458 TH. BRÉDIKHINE, 



tigkeit ist die folgende Notiz : «Last night (8-th May) two tails were visible 

 — one fairly bright and the other very faiut. The bright tail formed au 

 angle of 45°, and the faint one 30°, with the horizon. The tails, of course 

 pointed towards the south, i. e. away froin the Sun». — Nach einer Rech- 

 nung von Dr. Strömgren betrug zu der angegebenen Zeit der Winkel der 

 Richtung (Comet — Sonnen- 180°) mit dem Horizont 53°, so dass also 

 diese Richtung mit dem Hauptschweif einen Winkel 8°, mit dem Neben- 

 schweif einen Winkel von 23° bildete. Dr. Schorr theilt mir ferner zwei 

 Aquarelle (Mai 5 und 11) und eine Bleistiftzeichnung (Mai 15) mit, welche 

 Herr A. Otten in Lima, Peru, vom Cometen angefertigt und der Ham- 

 burger Sternwarte iibersandt hat. Die Zweitheiluug des Schweifes ist deut- 

 lich sichtbar; die Länge betrug Mai 5 — 6?5, Mai 11 — 12° — resp. 10°, 

 Mai 15 —12°; der Winkel beider Schweife circa 11°.» 



Les observations importantes sur la forme de la comète se trouvent 

 dans l'article de M. D. GilF). 



On April 24, at 2 '54'" P. M., a telegram was received as follows: 



From Arthur Hill, Queenstowu. 



R. Obs., Cape Town: «Saw a Comet this morning at 5 o'clock due 

 East». 



The following morning (April 24, astronomical time), the cornet wa- 

 seen by M. Innés, M. Luut and myself. 



M. Innes's drawing represents the comet as seen with the naked eye 

 on April 24, the formation of the head being drawn with the assistance of 

 the télescope (PI. I, avril 24). 



Mr. Lunt's drawing of the comet on May 12 gives a very exact re- 

 présentation of naked-eye view of this remarkable object. 



The spectrum of the comet appears to be continuons; at least, with 

 the means of our disposai, we hâve been unable to detect any bright lines. 



Observations by Mr. Innés. — 1901 April 24. . . . It was a brilliant 

 object with a bright nucleus and a tail about 10° in length, curved on the 

 Southern side. The colour of ail was a very deep yellow, but the comet was 

 very near the horizon. Through the 10-inch guiding télescope (uow in 

 broad daylight) the yellow tint of the nucleus was very raarked. There was 

 no соша visible, the tails springing directly from the nucleus. By compa- 

 rison with Mercury, the nucleus was estimated to be two-thirds of Mer- 

 cury 's diameter, which makes it about 4"; its brightness was about equal 

 to Mercury's.
