 the 19th example, by combining the azimuth and altitude 

 at Wenham with the azimuth 170° 30' at Kutlaud ; from 

 ivhicli^t' appears probable, that the azinnuth of the ineieor 

 at Tlutland, ut the time of its disappearance, must have 

 been about 170° 30', and the corresponding calcvfatfd alti- 

 t4tti<at at' that '|)lace 5" 45'* ; but, by Mr. Page's observa- 

 tions, the azimuth of the meteor at the time of its disap- 

 pearance was 17-2'* or 173°, being about 2° greater than by 

 the pi'ebedihg calculations ; and it seems reasonable to 

 itiake the patiie allowance on the first azimuth, observed at 

 Rutland. This correction being made, the azimuths be- 

 coVne 168'' 30' and I70" 30', and the altiudes 18' 27' and 

 5*^5', corresponding respectively to the first and last obser- 

 vations at Rutland. The azimuth correponding to any 

 intermediate altitude may be found sufficieutly near by 

 supjjosing the variations of altitude and azimuth to be pro-

 pohdirig'to the altitudes of 6° 30' and 7° 30't would be re- 

 spectively 170" 23' and 170° 14'; which are rather less than 

 the azimuths made use of in examples^ li and 7« The 

 changes to be made in the results of these examples, for 

 tiiis small diflerence of azimuth, may be easily estimated 

 by comparing those examples with the 12th and 8th. In 

 this way were found theassumed values, corresponding to those 

 examples, given inthe right hand columns of Table I. By 

 tcfking the mean of the assumed values in Table I, corre^- /

 of those deduced from examples 9» 10; and]], 12; there 

 will be obtained the altitudes, latitudes, and longitudes of

* Mr. Pope states, tliat he saw the meteor till it descended below^ th*
