184 EECORD OF SCIENCE FOR 1887 AND 1888. 



subsidiary apparatus there is a cylindrical chroiiogiapli, Barraud & 

 Lund; a fillet clironograpb, made in 1807 by direction of Commodore 

 Maury; a sidereal clock, by F. Vazquez, Mexico; sidereal and meau-time 

 clocks, by Barraud & Luud ; two sidereal chronometers, by Negretti & 

 Zambra; seven mean time chronometers, by various makers, and niag- 

 netic and meteorological instruments. A photographic refractor of 

 0">.33 (13 inches) aperture and 3"\43 (11 feet) focal length has been or- 

 dered from Grubb, to enable the observatory to co-operate in the inter- 

 national plan of charting the sky by photography. The personnel con- 

 sists of Sr. Ingeneiro Angel Anguiano, director; Sr. Ingeneiro Felipe 

 Valle, Sr. Ijieut. Col. Teodoro Quintana, Sr. Ingeneiro Francisco Rodri- 

 guez Rey, Sr. Apolonio Romo, Sr, M. Moreno; two more astronomers 

 will be added during 1889. The work of the meridian circle has been 

 upon comparison stars, comets, and asteroids; the 15-inch equatorial 

 has been used upon comets, and asteroids, and these bodies, as well as 

 a list of southern nebuliTe, will be carefully observed in future. The 

 I^hotoheliograph has been used almost daily, and with the alt-azimuth 

 observations for time and latitude have been made, and observations of 

 lunar culminations and of comets. Considerable time has been devoted 

 to co-oi^erating with longitude parties. The ])osition of the observatory 

 is: Latitude, -f 19° 24' 17".5; longitude, C' 3i?" 40^53 west of Green- 

 wich (determined telegraphically from St. Louis); altitude 2,322'" (7,G18 

 feet). An "anuario" is published regularly. 



Tacuhaya.—Pnvsite observatory of M. G. Pricto : Bardou equatorial, 

 0^.11 (4^^ inches) aperture, 1"'.G0 (5 feet 3 inches) focal length; spectro- 

 scope, and clock. 



Taschkent. — The refractor has been used for observations of sun-spots, 

 comets, and occultations by the moon ; the meridian circle, principally 

 for determining the positions of comet comparison stars. The observa- 

 tory has co-operated in determining the geograi>hical positions of a num- 

 ber of places in central Asia. Several chronometers have been tested, 

 and the noon signal has been given by the discharge ^f a cannon, as in 

 previous years. The director, M. Pomerantzeff, is assisted by MM. 

 Zalessky and Schwarz. A new determination of the latitude in 1887 

 gave: ^=+41° 19' 31".35±0".05. 



Temple observatory {Rmjhy). — Spectroscopic observations of the motion 

 of stars in the line of sight, and measures of double stars. 



Toldo. — An observatory was founded in 1888 at Tokio, Japan, by 

 combining the astronomical department of the old Marine observatory, 

 the observatory of the Ministry of the Interior, ar^d that of the Impe- 

 rial University. The new observatory occu])ies the buildings of the 

 Marine observatory, its position as provisionally determined being lati- 

 tude, +35° 39' 17"."); longitude, 9'' 18"' 58«.0 east of Greenwich. The 

 principal instruments are a SJ-inch Kepsold transit, a 5 inch Merz and 

 Repsold meridian circle, and equatorials of G^ and 8 inches aperture. 

 The director is H. Terao.
