The stars are not steady j and the deposition of moisture on both surfaces of the 

 object-glass is so copious and rapid, that although well wiped off, before the instru- 

 ment can be replaced upon the star it re-collects, and compels me to discontinue 

 the observations ; a circumstance much to be regretted, for the night is beautifully 

 clear. Thermometer in the Observatory stands at 28°.
