Some of the zones have been published (Kazan, Christiania, Helsingfors, Lund), others are in press, and the catalogues have been begun. Three of the catalogues (Albany, Helsingfors-Gotha, and Christiania,) have just appeared. Meanwhile the zones have been extended to the southern sk\', the fol- lowing being to a greater or less extent under way: —2° to — 6^ Strasburg. —14-^ to—18^ Washington. —6 to — 10 Vienna. —18 to—23 Algiers. -10 to — 14 Cambridge (U. S. ). The positions of the 303 fundamental southern stars are furnished by observations undertaken at the Cape of Good Hope, Madison, Annapolis, Carlsruhe, Leiden, and Strasburg. Gould's southern zones extend from —23° to—80°, and it is to be hoped that before loug we shall have a catalogue embracing the whole sky, the value of which will be in no wise diminished b}" the photographic chart which is about to be begun. The observations for the Helsingfors-Gotha catalogue were made al- most entirely by Dr. Krueger with a 0"'. 15 ( inch) Reichenbach merid- ian circle. The star positions are for the epoch 1875, and besides the right ascension and declination, the precession and secular variation, and wherever possible the proper motion are given. The observations forthe Albany zone were madeby Professor Boss with a 0'". 20 ( inches) Pistor & Martin's
