path from the confines of Gemini through Cancer into 

 Leo, passing through part of Prsesepe on the 13th. 



Both Mars and Jupiter have left us for the season. 



The minor planet Pallas is in opposition to the Sun on 

 the 7th, her magnitude at the present opposition being 

 about equal to an 8j magnitude star. She transits on the 

 2nd at Oh. 41m. a.m., with a northern declination of 

 25" 16' ; on the 14th at llh. 44m. p.m., with a northern 

 declination of 25" 31' ; and on the 26th at lOh. 47m. p.m., 

 with a northern declination of 25" 1'. Her path through 

 the month is described in the constellation Hercules. She 

 is in conjunction with the 3j magnitude star S Herculis at 

 9h. 45m. P.M. on the 20th, 22^' to the north, and with the 

 65 magnitude star 62 Herculis on the 29th, 10 to the 

 north. 



Saturn is, notwithstanding his somewhat low altitude, 

 favourably placed for observation. He rises on the 1st at 

 3h. 56m. P.M., with a southern declination of 9° 28', and 

 an apparent equatorial diameter of 18|" (the major axis of 

 the ring-system being 42^" in diameter, and the minor 

 12-0"). On the 10th he rises at 3h. 27m. p.m., with a 

 southern declination of 9'^ 22', and an apparent equatorial 

 diameter of I85" (the major axis of the ring-system being 

 42" in diameter, and the minor llf "). On the 18th he 

 rises at 2h. 55m. p.m., with a southern declination of 

 9° 19', and an apparent equatorial diameter of 18" (the 

 major axis of the ring-system being 411" in diameter, 

 and the minor II5"). On the 30th he rises at 2h. 7m. 

 P.M., with a southern declination of 9° 18', and an 

 apparent equatorial diameter of 17|" (the major axis 

 of the ring-system being 40|" in diameter, and the 

 minor IIV')- Titan is at his greatest eastern elon- 

 gations at llh. A.M. on the 2nd and 10|h. a.m. on the 

 18th ; and lapetus at his greatest western elongation 

 on the 20th. During June, Saturn describes a short 

 retrograde path in Virgo, without approaching any naked- 

 eye star very closely. 



Uranus is an evening star, and but for his great 

 southern declination would be well placed for observation. 

 He rises on the 1st at 5h. 41m. p.m., with a southern 

 declination ot 16° 45', and an apparent diameter of 3-8 '. 

 On the 30th he rises at 3h. 42m. p.m., with a southern 

 declination of 16° 21'. During June he describes a short 

 retrograde path in Libra, without approaching any naked- 

 aye star. 



Neptune is in conjunction with the Sun on the 6th. 



There are no well-marked showers of shooting stars in 

 June. 



The Moon is full at llh. Om. a.m. on the 7th ; enters her 

 last quarter at llh. 28m. p.m. on the 15th ; is new at 

 9h. 51m. P.M. on the 22nd ; and enters her last quarter 

 at 2b. Im. p.m. on the 29th. She is in apogee at 3h. p.m. 

 on the 13th (distance from the earth 251,320 miles) ; and 

 in perigee at noon on the 5th (distance from the earth 

 225,260 miles). At 8h. 46m. p.m. on the 2nd the 5th 

 magnitude star \|/Virginis will make a near approach to the 

 lunar limb at an angle of 217". At lOh. 44m. p.m. on the 

 6th the Si magnitude star r Seorpii will disappear at an 

 angle of 185°, and reappear at lOh. 59m. p.m. at an angle 

 of 206°. At lOh. 44m. p.m. on the 9th the 6th magnitude 

 star B.A.C. 6666 will disappear at an angle of 03°, the 

 star rising at the time, and disappear at llh. 56m. p.m. at 

 an angle of 283°. At lOh. 47m. p.m. on the 25th the 0th 

 magnitude star 83 Cancri will make a near approach to 

 the lunar limb at an angle of 23°. At 8h. 4m. p.m. on the 

 26th the l^ magnitude star a. Leonis (Kegulus) will dis- 

 appear at an angle of 147°, the Sun being above the 

 horizon at the time, and reappear at 8h. 50m. p.m. at an 

 angle of 275°. At 8h. 8m. p.m. on the 29th the 0th 



magnitude star 28 Virginis will make a near approach to 

 the lunar limb at an angle of 34°, the Sun being above the 

 horizon at the time.
