THE VOYAGE OF H.M.S. CHALLENGER. 
of the wind, as registered when under sail, differed considerably from the direction 
noted when, sail being shortened, the ship was brought head to wind to sound. For 
instance, on the 24th June, at Station 242, the direction of the wind was noted as 
south when under sail, the course of the ship being east, and the speed 9 knots per 
hour, but when brought head to wind, the direction was found to be S.S.W. to S.W. 
by S. The following table shows the results of the anemometer observations whilst the 
ship was stationary : —

The deposits between Japan and the Sandwich Islands were most interesting. In 
all the greater depths there was no carbonate of lime in the deposits, but it is instruc- 
tive to notice that at two Stations where the depth was less than the average, viz., 
2300 and 2050 fathoms, there was respectively 17 and 56 per cent, of carbonate of
