ASTRONOMY. 189 



pleted, he now intenus to devote himself to lunar work — the deterniiua- 

 tioii ofselenographical long:itude and latitudeof alar^e number of i)oints 

 on the moon's surface by means of a valuable seiies of lunar pliot()grai)Us 

 at the observatory. Kefereuce is made, in addition to the Pleiades 

 work, to the existence of measures of some 250 stars in another cluster 

 made at the observatory a few years since, and to be shortly reduced and 

 published; the particular cluster is not indicated in the report, but pre- 

 sumably may be M. 39 in Cygnus, described by ]\Iessier when he ob- 

 served it in 17'J4 as "a star-cluster of 1° diameter." {Nature.) 



Radclijfe Observatory. — Has made over 3,000 transit circle observa- 

 tions on the sun (103), moon (02), and stars. 



Savilian Observatory. — Is completing" its i)hotometry of naked-eye 

 stars, and has begun the triangulation of the luuar surface. 



Temple Observatory, Rugby. — Measures of double stars are continued. 



Stonyhurst College Observatory. — Continues its meteorological work 

 and has made 281 drawings of the whole solar disk on 257 days. Atten- 

 tion is paid to the spectra of sun spots, and the protuberances are ob- 

 served. 



Leyton Observatory (Mr. Barclay's). — Is about to publish its volume V. 



Mr. Common's Observatory. — Is about to erect a 5-foot reflector for 

 photography alone. The glass disk has been on hand since J883 and 

 seems to be satisfactory. 



Lord Crawford^ s Observatory. — Vol. Ill is about to be issued. 



Mr. Crossleyh Observatory. — Has been become possessed of Mr. Com 

 men's 3-foot reflector. 



Lord Basse's Observatory. — Has been employed in measures of lunar 

 radiant heat and in drawings of Jupiter and Mars. 



Colonel Tomline's Observatory. — Has observed the comets of the year. 



Colonel TupmanU Observatory. — Has just been equipped with an 3=^- 

 inch meridian circle, a -ii-inch refractor, and an IS.J-inch reflector. 



Cape of Good Rope Observatory. — Its work is elsewhere described. 



Hong-Kong Observatory. — Is chiefly meteorological and for time-signals ; 

 but will soon possess a G-inch equatorial. 



The V. J. S. der Astronomischen Gesellschaft for 1884 contains, as 

 usual, reports from the various European observatories. The following 

 notes are condensed from these reports, and give a connected account 

 of the activity of the various establishments for 1883 : 



Athens. — The Sun was observed on 355 days ; the Moon had 534 points 

 determined in its topography ; Jupiter was drawn 03 times. 



A memoir on the comet of 1882 is nearly ready for printing ; 39,400 

 comjiarisons of variable stare were made. 



Berlin. — Dr. Becker has left the observatorj' to take charge of the 

 Gotha Observatory. 



The Zone + 20° to + 25° is tinished so far as observations are con- 

 cerned. To determine the influence of the magnitude of the stars on 

 the deduced E. A., the transits of 247 stars were observed on X3 eve-
