210 AMONG THE FYLDE FLOWERS. 



27 degrees eastward, and rnay possibly be seen about that time as 

 a morning star. 



Venus is very conspicuous as an evening star. Seen through 

 a telescope the form is gibbous till September 24th, the time of its 

 greatest elongation from the Sun ; after that it takes the crescent 

 form, gradually diminishing in width but increasing in diameter as 

 it approaches the Sun. 



Mars is visible throughout the evening, low in the south and 

 south-west. It will be in conjunction wath Antares, the bright red 

 star in Scorpio, at a distance of about a degree and a half, on 

 August 24. The planet will be northward of the star. A 

 comparison of these two objects in such close proximity will be 

 interesting even with the naked eye, but much more so with the 

 telescope. 



Jupiter will be in opposition to the Sun on July 30, and, of 

 course, crosses the meridian about midnight. It is very conspicu- 

 ous, though rather low — the meridian altitude at Greenwich is 

 only 19 degrees. 



Saturfi is approaching the Sun. It will be visible as an 

 evening star till the end of July ; after that it will soon be lost in 

 the twilight. On August 3.0 it will be in conjunction wath the 

 Sun. 



Uranus is an evening star. 



Neptune is a morning star, not far from Albeharan. 



The Sun crosses the Equator southward on Sep. 23rd at 2 in 

 the morning, and the Autumn Quarter commences.
