eirrocumulus and cirrostratus appeared ; some dark clouds 
of smokelike texture, and whose darkness did not appear 
to arise from the interception of light by the interposiuor 
of other clouds between them and the sun, took on the: 
mottled arrangement like flimsy cirrocumtlus. The cirro- 
cumulus at 11 P.M. covered the sky with the high tem- 
perature of 60°, and barometer at 30.25. Wind southerly,

* To express my view of today, I say that the air seems to have too 
much of the deposited aqueous particles for its electricity to embody and 
‘ive form to, in the production of regular modifications. 
+ It had been 74 in the day, even when cloudy. 
$ The same disposition of the atmosphere and clouds which appeared 
yesterday night continued till eight this morning, which may be regarded as 
the period of the change to rain which the clouds of last night prognosti- 
cated.
