The Sun usually has one or more groups of 

 small spots upon its disc. The earth is farthest 

 from him at 2 p.m. on the 2nd July. 



Mercury is an evening star, at the end of the 

 month setting nearly an hour later than the sun. 

 At 10 a.m., on the 27th, he is in conjunction with 

 a Leonis (Regulus), which is 0° o' S., and therefore 

 in the same telescopic field. 



Venus is a briUiant object after sunset. At the 

 beginning of the month she sets nearly two hours 

 later than the sun, and at the end of the month 

 about one hour twenty-five minutes later. 



Mars rises at 0.54 a.m. at the beginning of 

 July, and at 11.48 p.m. at the end of the month. 



Jupiter sets at 11,36 p.m. at beginning of the 

 month, and at 9.49 p.m. at the end, so should be 

 looked for early in the evening. 



Saturn and Uranus are unfortunately too low 

 in declination south for very delicate observation, 

 though otherwise fairly placed, being above the 

 horizon nearly all the evening, Saturn setting just 

 before midnight at the end of the month. 



Neptune is too close to the sun for study. 



Meteors may be specially looked for on July 

 nth, 20th, 2ist and 25th to 30th. 



Eclipse of the Moon. — A partial eclipse of the 

 moon occurs on July 3rd. The first contact of the 

 moon with the penumbra is at 6.48 p.m., and with 

 the shadow at 7.46. The last contact with the 

 shadow is at 10.49, and with the penumbra at 

 11.47. The first contact with the shadow com- 

 mences 49° from the north point of the moon's 

 limb toward the east, and the last 70° from the 

 same towards the west. As the moon does not 

 rise at Greenwich until 8.18 p.m. only the latter 

 part of the eclipse can be visible from these 

 islands. At the middle of the eclipse, 9.1 7*5, the 

 magnitude of the eclipsed portion will be 0-934. 



Annular Eclipse of the Sun. — This happens 

 on the evening of July i8th, but is invisible in 

 England, the favoured portion of the world being 

 the southern hemisphere. 



" The Second Moon of the Earth." — July 30th 

 is the day predicted for the transit of this supposed 

 body across the disc of the sun. Of course our 

 readers interested in these matters will keep a 

 sharp look out on that day, weather permitting, 

 and they will see — what they will see. 



The Lick Observatory is losing the services of 

 Professor J. M. Schaeberle, who has resigned. 



Total Solar Eclipse of 1900, May 28th, is 

 already drawing attention. Messrs. G. F. Chambers, 

 W. H. Wesley, Crommelin and Newbegin made 

 remarks about it at the meeting of the British 

 Astronomical Association on May 23rd. The line 

 of totality crosses Portugal, Spain and Algiers, 

 and so the phenomenon is within easy access of 

 observers in this country. 



The greatest proper motion known until recently 

 was that of the 7th-magnitude star, Groombridge 

 1830, on the borders of Ursa Majoris and Canes 

 Venatici, and which amounted to 7"-o of a great 

 circle per annum. Professor Kapteyn announced, 

 however, in the " Astronomische Nachrichten," 

 No. 3,466, the discovery by himself and Mr. 

 R. T. A. Innes, of a motion equal to 8''-7 of a 

 great circle, in the case of an orange yellow star 

 just below 8th magnitude, in the Cordoba Zone 

 Catalogue, in the constellation Columba. 



Mr. Herbert Sadler, the eldest son of the late 

 Prebendary Sadler, of Honiton, Devon, was elected 

 a Fellow of the Royal Astronomical Society in 1876. 

 When the shortlived Selenographical Society was 

 formed, in 1878, he was elected its secretary. He 

 helped much in bringing out the fourth edition of 

 the amateur astronomer's vade mecum, Webb's 

 " Celestial Objects for Common Telescopes." For 

 some years past he has contributed the monthly 

 " Face of the Sky " to our contemporary " Know- 

 ledge." On June ist acute bronchitis very 

 suddenly made him its victim at the all too early 

 age of forty-two. The writer feels deeply the loss 

 of a personal friend, who spared no pains, if he 

 could render help, in giving or seeking out infor- 

 mation in astronomical matters, and that on many 

 occasions during the past twenty-two years.
