planets. Venus is only 6' north, and so will be in 

 the same telescopic field. When in conjunction 

 with Neptune at 9 p.m. on 2Sth she will be un- 

 fortunately below the horizon. 



Mars sets at 10.32 p.m. on 1st and 9.5 on 31st. 

 Mars is in conjunction with, 8' south of, Jupiter at 

 3 p.m. on 25th. 



Jupiter sets at 10.50 p.m. on 1st and at 9.1 p.m. 

 on 31st, so, like Mars, is fast passing from the 

 observer's ken. 



Saturn sets at 1.30 a.m. on 1st and at 11.26 p.m. 

 on 31st, being near the meridian at the beginning 

 of the month, when he first peeps through the 

 twilight. 



Uranus is a little to south of Saturn, and 

 Neptune is too near the sun for observation. 



Meteors may be looked for July nth, 20th, 21st, 

 and especially 25th to 30th.

The Central Bureau for Astronomical Telegrams 

 has the address " Astronomische Centralstelle, 

 Kiel," Professor H. Kreutz having now taken the 

 work in hand. 



The Next Great Solar Eclipse. — Professor 

 Naegamvala, on May 26th, gave an interesting 

 account, to the British Astronomical Association, 

 of the preparations being made in India for the 

 observation of this phenomenon. 



The Magnetic Observatory at Greenwich will 

 shortly be removed from within the boundaries 

 of the Royal Observatory to another part of 

 Greenwich Park, where a site has been selected. 

 This removal has become necessary owing to the 

 disturbance to the instruments caused by the 

 amount of iron in the New Physical Observatory 

 and also the great reservoir of the Kent Water- 

 works, south of the Observatory. 



The Yerkes Telescope is at last in working 

 order, and it is to be hoped that, in the hands of 

 Professor Barnard and Burnham, it will prove even 

 more efficient than the great Lick instrument. 



The Lick and Greenwich Equatoreals. — 

 According to the " English Mechanic," the ex- 

 cellence of the object-glasses of these two instru- 

 ments is such that they are found in practice to 

 separate double stars closer than theory assigns as 

 the limit of their dividing power. This speaks 

 volumes for the instrument makers. We may add 

 that the Greenwich 28-inch should by theory just 

 divide- stars 0-163" apart, whilst 0-127" would be 

 the limit of tin: ;" im h I. irk Tin: similar limit of 

 the .|i'5-inch Yerkes glass should be o-no".
