mined by the relative values of v, the water being forced upwards most 
pronouncedly at that vertical where the values of v are a maximum. 
Itiscustomary and of assistance in dynamic investigation of an ocean 
mass to represent the distribution of specific volume, as found by act- 
ual observations, graphically in vertical projection, the pressure in 
decibars being shown as ordinates in the graph. Figure 10 includes a 
line of signe: 201 to 206, taken from he records of { the International 
Tce Patrol, and furnishes an example of such a method of illustration.
