Carlsoar near Gotland, on post-Glacial depressions in Gotland, and 
on the stratigraphy of that island. For one, however, whose 
scientific activity extended over half a century, the number of 
Lindstrom’s publications is not great—scarcely one for each year, 
all told. But everything he produced was well-considered, ex- 
haustive, and as final as the then-known material permitted. 
‘Theories and systems are the fabric of a dream, but these massive 
piles of fact, accurately hewn and exquisitely put together, will last, 
as do the medieval remains of Visby, to serve future generations 
for a quarry of beautiful detail, and a monument of a master- 
builder. [F. A. B.] 
Baron Apotr Ertx Norprensxi0Lp, who was elected a Foreign 
Correspondent of our Society in 1869, and a Foreign Member in 
1880, and to whom the Murchison Medal was awarded in 1900, 
died suddenly last August, at the age of 68. Descended from a 
Swedish, family of scientific distinction, which had been settled 
for many generations in Finland, he was born at Helsingfors on 
November 18th, 1832. After receiving his scientific education at 
the University of Helsingfors and in Berlin, he settled in Sweden ; 
and, following his father’s studies in mineralogy, became Curator of 
the Mineral Collections of the Academy of Sciences at Stockholm. 
At the age of 26, Nordenskidld made his first journey to Spitsbergen, 
as geologist to an expedition under Dr. Otto Torell. Three years later 
he accompanied Torell on his second voyage, and subsequently he 
himself took charge of an expedition to Spitsbergen for the special 
purpose of measuring the arc of a meridian. For the best five- 
and-twenty years of his life, Nordenskidld was devoted to Arctic 
exploration, making successive journeys to Greenland and to 
Siberian waters, his work culminating in the memorable voyage of 
the Vega and the accomplishment of the North-east Passage. In 
all his Arctic work he lost no opportunity of geological study: at 
one time he would be busy unearthing fossil plants from Tertiary 
deposits in Greenland ; at another time he was collecting the dust 
which had accumulated on the surface of the Arctic ice, or examin- 
ing the enormous masses of metallic iron which he discovered at 
Ovifak, Glacial phenomena always attracted his attention. Inthe 
later years of his life, when his Arctic career had closed, he turned 
to the study of the early history of cartography, and this resulted 
in the publication of the ‘ Facsimile Atlas’ and his work entitled 
‘Periplus.’ Baron Nordenskiold combined, in a remarkable manner,
