METEOROLOGICAL OBSERVATIONS. 391 



19' east of Greenwich. Moscow-is situated in latitude 55^ 46' nortli 

 and Longitude 37*^ 36' east, the former is about 21 feet above the kvel 

 of the Neva or Baltic sea, and the latter is by the levels of the St. 

 Petersburg and Moscow Railway about 650 feet above the Baltic sea, 

 and is situated 460 miles in the interior, and away from any large body 

 pf water. 



The tables will better speak in detail for themselves, but in ageneral 

 way a few remarks may be made on them as follows. In the barome- 

 tric table it is very remarkable that the rise and fall of each month is 

 the same in each of six cases although not actually equal, indicating 

 some general law of atmospheric density in this northern hemisphere. 

 Thus the highest month is different as well as the lowest, but the 

 difference is slight. 



.The differences of the elevations will, of course, account for the 

 y,aried means, or heights in inches which may be briefly recounted 

 thus :

 ~The barometric heights are modified by local circumstances. 



The thermometric tables will be found of considerable interest, from

 be seen that St. Mary's is a little the warmest in summer, being in July
