•Local disturbance. 



'The swings at San Francisco, on each of the 3 days, were made on 16 equidistant headings, with both helms; as the methods of observation were more or less experi- 

 mental, only the mean results of the 3 days are given. 



'Before the swing on August 23 at San Diego, made between land stations I and III, iron bolts in foremast were replaced by brass ones. Swung at anchor; tug about 40 

 yards off the stern. 



'After additional alterations of vessel were made (see p. 131), and instruments were rearranged on observing bridge (see Fig. 1, B, p. 27). Swung at anchor; tug about 40 

 yards off the stern. 



*The compass and dip-circle results for this swing were not used. 



'December 4 and 6 the iron-fastened dinghy was inadvertently left lying across main hatch, directly under the observing bridge. 



•Deflecting magnet of sea deflector in place on bridge. 'Deflecting magnet of sea deflector removed from bridge. 



•Local disturbance. 'Intensity deviation-coeflSoienta and probable errors are expressed in units of the fourth decimal c. a. b. 



•Owing to the limited number of headings, but small weight is to be given these values. 'Vessel rolling oonsiderably. 



*Ship on even keel before the wind, except for roiling.
