428 SCIENTIFIC RECOED FOR 1885. 



Mereny. — Vol. II will be published in 1885. Spectrum observations 

 of /S Lyrse have confirmed the variability of the spectrum of this star. 

 Many other spectroscopic observations of stars, planets, and comets 

 have been made. 



Hong-Kong. — Largely devoted to meteorological observations, weather 

 reports, &c. The new time-ball was dropped daily at 1 p. m., Sundays 

 and holidays excepted. Observations of the moon and of Jupiter's sat- 

 ellites have been obtained. 



Karlsrulie (1884). — The principal work of the observatory is the de- 

 termination of the xjositions of southern stars to 8th magnitude, inclusive. 

 In the zone 0° to —4°, 5,000 observations have been made, and the zone 

 —4° to —7° has been commenced. The single positions have probable 

 errors of ±08-028 and ±0"-39. The 6-inch refractor has been re- 

 mounted. 



Kei€. — Sketches of sun-spots have been made on one hundred and 

 seventy-six days, in order to continue Schwabe's enumeration. The 

 rating of time-pieces and the examination of sextants, meteorological 

 instruments, &c., is continued, 



Kiel (1884). — The equatorial has been used to observe 2 2164 for par- 

 allax, by Dr. Lamp. New comets were regularly observed. The me- 

 ridian circle is used to determine the positions of stars between 79° and 

 82° north. The zone catalogue (55° to 65°) is in preparation. 



Leipzig (1884). — A 6-iuch heliometer by Eepsold is in process of con- 

 struction and will be delivered at the end of 1886. A universal instru- 

 ment has been ordered, with which a long series for latitude will be 

 commenced. Ten thousand five hundred and forty-one observations 

 (123 zones) of zone stars have been made in the new zone (+5° to -f 10°) 

 and the reductions for the old zone (+10° to +15°) are in progress. 



Leipzig (1884) (private observatory of Dr. Engelmann). — Two thou- 

 sand six hundred observations of 430 double stars have been made, 

 mostly of Struve's doubles. An investigation of the constant errors is 

 in progress. It appears that the difference in the magnitude of the com- 

 ponents influenced the constant errors in a marked degree. Otto Struve's 

 list of double stars for comparison has been observed ; about 500 meas- 

 ures have been obtained. 



Leyton (Mr. Barclay's observatory). — Double-star observations and 

 observations of the phenomena of the satellites of Jupiter and Saturn 

 are continued. 



Licit Observatory. — All the buildings for the observatory proper are 

 now completed except the dome for the large equatorial. A suitable 

 dwelling house has been erected ; others will be required. All the princi- 

 pal instruments of the observatory but one have been designed, ordered, 

 constructed, inspected, and are now suitably mounted, so that observa- 

 tions could be at once begun. This instrumental equipment consists 

 of a 12-inch Clark equatorial ; a Repsold meridian circle of essentially
