The Central Bureau suffered a sad loss through the death, on 27 July 1960, of its director Miss Julie Vinter Hansen who since 1947 had conducted its work very efficiently and with never failing interest. In order to maintain the activities of the Bureau until a permanent arrangement could be made, the supervision was temporarily entrusted to the writer who for several years has participated in its work. In this capacity I have prepared the following report, covering the period from 20 October 1957 to 31 December i960.

The work of the Bureau since 1957 has proceeded along the usual lines. The number of subscribers to telegrams and circulars, and to circulars only, has continued to rise, namely from 68 to 73 and from 117 to 158 respectively. Pleasing as is this rise, it calls, however, for a correspondingly greater amount of clerical work at the Bureau, and it would not have been possible to keep the subscription fees fairly low if we were not the recipients of subsidies from the International Astronomical Union and the Danish Rask-Orsted Foundation.

1. Statutes and By-laws. The revised Statutes and By-laws, as adopted, are printed on pages 477 in Part 6.

2. Structure of Commissions. A revised structure was adopted for Commissions.

3. Admission of Countries. The action of the Executive Committee in admitting Taiwan as an Adhering Country was confirmed. It was announced that the Executive Committee had also admitted: Brazil, North Korea, and Turkey.

4. The International Latitude Service. The resolution submitted by the International Union of Geodesy and Geophysics was adopted. It was noted that the Executive Committee had accepted the offer from the Science Council of Japan to set up the Central Bureau at Mizusawa under the directorship of Dr. T. Hattori.

5. The Unit of Contribution. It was agreed to increase the unit of contribution for the years 1962, 1963 and 1964 from 500 to 600 gold francs.

Parmi les résolutions et recommandations adoptées par les Commissions et Sous-Commissions, seules sont reproduites ici celles qui présentent un vaste intérêt et s’adressent à une large audience; les autres peuvent être trouvées dans les Comptes-Rendus de réunions, auxquels nous renvoyons. Là où ils sont donnés, les numéros des résolutions sont ceux utilisés dans les Comptes- Rendus.

2. La valeur provisoire du temps des éphémérides, obtenue en comparant la longitude moyenne de la Lune résultant d’observations rapportées à l’équinoxe du FK 4, avec les positions données par 1’Improved Lunar Ephemeris est appelée T.E.O. La différence T.E.O. — T.u.2 est appelée Δ T0.

Of the Resolutions and Recommendations adopted by Commissions and Sub-Commissions only those of wide interest and appeal are repeated here; the others may be found in the Reports of Meetings to which reference is made. The numbers of the Resolutions, where given, are those used in the Reports.

2. The provisional value of ephemeris time that is obtained by comparing the Moon’s mean longitude, given by observations, referred to the equinox of FK 4, with the positions tabulated in the Improved Lunar Ephemeris is denoted by E.T.O. The difference E.T.O. U.T.2 is denoted by Δ T0.
