After these follow tables of monthly means for 117 stations in 
North America and Newfoundland, as also tables of observations 
made by the North Pole expeditions at various places. 
Next follow tables of monthly means for 43 stations in Bohe- 
mia and Wurtemburg, for 27 stations in England and Scotland, 
and for 30 stations in Germany, Switzerland, and the Austrian 
dominions, making in all, in the two parts of the work, 291 
stations. 
Then follow tables, showing, first, the mean temperature of 
every five days in the year, for the 8 stations mentioned above, 
drawn from the whole number of years of observation ; secondly, 
the deviations in each single year from the general means. 
In order to determine the magnitude of the local deviations, 
two systems of stations are formed ; the first contains 32 stations,
