KNOWLEDGE. 



191 



On the 15th an occultation reappearance of the first 

 satellite at 3h. 41m. a.m. On the 20th a transit egress 

 of the shadow of the second satellite at 2h. 56m. 

 A.M. On the 30th a transit egress of the shadow of the 

 first satellite at 4h. im. a.m. While visible, .Jupiter 

 describes a short direct path on the confines of Gemini 

 and Cancer. 



Saturn is still visible, but must be looked for as soon 

 after sunset as possible. On the 1st he sets at lOh. 33m. 

 P.M., or about two hours and three-quarters after the Sun, 

 with a southern declination of 9° 39', and an apparent 

 equatorial diameter of 16J ' (the major axis of the ring- 

 system being 38" in diameter, and the minor Hi"). On 

 the 19th he sets at 9h. 25m. a.m., or about two and a 

 quarter hours after the Sun, with a southern decimation of 

 10" 5', and an apparent equatorial diameter of 10;^" (the 

 major axis of the ring-system being 3C|" in diameter, 

 and the minor lOJ"). After this he gets too near the 

 Sun to be conveniently observed. While visible, he 

 describes a short direct path in Virgo, not far from 

 X Virginis. 



Uranus has practically left us for the season, and in the 

 case of Neptune we defer an ephemeris till September. 



This month is one of the most favourable ones in which 

 to observe shooting stars. The most noted shower is that 

 of the Perseids, with a radiant point at the maximum 

 display on August 10th, in R.A. llh. 52m. — 50^. Obser- 

 vations of this region with an opera glass will no doubt 

 show stationary meteors, or meteors which shift their 

 positions very slowly. Their places, and the direction of 

 their shift, should be noted for the purposes of determining 

 whether the radiant is a geometrical point, or a circle, or 

 an elliptic area, as suggested with regard to the November 

 meteors {Monthly Notices of the Roynl. Astronomical Soeieti/, 

 Vol. XLVII., pp. GG-73). The radiant point souths at 

 5h. 87m. A.M. 



The Moon is full at Ih. 51m. p.m. on the r,th ; enters 

 her last quarter at 5h. 19m. p.m. on the 13th ; is new at 

 Oh. 5iim. P.M. on the 20th ; and enters her first quarter at 

 5h. 43m. A.M. on the 27th. She is in apogee at 7h. p.m. 

 on the 7th (distance from the earth 252,320 miles), and in 

 perigee at 9h. p.m. on the 20th (distance from the earth 

 222,100 miles). At 2h. 51m. a.m. on the 5th the Gth magni- 

 tude star 17 Capricorui will make a near approach to the 

 lower limb at an angle of 331°. At Oh. 25m. a.m. on the 7th 

 the Gth magnitude star 42 Aquarii will disappear at an angle 

 of 73°, and reappear at Ih. 41m. a.m. at an angle of 214°. 

 At Ih. 44m. A.M. on the 8th the Gth magnitude star 

 81 Aquarii will disappear at an angle of G0°, and reappear 

 at 3h. 2m. a.m. at an angle of 222°; and at 3h. 17m. a.m. 

 the Gth magnitude star 82 Aquarii will disappear at an 

 angle of 10 , and reappear at 4h. 14m. a.m. at an angle of 

 274°. At 9h. 11m. p.m. on the 12th the Gi magnitude 

 star B.A.C. 782 will disappear at an angle of 52 (the star 

 being below the horizon at the time), and reappear at 

 lOh. Im. P.M. at an angle of 261°. At Ih. 44m. a.m. on 

 the 13th the 5j magnitude star jj. Arietis will disappear at 

 an angle of 22°, and reappear at 2h. 38m. a.m at an angle 

 of 278- ; and at lOh. 51m. p.m. the Gi magnitude star 

 GG Arietis will make a near approach to the lunar limb at 

 an angle of 159°. At 3h. 3m. a.m. on the IGth the 6^ 

 magnitude star B.A.C. 1746 will disappear at an angle of 

 15G°, and reappear at 3h. 17m. a.m. at an angle of 134°. 

 At 9h. 12m. p.m. on the 27th the 6,^ magnitude star 

 B.A.C. 174G will disappear at an angle of 85°, and reappear 

 (below the horizon) at an angle of 279°. At Gh. 23m. p.m. 

 on the 30th the Gth magnitude star B.A.C. GGGG will 

 disappear (in bright sunlight) at an angle of 50°, and 

 reappear at 7h. 35m. p.m. at an angle of 289°.
