geology and zoology. M c Cormick, enthusiastic, energetic, 
and tireless, had been Assistant-Surgeon in the Hecla 
with Sir Edward Parry. Afterwards he commanded a 
boat to examine the western side of Wellington Channel 
in 1852 during the Franklin search. In his old age 
Dr M c Cormick published an interesting narrative of 
his three polar voyages, and was quite indefatigable in 
helping and advising us when we were fitting out for 
the search expedition in 1850. Dr Robertson of the 
Terror was equally hard working, but not so excitable 
and sensitive. He was afterwards Surgeon of the Enter- 
prise with Sir James Ross in the first Franklin search 
expedition. 
Of the Assistant-Surgeons, Sir Joseph Hooker, though 
then a very young man, was already a skilled botanist. 
He was a most valuable member of the expedition, and 
his future eminence had some of its roots within the 
Antarctic circle. His colleague Dr Lyall of the Terror, 
a zealous botanist, was a scientific student of rare ability 
and had a distinguished career. He was afterwards 
naturalist of the Acheron, New Zealand surveying ship 
from 1847 to 1852, then surgeon of the Pembroke during 
the Russian war, and afterwards of the Plumper, surveying 
ship in the North Pacific. He was surgeon of the Assist- 
ance in the Arctic expedition of 1852-54, and made 
a valuable collection of plants in Wellington Channel. 
Dr Lyall, after a very useful career, died as a Deputy 
Inspector, on the 25th February, 1895. 
Mr Tucker, Master of theErebus, was a very capable and 
efficient officer, afterwards Staff Commander and a useful 
member of the Thames Conservancy Board. Mr Cotter 
was Master of the Terror. Henry Yule, the second 
Master of the Erebus, was a good survej^or and continued 
his service in that capacity on the Home Survey. John 
Davis, second Master of the Terror, was an officer of 
much ability, a good surveyor, and an excellent artist. 
He had previously served under Captain FitzRoy on 
board the Beagle in Magellan's Strait. He executed the 
charts and drawings for Sir James Ross, for which he 
received the special thanks of the Hydrographer. After- 
wards he was employed as a surveyor in the Fox with 
Sir Allen Young in 1862, and Naval Assistant to the
