1895. OBITUARY. 217 



JOSEPH GRANVILLE NORWOOD. 

 Born December 20, 1807. Died May 6, 1895. 



ONE of the last of the older American school of geologists and 

 palaeontologists has passed away in the person of Mr. J. G. 

 Norwood. He was born in Woodford County, Kentucky, educated 

 in local schools, and entered a printing office, shortly after publishing 

 a newspaper, a medical journal, and other matters. About 1832 he 

 left business for the pursuit of medicine, and quickly gaining his 

 diploma, secured a large general practice by the end of 1835. His 

 medical career continued till 1847, when he was urged to enter the 

 U.S. Geological Survey. From 1 847-1 851 he was assistant geologist 

 with David Dale Owen on the survey of Wisconsin, Iowa, and 

 Minnesota; from 1851-1858, State Geologist of Illinois; while from 

 1858-1860, assistant geologist of Missouri. From 1860-1880 he was 

 Professor in the University of the State of Missouri, holding the 

 chairs of Geology and Chemistry, and in 1871 he held the office of 

 State Geologist of Missouri for a few months, till a person was 

 definitely appointed. 



His chief works are " Researches among the Protozoic and 

 Carboniferous Rocks of Central Kentucky," which he published in 

 conjunction with D. D. Owen in 1847 ; " Geological Report of a 

 Survey of a Portion of Wisconsin and Minnesota," and two "Reports 

 of Progress " while State Geologist of Illinois. Dr. Norwood died at 

 Columbia, Missouri, and we are indebted to an article, with a portrait, 

 in the American Geologist for the above particulars of his life. 



FREDERICK KITTON. 

 Born 1826. Died July 22, 1895. 



ALL students of Diatomaceae will learn with regret of the death of 

 Mr. Kitton, who was, we believe, born at Cambridge. He 

 settled in Norwich about forty years ago as a retail trader, but his 

 shop became a rendezvous for men of scientific interests, similar 

 to that of John Morris and the London Clay Club. Kitton worked 

 hard at his favourite subject, and made numerous discoveries, many 

 of which were named after him. He was a frequent contributor to 

 the Microscopical journal and the Quarterly Jounial of Microscopical 

 Science, and his more recent labour is well-known to our readers as a 

 " Challenger " Report, which he produced in company with Count 

 Castracane. Apart from his science, Kitton had acquired a mastery 

 over Anglo-Saxon, and in 1883 he prepared a catalogue of the 

 Library of the City of Norwich. His eldest son, Mr. F. G. Kitton, 

 is known as the successful authority on the life and portraits of 

 Charles Dickens.
