Obituary—Edward Charlesworth, F.GS. 527 
Dean of Winchester. At an early age he was articled to an eminent 
London physician and later on entered Guy’s Hospital as a student ; 
but, having a distaste for medicine, he abandoned it and turned his 
attention to scientific subjects, especially to geology. 
When only 22 years of age he published a masterly paper “On 
the Crag-formation and its Organic Remains” (Phil. Mag. vol. vil. 
1835, pp. 81-94). He therein pointed out that the Crag of Suffolk 
was divisible into two parts, which he termed respectively the 
“ Coralline ” and the “Red Crag.” These divisions were accepted 
by Lyell, and they have now become permanently established. He 
subsequently pointed out that the Crag of Norfolk formed a newer 
division, which he named the “ Mammaliferous Crag”; but to this 
bed the term ‘“‘ Norwich Crag” is now generally applied. 
In 1835 Mr. Charlesworth was elected a Fellow of the Geological 
Society of London, and remained a Fellow up to the time of his 
death—nearly sixty years. 
In the same year (1835) he was elected an Honorary Curator of 
the Ipswich Museum, where some of his early collections of Crag 
fossils are still preserved. He read a paper “On the remains of 
Vertebrate animals found in the Tertiary beds of Norfolk and 
Suffolk ” before the Geological Section of the British Association at 
Bristol, in 1836, presided over by Prof. Dr. Buckland. In the same 
year he obtained an appointment on the staff of the British Museum. 
Jn 1837 Mr. Charlesworth was appointed an Assistant to the Museum 
of the Zoological Society of London, in Leicester Square; he also 
succeeded Loudon as Editor of the “ Magazine of Natural History,” 
which he continued to conduct until 1840. At this time he contri- 
buted several papers, on the comparative age of Tertiary deposits ; 
on Voluta Lamberti; on Terebratula variabilis; and on the teeth of 
Carcharodon megalodon from the Crag, etc. 
In 1840 he left England to take charge of a young gentleman of 
fortune and travel with him through Central America. At this time 
he occupied himself in patenting an “elevator gun,” which he be- 
lieved to be indispensable for the naturalist and explorer abroad, and 
hoped to see adopted also for the British army. Twenty years later 
an enterprising American, Mr. Pomeroy Button, of Cheapside, 
obtained for it, by advertising extensively, an ephemeral success of a 
few months and a temporary accession of capital to its inventor; but 
it was of too brief duration to lead on to fortune. 
On returning to England Edward ‘Charlesworth was, in 1844, 
appointed successor to Prof. John Phillips, as Curator to the York- 
shire Philosophical Society’s Museum in York, a post which he held 
until 1858. In 1846 he brought out the “London Geological 
Journal,” which contained most valuable contributions from the 
leading palzontologists of the day, and occasionally strong and useful 
critiques on some of their published facts and opinions. This 
publication was profusely illustrated by plates; but unfortunately 
it only extended to three numbers and ceased in 1847. 
In this Magazine he contributed a valuable paper on the occurrence 
of flint in the pulp-cavity of a tooth of Mosasaurus.
