Miss Marianne North, a distinguished English botanist, traveler, and artist, died August 30th. Her career may be said to have begun in 1869, when she started to travel with a view of illustrating the flora of some countries not then perfectly known. She visited on different excursions Teneriffe, Brazil, the West Indies, California, India, Ceylon, Borneo, Java, Japan, Australia, and the Seychelles, and brought back at various times during twelve years collections of drawings in oils and water-colors of the scenery, vegetation, and flora which she had studied in their several habitats. In 1881 she presented a series of 627 pictures to the nation, for which she erected a gallery in Kew Gardens at her own expense.

Thomas Carnelley, Professor of Chemistry in the University of Aberdeen, died August 27th, at the age of thirty-eight years. He was born in Manchester, England; had a brilliant career in Owens College; received the Dalton Chemical scholarship in 1872 for his original investigation of the vanadates of thallium; and gained it for another year, on examination; was private assistant to Prof. Roscoe, and, having studied abroad, became professor in succession at Owens College, the North Staffordshire School of Science, Firth College, Sheffield, University College, Dundee, and the University of Aberdeen. He prosecuted valuable researches in the extension and application of Mendeleef's periodic law; made chemical and bacteriological examinations of the air of dwellings, schools, etc., in Dundee and its district, which aroused interest in ventilation; and besides many contributions to English and foreign chemical journals, published a large book on certain physical constants of chemical compounds.

Signor Orazio Silvestri, a distinguished chemist and vulcanologist, recently died at Catania, Sicily, at the age of fifty-five years. He was an industrious student of the eruptions of Mount Etna, and founded the laboratory on top of the mountain at the height of upward of 13,000 feet.
