526 Obituary—Edward Charlesworth, F.GS. 
they seem to consider the vernacular unsuitable even for the simplest 
forms of spicules. As an illustration of the peculiar language 
current amongst leading spongiologists the following description of 
a simple spicule is taken from one of the “Challenger” Reports 
on Sponges :—‘ Tylotoxea. The esactine of the rhabdus is tylote 
and the ecactine oxeate.” It will hardly be believed then when 
interpreted into English this sentence only means that the spicule 
is pin-shaped, having a knob or head at one end and tapering to a 
point at the other. The true interests of science are hardly likely 
to be advanced by such a pedantic employment of Greek, but it is 
a very effectual method of darkening knowledge and restricting it 
to a very select circle of Illuminati. We do not in the least wish to 
impute that Dr. Rauff or other authors use the Greek with such 
a purpose; they will probably allege that only in this way can a 
scientific nomenclature be obtained. 
In conclusion we desire to express our hearty appreciation of the 
thoroughness and accuracy of Dr. Rauff’s work and of the service 
he is rendering to paleontology; and we anticipate with much 
interest the appearance of the remaining portions of this Monograph.

CONCENTRIC LAMINATION AMONGST THE PEBBLES ON 
NORTHAM RIDGE. 
Srr,—Owing to an insufficient index I unfortunately missed Mr. 
Townshend Hall’s paper on the above subject in the ‘ Transactions 
of the Devonshire Association,” vol. iv. p. 433. Mr. Hall maintains 
that the lamination “‘has been produced by the effects of the long- 
continued hammering and pounding which the pebbles have received 
one from the other.” While regretting my oversight, 1 cannot but 
rejoice that these curious cases of lamination by pressure in the form 
of percussion have been so well attested. A. R. Hunt.

EDWARD CHARLESWORTH, F.G.S. 
Born SEPTEMBER 5TH, 1813. Diep Jury 28TH, 1893. 
TueErE has lately passed away from the geological ranks one who 
for many years was a prominent figure at the meetings of the Geo- 
logical Society and the Geologists’ Association. 
Edward Charlesworth was born at Clapham, Surrey, on the 
oth September, 1815. He was the eldest son of the Rev. John 
Charlesworth, M.A., rector of St. Mildred’s, Bread Street, London, 
and grandson of the Rev. John Charlesworth, a Fellow of Trinity 
College, Cambridge, and vicar of Ossington. 
Mr. Charlesworth’s father was much interested in geology, through 
the influence of Prof. Lambert, and at an early age he imbibed a strong 
taste for collecting fossils, which became the ruling passion of his life. 
He was educated at a private school by the Rev. W. Kitchin, 
rector of Nedging and Norton, Suffolk, and father of the present
