The Sex. — Small spots and groups may some- 

 times be seen. 



Mercury is an evening star all the month. 

 Teaching its greatest elongation, 23°46' east, at 

 A a.m. on October 30th, setting rather more than 

 an hour and a half after the sun at the end of the 

 month. Its path takes it from a little north of 



Spica Virginis at the beginning of the month, to 

 closely south of 5 Scorpii at the end. 



Venus is a morning star all the month. Its 

 path starts from a point about <j° west of Piegulus. 

 being closely south of that star on October 7th. 

 and on 31st passes very near to £ Virginis. It 

 is - at 1.45 a.m. at the beginning of the month 

 and rather over an hour latt-r at the end of 

 October. 



Maes rises at 11.44 p.m. on October 1st. and 

 about 25 minutes earlier at the end of the month. 

 Its path lies almost wholly through the constella- 

 tion Cancer, about the 24th inst. entering a very 

 barren portion of Leo. 



Jupiter is an evening star, but too near the 

 sun for satisfactory observation. It sets at 7.50 at 

 the beg innin g of the month, and at 6.10 at the 

 end. Jupiter is in conjunction with Uranus at 

 10 p.m. on the 19th, passing 25' to the north. 



SATURN set; &t 9.14 p.m. on the 1st. and 7.24 on 

 the 31st, so must be looked for as soon as the dusk 

 will permit. 



Up. a x us is now out of reach of our vision. 



Neptune is still on the western borders of 

 Gemini, close to Orion, and Taurus. It rises about 

 9.12 p.m. at the beginning of the month and two 

 hours later at the end. 



The Solar Eclipse. — Altogether the finest 

 photographs are said to have been taken by Mr. 

 Charles Burckhalter, with a 4-inch lens of fifteen 

 feet focus. A novel arrangement was some time 

 since invented by him by which it was possible to 

 give different times of exposure to different parts 

 of the same photograph. A plate exposed for eight 

 seconds received : —

Exposure at 



distance from the sun's limb. The result is that 

 every part of the sun's surroundings, from the 

 prominences to the outer corona, are shown in 

 beautiful detail. . Mr. Burckhalter is the director 

 of the Chabot Observatory, in California, and his 

 eclipse expedition was made possible by the muni- 

 ficence of Mr. John Dolbeer, of San Francisco. 



Daylight Meteor. — Another of these remark- 

 able objects was seen on Sunday, September 2nd. 

 at 6 h. 52 m., p.m.. just before sunset, at places so 

 far separated as Edinburgh and Wiltshire. 



The Occultatiox of Saturn on September 3rd 

 seems to have been well seen by some observers, 

 who were struck by the great difference in the 

 brightness of the planet and of the moon. From 

 one station the moon and planet presented the 

 appearance seen when objects lying at the bottom 

 of a rapidly rushing stream are being examined. 



Professor Keeler, the director of the Lick 

 Observatory, was, we are sorry to hear, snatched 

 away by apoplexy on August 12th, at the early 

 age of forty-three. Previously to succeeding Prof. 

 Holden, in 1898, he had attracted wide attention 

 as director of the Allegheny Observatory. Some of 

 our readers will possibly remember that on p. 100 

 of our third volume we noted the late professors 

 demonstration at that observatory of the character 

 of Saturn's rings, photographically showing, by the 

 displacement of the lines of the spectrum, that 

 the inner portions of the ring were revolving 

 faster than the outer sections. The plates had an 

 exposure of two hours. This great work was 

 accomplished in 1895.
