336 The Loiv Barometer of the Antarctic Temperate Zone. 



trated graphically in Fig. 1, which represents the height of the 

 barometer above 28J inches for different southern latitudes. 

 In the northern hemisphere there is a similar increase of 

 pressure as we leave the equator, a maximum is there also 

 attained in about latitude 30° ; but from, this point towards the 



poles there is a marked difference in the rate of diminution of 

 pressure in the two hemispheres. The following table by 

 Schow is sufficient to indicate this : —
