future which will separate the northern spur from the rest of the 
island. 
During our stay off the island, several casts of the lead, over 
an uneven rocky ground, were obtained from the ship in 7 to 8 
fathoms, with the extremes of Rona S. 38° W. and N. 54° W. 
(mag.). 
On leaving Rona we proceeded to the cold area of the Faroe 
Channel. At 5 a.m., on the 17th August, we sounded in 540 
fathoms, and put the trawl over. 
At 10 a.m. the trawl was hauled in and contained a splendid lot 
of animals, fishes, cephalopods, starfishes, Crustacea, sponges, pycno- 
gonids, molluscs, &c. 
A tow-net attached to the trawl contained some ooze. A serial 
temperature sounding was afterwards obtained at every 50 fathoms 
to the bottom. 
For the next two days the ship was engaged in running lines of 
soundings between Rona Island, the Nun Rock, and Cape Wrath, 
and left Stornoway on Friday the 20th of August for the south. 
We were unfortunate in having bad weather during all these 
cruises. This circumstance, together with the fact that the “ Knight 
Errant ” could not carry a large supply of coal, prevented our doing 
so much work as was originally intended. 
Some most important results were, however, obtained. 
IV. Results. 
1. Observing Stations , &c . — The following (pp. 650-51) is a list 
of the observing stations during the cruise of the “ Knight Errant,” 
with the position, depth, nature of deposit, bottom temperatures, and 
meteorological observations, with serial temperatures in the warm 
and cold areas. 
The accompanying map of the Faroe Channel shows the sound- 
ings obtained by the “ Knight Errant,” in block figures, thus (540), 
while those formerly obtained are in ordinary Roman figures. The 
“ cold ” area is coloured blue, the u warm ” area pink. 
2. Wyville Thomson Ridge . — The most important result of the 
“ Knight Errant ” investigations was the discovery of the ridge 
predicted from theoretical considerations.
