During three of the periods and part of another (see p. 26) the 
Price current meter was used. 
At one complete series of the regular hydrographic stations in 
April and May, 1912, the Ekman bottom sampler was regularly em- 
ployed, while at one series in January, 1913, the ‘‘ Albatross’’ sampler 
was employed. ; 
In the ease of stations H-5219 to 5227, it is probable that ‘‘inter- 
be) 
mediate’’ and ‘‘bottom’’ records for the temperature and salinity are 
sometimes inaccurate, owing to the failure of the intermediate water 
bottle to remain clamped in position, or of the second messenger to 
become released.
