Abstract
PERTURBATIONS OF HALLEY'S COMET—From an investigation of the Jupiter perturbations of Halley's comet, Messrs. Cowell and Crommehin find that the perihelion passage of that comet will probably occur about a fortnight earlier than the date given by Pontécoulant, that is, in the first half of May, 1910. What is more important, they also find that Pontécoulant's perturbations were about ten times too great, and consequently the perihelion distance will be appreciably the same (0.59) as at the last return, instead of being shifted some nine million miles nearer to the earth as found by the French investigator (Monthly Notices, vol. lxvii., No. 3, January).
