welfare and health of his officers and men, and in all his 
work he certainly was assisted by an exceptionally 
diligent and accomplished staff. 
Referring to the uninterrupted observations that were 
taken during the course of the expedition he himself said 
"they will elucidate several points of importance and 
interest in science, while they present others for eluci- 
dation and afford a basis of comparison, should a sound 
mode of prosecuting inquiry be adopted." 
Ross's geographical discoveries were of the utmost 
importance and interest. They threw a completely new 
light on the economy of the southern continent, and 
pointed the way to future discoveries in the far south 1 . 
At the request of Sir James Ross Admiral Percy, 
Commander in Chief on the Cape Station, chartered a 
merchant vessel called the Pagoda with the object of 
taking a series of magnetic observations in the direction 
of Enderby Land. The command was given to Mr Moore, 
who had served in the Terror, He was accompanied by 
Captain Henry Clerk of the Royal Artillery, a scientific 
officer, son of Sir George Clerk, Bart., M.P., of Penicuick, 
and by Dr Dickson, Assistant-Surgeon of the Winchester, 
flag-ship at the Cape. The duty was satisfactorily per- 
formed during 1844-45, and an account of the voyage was 
afterwards written by Dr Dickson in the United Service 
Magazine for June and July 1850.
