NOTES ON THE FOREGOING TABLES. 
No. 3. Assumed azimuth S. 76° 46^' E. 
No. 5. The observer says that the meteor “passed between the Guards (j3 and y) of Ursa Minor.” 
The altitude of ¡3 at the time was 53° 13' 55", and its azimuth N. 15° 42' 32" W. The altitude of 
y was 56° 49' 1", and its azimuth N. 15° 57' 45" W. The meteor, aecording to calculation, passed 
42' 8" above the former, and 2° 49' 28" below the latter; being in a direct line between the two 
at about the azimuth given in the text. 
No. 6. Time by observation 9 h 30“. 
No. 7. Time by observation 9 h 45“. 
No. 8. At the altitude of a Lyrse (77° 29' 46") the calculated azimuth of the meteor’s centre is 
S. 76° 53' E., which gives for its distance from that star about 3^'; so that if the apparent semi 
diameter of the meteor exceeded 3^' it occulted the star. 
No. 9. At the observed altitude (77° 2') the calculated azimuth is S. 78° 39' 9" E., which gives 
14' 39" E. as the angular distance between the observed and calculated positions of the meteor. 
No. 10. Assumed azimuth, due east. 
No. 12. Time by observation 9 h 44“. 
No. 18. The meteor was observed to pass “very nearly in the line of the two lowest bright stars 
of Cassiopeia” (6 and e), “if anything different, perhaps a little below them.” The geocentric altitude 
of t at the time was 22° 44' 51." 
No. 19. Assumed azimuth N. 30° E. 
No. 20. Assumed azimuth S. 31° W. 
No. 21. See No. 18. Geocentric altitude of 8 Cassiopeia? 23° 0' 59." 
No. 24. The meteor was observed to pass near Areturus, “probably a trifle below.” Geocentric 
altitude of Areturus 39° 18' 15". 
No. 25. Passed “through the constellation Scorpio, probably a little below Antares.” Geocentric 
altitude of Antares 18° 34' 24". 
No. 26. “Passed just south of the zenith.” 
No. 27. Passed “through the constellation Bootes, a little south of Areturus,” whose altitude was 
39° 13' 16", and azimuth S. 82° 36' W. Hence, at the point of nearest approach, the distance 
between the meteor and the star was 6° 47.' 
No. 30. Passed “near the zenith, if anything a little north.” 
No. 34. Passed “about 2° or 3° below Antares,” whose altitude was 14° 28' 49"—say 14° 29'— 
from which deduct 2^°, and we have the results given in the text. 
No. 44. In making the calculations for this observation the latitude and longitude of Alexandria 
were used, the exact geographical position of the observer not being known. 
No. 59. The azimuth, when the altitude was a maximum, was about N. 15° E. 
No. 64. Time by observation 9 h 40“ to 9 h 45“. 
No. 66. Time by observation “about 9 h 50“.” 
No. 68. Time by observation “about half-past nine.” Another observer says the meteor dis 
appeared in the east at 9 h 35“. 
No. 73. The meteor “burst into view in the constellation Ursa Major below the dipper.” Geo 
centric altitude of ¡3 Ursse Majoris, the lowest star of the “dipper,” 31° 31' 49". 
No. 76(a). Time by observation 9 h 20“. 
No. 79. Assumed azimuth for maximum altitude S. 20° W. 
No. 84. Assumed azimuth due east. In order to satisfy the observation of the altitude, the 
azimuth must be a little south of east. 
No. 92. “Or perhaps a little less.” 
No. 93. The altitude at this azimuth was somewhat conjectural on the part of the observer, as he 
did not see the meteor till it was some 10° further east. 
No. 96. This azimuth is assumed from the statement of the observer that the meteor was “at right 
angles to his position.” 
No. 101. Assumed azimuth for maximum altitude. ' 
No. 118. Time by observation 9 h 30“.
