servator of the Hunterian Museum; and on the retirement of Pro- 
fessor Owen, he was elected to succeed him as curator, and was also, 
as above stated, named professor of histology—appointments which 
he held at the time of his death. He was elected into the Linnean 
Society on the 17th March, 1857; and died at Pangbourne, in Berk- 
shire, on the 20th August, 1861, at the early age of 46. 
Thomas Haswell Quigley, M.D., was a surgeon in the Royal Artil- 
lery. He was elected into the Society, November 20, 1821, and died 
June 14, 1861, at his residence, Mount Pleasant Square, Dublin. 
Sir James Clark Ross, F.R.S., F.RAS., F.GS., §¢., was born in 
London in the year 1800. In 1812 he was entered as a midship- 
man on board the ‘ Briseis,’ commanded by his uncle Sir John Ross, 
the well-known Arctic navigator, and whom he accompanied on his 
first voyage to the Polar Seas in 1818. Between 1819 and 1827 
he returned four times to the same regions, under the orders of Sir 
Edward Parry, by whom he was highly esteemed as a zealous and 
efficient officer. In the latter year he was raised to the rank of 
commander. 
In different voyages to the Arctic Seas, again under the com- 
mand of his uncle, between 1829 and 18383, the scientific observa- 
tions were committed principally to his charge, and he was also 
repeatedly placed at the head of expeditions sent out from the ice- 
locked ship for the exploration of the surrounding country. In the 
course of these expeditions he made the discovery of the north 
magnetic pole in 70° 7’ N. and 45° 9' E. In 1834 he attained the 
rank of captain, and in the following year commanded an expedi- 
tion in search of several whalers which had been caught in the ice in 
Baffin’s Bay. 
From 1836 to 1838 Sir James Ross was employed by the Admi- 
ralty in the determination of the points of magnetic deviation and 
declination in Great Britain and Ireland—labours which have served 
as the basis upon which were founded the isodynamic lines in 
the charts published by General Sabine. In 1839 he took the 
command of a scientific expedition sent out, at the suggestion of 
the Royal Society, to explore the Antarctic regions. Three times 
did he endeavour to break through the icy barrier which surrounds 
the Antarctic pole, but in vain, as he was unable to advance beyond 
the latitude of 78° 10’ S., a limit, however, which has not been 
since surpassed in that direction, and had not previously been 
reached. 
In this voyage, also, was discovered the great Antarctic continent 
of Victoria Land, distinguished by the existence of a volcano 3800
