wires, with my watch, which makes four beats in a fecond of 
time. If any thing the difference was fomething more than a 
fecond of time : the little ftar may therefore be fuppofed to precede 
(3 Scorpii 17" in right afcenfion. By obfervations made with the 
10 foot ledor on feveral nights, while /3 Scorpii and the little ftar 
were pafting the field of the telefcope, I found the little ftar to 
be exadtly 14" N. of (3 Scorpii in declination. For June 24 
the difference was 12", 5. July 21, 13", 6. July 22, I 4 ,/ j 7 * 
July 23, 1 s", 3 : Au gulf 14, 12", 9. Auguft 17, 14", 8. . 
The bright ftar in the foot of the Centaur, marked a. in the 
catalogues, when viewed through a telefcope, becomes divided 
into two flats, one of which is about the fecond, and the othei 
about the fourth magnitude. They were both obferved by the 
Abbe de la Caille. I found their diftance, by the divided objed 
glafs micrometer fitted to the refleding telefcope, to be 15" or 
16". But it. is, in a manner, impoffible to meafure the diftance 
of two ftars very accurately with this micrometer, for being 
fimilar lucid objeds, when they are brought very near each other, 
their light will be confounded together before they exadly 
coincide. 
The larger Magellanic cloud, viewed through a telefcope, ex- 
hibits a few ftars which then appear feparated to a confiaerable 
diftance from each other. Their being fo few in number, and 
fo thinly fcattered, is the reafon of this phaenomenon appearing 
fo very faint. 
The lefs Magellanic cloud, viewed through a telefcope, exhi- 
bits a very remarkable lucid nebula, with fome tolerable bright 
ftars furrounding it. The nebula appears nearly circular, about 
3' in diameter.
