Remarks on the Quantity of Rain at Different Heights. 163 



science in our country make itself known and felt by its benefi- 

 cial results to society ; and not the least among them will be 

 such as follow the investigation of the laws governing the 

 different states of the atmosphere. 



With the apparatus mentioned above, the following results 

 have been obtained ; premising, however, that during the 

 months of winter no record of the difference was kept, as the 

 drifting of the snow and other causes rendered the observations 

 not reliable. A record was kept of the direction of the wind, 

 the height of the mercury in the dry and wet bulb thermometers, 

 with the relative humidity and force of vapor, the duration of 

 the rain storms, as well as the quantity of water collected in 

 each gauge. To note all these circumstances in this paper 

 would make it too long, and be interesting to only a few, there- 

 fore the asrsregate results for each month will be mentioned. 



The greatest monthly difference was in July, 1855, when it 

 Was 2.02 inches ; the greatest in any one storm, was in No- 

 vember, 1854, a difference of 1.18 inches, the storm was of 

 about twenty-two hours' continuance, and the wind, West.
