 (see former report, 1915, pp. 32-37), unless followed by the letter P, which 

 indicates a pycnometer determination (see former report, pp. 28-30). Omission 

 of salinity and specific gravity entries signifies either that no water sample 

 was taken or that an error was discovered whose magnitude made the observa- 

 tion valueless. A question mark (?) indicates that a smaller error in depth, 

 temperature, or salinity is susjieeteil (see p. 216).
