R em a r q u e I. Nous possCdons maintenant deux tableaux des perturbations de 1221 par Jupiter, Ctablis pour des valeurs assez voisines des ClCments e , i, w , 51 et pour des valeurs trbs diffkrentes de n (1282'1093 et 1329'16154). Pratique- ment, quand on aura trouvC la valeur dCfinitive de n , il suffira d'interpoler les tableaux de perturbations (AN 246.339), et le prCsent tableau, pour avoir la valeur dCfinitive des pertur- bations. D'oh l'utilitk du prCsent tableau.

Remarque 11. Si la valeur de n Ctait tout h fait exacte, il y aurait lieu de calculer le coefficient de l'argument 3M"-8M; M" Ctant l'anomalie moyenne de la Terre et M l'anomalie de 1221. On a 3nf'-8n=4'17656; la planbte et la Terre revien- draient tous les 5 ans aux m&mes points de leurs orbites si n Ctait exact. La valeur de n n'est pas assez sGre pour faire le calcul rapide par la mCthode de Cauchy (Ann. de Paris 7.165, 296; 8.135-136).

Occultations of stars by the Moon observed during the years 1928-32. By Axel' V. mielsen.

The observations of occultations published in the present paper were made during the five years 1928-32 with the 135 mm guiding telescope of the reflector of the Aarhus Observatory. The eye-and-ear method was employed and tenths of a second were estimated.
The reductions were carried out by Innes' method (AJ 835). Following Prof. Brown's suggestions (AJ 876, 922) the positions of the Moon derived from the Nautical Almanac were corrected as follows:
Year Correction 1928 + o . z r z A X 1929-32 + 0.182 AX
D D . R D
where AX is the variation of the longitude of the Moon per minute.
The observations and the results of the reductions are given in Table I. With regard to some of the notations in this Table, see Imzes' paper quoted above. Table 2 gives parti- culars of adopted positions for stars not included in the Nautical Almanac. I am greatly indebted to Dr. V . Guth (Prague) for sending me new positions for two of these stars.
The observations had previously ' been forwarded to Prof. Brown, and have been used by him in his yearly dis- cussions of observations of occultations.
