this time he took an active part in the affairs of the Tbkyii Chemical Society, and also became Secretary of the Japan Society of Engineers, an influential body in matters relating to engineering and technology. His geniality and activity made him fill this position with exceptional success. Early in 1892, he resigned his appointments in the Government service in order to join his friend, Mr.J. Takamink (also one of our Fellows), in America, and established there a factory of Japanese fsrrnents, for use in the manufacture of diastase and alcohol more1206 OBITUARY NOTICES. economically than by malting and ordinary yeast fermentation. The manufacture, protected by several patents (see J, Xoc. Chem. Ind., 14, 55), has attained comparatively large proportions, and Mr. Shimidzu was fully occupied in perfecting the machinery and processes up to the time of his last illness. It was in December, 1886, that he was elected a Fellow of the Chemical Society, a year after he had become a Member of the Society of Chemical Industry. His father died while be was a student. His cheerful, unselfish, and in every way amiable disposition endeared him to many.He was an only child and was unmarried. E. D. WILLIAM HENRY WALENN was born in London, January7th, 1828, and died at his residence, 9, Carleton Road,Tufnell Park, on September 20th, 1896, after a long and painful illness. He was trained as an engineer at the works of Messrs. Cottam, and received part of his education at University College, London, where he studied mathematics under Professor De Morgan. He was one of the earliest abridgers of specifi- cations to the Patent Office, beginning under the then Comptroller, Mr. Woodcroft, for whom he compiled the Series of Abridgments relating to ‘‘ Electricity and Magnetism,” “ Photography,” and other subjects. I n 1866, his book, Little Experiments for Little Chemists,’’ was pub- lished, and in it was given a new process for depositing brass upon zinc.I n 1871, he contributed a paper to the Philosophical Magazine, (( On Solutions for Depositing Copper and Brass by means of Electric Force,” and about the same time he conducted some experiments for the Government in electro-deposition of copper upon the bottom of an iron ship. Between 1868 and 1880, several mathematical papers of his on ‘‘ Unitates,” and methods of checking calculations by means of these,.were published in the P l d Mag. Mr. Walenn was known among his friends as a man always ready aud willing t o aid any in- quirer after scientific truth, whether in his favourite study of mathe- matics, or in the many branches of physics and chemistry with which he was familiar. He became a Fellow of th.e Chemical Society in 1866, and of the Institute of Chemistry soon after its establishment.He was also a member of the Physical Society. THEODOBE GEORGE WORMLEY, M.D., Ph.D., LL.D., Professor of Chemistry and Toxicology in the Medical Department of the Uni- versity of Pennsylvania, died at his home in Philadelphia, January 3rd, 1897, after a comparatively short illness.OBITTJARP NOTICES. 1207 Dr. Wormley was born in Wormleysburg, Pa., on April lsh, 1826. His collegiate education was received at Dickinson College, but he left before the completion of his course in order to study medicine at the Philadelphia Medical College, from which institution he graduated in 1849. I n 1852, he was called to the chair of chemistry and natural sciences at Capital University, Columbus, Ohio, which he held until 1865, and was also Professor of Chemistry and Toxicology in Starling Medical College from 1854 to 1877. On the resignation of Professor Robert E.Rogers in 1877, he was called to the chair of chemistry and toxicology in the medical department of the University of Pennsylvania, which position he held until his decease. During 1867-1875, Dr. Wormley was State Gas Commissioner of Ohio, and in 1867-1874 chemist to the Ohio Geological Survey. The degree of Ph.D. was conferred on him by Dickinson College, and that of LL.D. by Marietta, both in 1870. He was appointed a member of the Centennial Medical Commission having in charge the arrangements for the International Medical Congress of 1876, to which he was a delegate, and he delivered an address before that body on Medical Chemistry and Toxicology. In 1862-1864, he edited the Ohio Medical und Surgicul Journal, and during the years 1859-1863, he published a series of papers in the Chemical News on the chemical reactions of various toxic alkaloids and other organic and inorganic poisons. H e was the author of '' Methods of Analysis of Coals, Iron Ores, Furnace Slags, Fire Clays, Limestones, and of Soils " (1870) ; contributed reports to the Geological Survey of Ohio (lS71), and numerous scientific papers to various 'journals, but his most notable work was the '' Microchemistry of Poisons " (New York, 1867). Dr. Wormley was a member of the American Philosophical Society and of other scientific societies. He was elected a Fellow of the Chemical Society.ia 1885. F. B. P.
