566 Obituary. 



Besides his work on the New York Survey, Prof. Whitfield 

 was engaged in work for the Ohio, Wisconsin, New Jersey and 

 Black Hill Surveys, while papers furnished to journals of science, 

 and the series of special studies published in the Bulletin of the 

 American Museum of Natural History, complete his life of scien- 

 tific activity. 



Among contributions to science which merit the distinction of 

 being classed as discoveries were his detection of the muscular 

 impressions in " true Lingula " in the Trenton limestone, his 

 observations on the internal appendages of Atrypa, his reference 

 of the fossil forms Dictyophyton and Uphantcenia to sponges, 

 his description of a fossil scorpion from the Silurian rocks of 

 America, his notice of new forms of marine Algas in the Tren- 

 ton limestone, the demonstration of Balanus in the Marcellus 

 Shale, his papers on fossil teredo-like forms (^Xylophomya), and 

 the proof of three genera in a single individual of Heteroceras. 

 The long series of papers on systematic paleontology, in which 

 many new genera and species occur, with numerous observations 

 in morphology and correlation, identify his name with American 

 Paleontology. l. p. g. 



Sir William Huggins, the veteran English astronomer, died 

 in London on May 12, at the age of eighty-six years. He was 

 one of the first to use the spectroscope in the study of the heav- 

 enly bodies, and the importance of his researches into the consti- 

 tution of the comets, the stars and nebulse can hardly be over- 

 estimated. 



Professor Knttt Johan Angstrom, the eminent Swedish 

 physicist, died on March 4, in the fifty-fourth year of his age. 

 He was the son of Anders Johan Angstrom, the pioneer worker 

 in exact quantitative work on the solar spectrum, and his labors 

 were devoted to the same field of solar physics ; his most impor- 

 tant investigations had to do with absorption phenomena, partic- 

 ularly in the infra-red, and with the measurement of solar radi- 

 ation. 



Professor Julien Fraipont of the University of Liege, 

 Belgium, died March 22, 1910, at the age of 53 years. At the 

 time of his decease he was rector of the University and professor 

 af animal geography and paleontology. Author of many papers 

 on zoology, paleontology and anthropology and a member of 

 manjr learned societies, including the Royal Academy of Belgium, 

 Dr. Fraipont was perhaps best known for his work (issued in 

 1887 jointly with Professor Max Lohest) on the fossil race of 

 Spy, entitled : La race humaine de Neanderthal ou de Canstadt 

 en Belgique. Recherches ethnographiques sur des ossements 

 humains decouverts dans des depots quaternaires d'une grotte a 

 Spy et determination de leur age geologique. 



Dr. H. Landolt, Professor of Chemistry at the University of 

 Berlin, died on March 14, at the age of seventy-eight years. 



Dr. E. Philippi, Professor of Geology at Jena, and geologist to 

 the German Antarctic Expedition of 1901-03, died in March. 



Dr. Richard Abegg, Professor of Chemistry at Breslau, died 

 on April 3, in his forty-second year.
