In taking the mean of the observations, those on the 14th and 

 ibose of the morning of the 15th are rejected, being so great; 

 and it is remarkable that this excess continued only on the 

 falling of snow. On the weather clearing up prior to observing 

 the noon variation of the 15th, it had decreased. The noon 

 observation of the 20th is likewise rejected : this increase Wa» 

 attended with drizzling rain.
