Column 3 (t) contains the observed temperatures. 
Column 4 (s) contains the determined salinity. 
Column 5 (d;) contains the density as found directly from the tem- 
perature and the salinity. 
(Contraction adopted, see p. 2.) 
Column 6 (Table III) is a form of inversion table combined with 
other corrections (see p. 18). 
Column 7 (Table IV) contains the combined corrections with due 
regard to signs for the three factors, pressure with depth, with tem- 
perature, and with salinity (see p. 19). 
Column 8, contains the values of (1—v) 10 *, where v represents the 
specific volumes i in situ. 
Column 9, contains the mean values between the successive depths 
of observation as they appear in column 8. 
Column 10, contains the product of the values as contained in col- 
umn 9 and the difference of pressure in decibars as shown by column 1. 
Column 11 (22) contains the results obtained by adding progres- 
sively the successive ciphers as contained in column 10. Values from 
columns 6 to 11, inclusive, are negative throughout. 
Column 12 (EK) contains the calculation of the dynamic depths of 
the observed isobaric surfaces. 
umn 2 with those in column 11. 
Column 13 (K—E;,) 10° contains the anomaly of the dynamic depth 
of observation—i. e., it represents the difference in dynamic depth 
between the isobaric surface actually observed and the position of the 
same isobaric surface in a sea of 0.0° C. and 35 per mille salinity. 
Found by combining values in col- 
Column 14 (V) 10° contains the specific volume in situ, or one 
minus the value as contained in column 8 multiplied by 10°. 
Column 15 (V—Vj,) 10° contains the anomaly of specific volume in 
situ, or, in other words, the difference in specific volume in situ as 
found from that at a similar depth in a sea of zero degrees Centrigrade 
and 35 per mille salinity. The values for the dynamic depth (D,) and 
the specific volume in situ, (V,), as found in an ocean of zero degrees 
Centigrade and 35 per millesalinity, are given in the following table, 
Table V. The selected depths recorded therein are the same as those 
previously carried in Table IV.
