specific gravity of the sample at 0° C., referred to distilled water at 
4°C, 
V,1,.».—This is the specific volume of the sample in situ, that is, 
corrected for temperature and pressure, multiplied by 105. 
In the general tables, where observations were lacking or had been 
discarded, the values have been substituted by interpolating upon 
graphs drawn from the available observations. These interpolated 
or extrapolated values have been indicated by the symbol *.
