NOTES AND QUERIES, 
The late Dr. Gwyn Jeffreys, F.R.S.— It is with great regret 
that we have to announce the sudden death from apoplexy, on January 
24th, of Dr. John Gwyn Jeffreys, F.R.S., the well-known conchologist, 
who had only a few days previously attained his 76th year. On the 
evening of January 20th he read a paper before the Zoological Society, 
when he appeared in his usual health and spirits, and on the evening 
before his death was present at the Royal Institution to hear a lecture by 
his son in law, Professor Moseley. His unexpected demise will evoke a 
very wide-spread feeling of regret not only amongst a large number of 
private friends, but in a wide circle of scientists both at home and abroad 
to whom he has long been well known through his publications. Dr. 
Jeffreys was born at Swansea in 1809, and for some years, prior to his 
being called to the Bar at Lincoln’s Inn, practised as a solicitor in 
that town. His tastes, however, were rather scientific than legal. At 
nineteen he wrote “A synopsis of the Pulmonobranchous Mollusca of 
Great Britain,” and in the following year was elected a Fellow of the 
Linnean Society. He became a Fellow of the Royal Society in 1840. 
In 1869, 1870, 1871, and 1875, he either conducted or took part in 
exploring voyages in the North Atlantic and on the north-eastern coast of 
the United States. In 1880 he joined the French Sounding and 
Dredging Expedition in the Bay of Biscay. Dr. Jeffreys wrote over a 
hundred papers on scientific subjects; but he is probably best known 
by his principal work, “ British Conchology,” in five volumes. An 
assiduous attendant of the meetings of the British Association since 1836, 
he was the local treasurer at Swansea in 1848, president of the Biological 
section in 1877, and one of the vice-presidents of the last meeting at 
Swansea. 
BIRDS. 
Bird-life in Wanstead Park, Essex.— Wanstead Park, which has been 
thrown open to the public within the last few years through the action of 
the Corporation of London, is remarkable, considering its proximity to the 
metropolis, for the variety of birds that frequent its woods and waters; for 
the great city with its suburbs extends in an unbroken stretch of houses to 
within a quarter of a mile of the park-gates. The Herons, however, 
continue to arrive in early spring in undiminished numbers of from forty 
to fifty, and nest in the tall trees on an island surrounded by the broad 
ornamental waters. These trees also contain the largest rookery in the 
neighbourhood, and afford nesting-places for numbers of Jackdaws, Wood 
Pigeons, and a few Carrion Crows and Turtle Doves. Among the under. 
growth Moorhens abound, notwithstanding that a Fox has for a length of
