ip. h Draconis, near fl. 19. 
Sept. 10. One of the mod minute of all the double ftars I 
have hitherto found. It is the fmall teleicopic ftar 
near the preceding h Draconis. Confiderably unequal. 
Both dufky w. inclining to r. With 460, they feem 
in contact ; I have however had a very good view of 
a fmall dark divition between them. Pofition (by 
exad e&imation) 2^ or 30° f. preceding. They are 
too minute for any micrometer I have. It is in vain 
to look for them if every circumftance is not fa- 
vourable. The obferver as well as the in dr u men t 
mull have been long enough out in the open air to 
acquire the fame temperature. In very cold weather, 
an hour at lead; will be required ; but in a moderate 
temperature, half an hour will be fufficient.
