34 Mr. Christie on the effects of temperature on 
3. Table of the increments in the Azimuths of the Points of Equi- 
librium corresponding to a decrement of\°in the Temperature of 
the Magnets j with their several orders of differences, calculated at 
intervals o/^30' in the Azimuths from 74° to 82°, and at intervals 
of 15' in those from 82° to 86°; the distances of the centres of the 
Magnets from the centre of the Needle being inches.
