The night, which had been remarkably fine, cloudless, and unusually favourable 
for delicate observations, on account of the extreme steadiness of the stars, which 
enabled me to keep them bisected by the wires as long as I pleased, suddenly be- 
came bad ; a dense fog in less than five minutes after the instrument was placed 
upon this star, rendered all the stars, Jupiter and Saturn, invisible •, the Moon’s 
place also was scarcely to be distinguished. It has frozen all day : the thermometer 
in the shade stood between 29 0 and 31 0 : it now indicates 28°. The instrument is 
covered with hoar frost, and the fog is so severe that I cannot see across the garden, 
a distance from the observatory not more than 100 feet.

The small star is so excessively faint, that it will not bear even the slightest illu- 
mination ; and the measure here given was the result of half an hour’s attention.
