List oF CORRELATED ‘‘ ALBATROSS’’ DREDGING AND HYDROGRAPHIC STATIONS 
OF THE YEARS 1912 anp 1913 
For the purpose of rendering the hydrographic data obtained at hydrographic 
stations available for use in connection with the dredging stations, at which no 
such observations were made, this table correlating the two was drawn up at my 
suggestion by Mr. R. A. Coleman, clerk on the ‘‘ Albatross.’’ 
Following the various dredging stations, the hydrographic stations most nearly 
related to them in point of time and position are given. These in turn are fol- 
lowed by the primary hydrographic station of the group to which each belongs 
(see Appendix II B, p. 340), together with their annual mean and the range of 
both temperature and salinity. These figures are, in a degree, applicable to the 
dredging stations with which they approximately correspond. 
The actual observations for any particular hydrographic station may be 
ascertained by reference to Appendix II B (p. 342). 
As to the methéd and procedure pursued in obtaining these data, the reader 
is referred: to the Report on the Physical Conditions in San Francisco Bay (Sum- 
ner, 1914),
