Rain \(in:16 days) see ee ok 1-74 inch. 
About 0°75 inch of rain appears to have fallen in the 13 days during which the 
observations have been interrupted. The column heretofore given to the results of 
the evaporation guage will now be allotted to the whalebone hygrometer of De 
Luc, noted at nine a.m. The instrument employed was previously adjusted, sa 
that its zero represents the hygrometric state of air long exposed in a close vessel 
to quick-lime, and 100° that of air similarly exposed to water. It is found to- 
Fanye at present 15° or 20° from the mean state, in which it is noted, towards the 
Moist extreme in the night, and the dry in the day,
