Tue Institution of Mining Engineers has awarded 
its medal this year to Dr. J. S. Haldane, F.R.S., in 
recognition of his work on the causes of death in 
colliery explosions and other subjects connected with 
mines, 
WE notice with much regret the announcement that 
‘Captain J. W. Jenkinson, late fellow of Exeter Col- 
lege, Oxford, and University lecturer in embryology, 
was killed on June 4 in the trenches in Gallipoli. 
He was forty-three years of age. 
Ir is announced in the issue of Science for May 28 
that at its annual meeting, held on May 12, the 
American Academy of Arts and Sciences, acting upon 
the recommendation of the Rumford Committee, 
voted: ‘‘That the Rumford Premium be awarded by 
the Academy to Charles Greeley Abbott for his re- 
searches on solar radiation.” 
A joint meeting of the Aristotelian Society, the

meeting of the Mind Association will be held. Prof. 
G. F. Stout will contribute a paper on Mr. Bertrand 
Russell’s theory of judgment. On July 5 the meet- 
ing will be at 22 Albemarle Street, London, W. At 
4 p-m. the annual meeting of the Aristotelian Society 
has been arranged, and at 5 p.m. there will be a 
symposium on the import of propositions, by Miss 
Constance Jones, Dr. Bernard Bosanquet, and Dr.

WE referred in Nature of June 3 to the forthcoming 
sale of Stonehenge by auction. The property is under 
the protection of the Ancient Monuments Act, which 
ensures its preservation; and the auctioneers, Messrs. 
Knight, Frank, and Rutley, 20 Hanover Square, W., 
announce that Sir Cosmo Antrobus, who is only tenant 
for life, proposes, if his powers permit him to do so, 
to impose conditions providing for the public having 
access thereto for all time. It is hoped, however, 
that Stonehenge may be bought either by the Govern- 
ment or by a learned society, and if any reasonable 
proposal be made for its acquisition with the intention 
of preserving the monument in the public interest, 
the auctioneers are instructed to facilitate a sale by 
private treaty before the auction. 
In Nature of May 20 we announced the death of 
Prof. P. Zeeman, since 1902 professor of geometry 
and theoretical mechanics in the University of Leyden. 
Prof. Zeeman was born at Hoorn (Holland) in 1850, 
studied in Leyden, and in 1882 became professor of 
mathematics at the Polytechnic School (now Technical 
High School), Delft, where he remained until his 
appointment at Leyden. He was the author of many 
contributions to geometry, and an admirable teacher 
and examiner, who won the affection of all his pupils 
and colleagues. Prof. Zeeman, of Leyden, has been 
confused with Prof. P. Zeeman, of Amsterdam. It 
may, therefore, be worth mention here that the pro- 
fessor of physics of Amsterdam is much younger than 
his late Leyden colleague, being born in 1865, and no

near relative of the latter. Prof. Zeeman of Amster- 
dam also studied at Leyden, and there discovered in 
1896 the magnetic separation of the spectral lines which 
bears his name. In 1897 he became lecturer, in 1900 
professor, at Amsterdam; and in 1908 he succeeded 
van der Waals as director of the Physical Laboratory. 
WE record with much regret the death on June 15, 
at eighty-six years of age, of Sir Nathaniel Barnaby, 
K.C.B., honorary vice-president of the Institution of 
Naval Architects, and formerly Director of Naval Con- 
struction. From an obituary notice in Wednesday’s 
Times we extract the following particulars of his 
career and work. Nathaniel Barnaby entered Sheer- 
ness Dockyard as a shipwright apprentice when four- 
teen years old, and in 1848 gained one of the scholar- 
ships thrown open to competition among his class by 
the Lords of the Admiralty. He passed through the 
Portsmouth School with distinction, and was appointed 
a draughtsman in the Royal Dockyard at Woolwich 
in 1852. He was afterwards transferred to the Con- 
structive Department of the Admiralty as a draughts- 
man; and for thirty years he remained in that depart- 
ment, rising to be its head in 1870, when Sir Edward 
Reed resigned his position of Chief Constructor. In 
1872 he was definitely appointed to the position ot 
Chief Naval Architect, a title which in 1875 was 
changed to that of Director of Naval Construction. 
In this position he continued with eminent success 
until 1885, when overwork caused a serious failure of 
health, and he decided to retire from the public ser- 
vice, being succeeded by the late Sir William White. 
After his retirement from the public service Sir N. 
Barnaby took, naturally, a less active part in ques- 
tions of naval construction than previously. He was, 
however, often seen at the meetings of the Institution 
of Naval Architects, of which he was one of the 
founders, and the Transactions of which contain a 
number of papers from his pen, from the first volume 
onwards. Sir N. Barnaby was also the writer of 
articles of a technical character for the ‘‘ Encyclopaedia 
Britannica,” and of several books on shipbuilding and 
naval development. He leaves a married daughter and 
a son, Mr. Sydney Barnaby, who holds the position of 
technical director and naval constructor with Messrs. 
Thornycroft.

on May 29 the following officers were elected :—Presi-
