Mr. Jackson furnishes the following ephemerides.

(1) is computed for inclination = 153° 43.7'
(2) is computed for inclination = 150° 0.0'

   The inclination is not determined satisfactorily, and considerable errors may be introduced into the calculation for 1899. For this reason Dr. Jackson made two sets of calculations, copied above.
  Took list of plates given in H.C. 97 for Jupiter in 1899. Marked the approximate positions for June 27, according to above ephemerides, on A 3657. Superposed A 3654 taken the preceding day, June 26. the exposures were 120^m and 174^m for A 3654 and A 3657. A region about 25' in diameter was examined with the two plates superposed. No evidence of motion could be detected in any star, though
