OF THE GLOBE. 219 



In comparing the theory with observations made round the 

 Transatlantic Pole, the results are equally satisfactory. The 

 third column of the following table is calculated from the for- 

 mula T — 86°. 3 Sin. D — 3°£, and the Pole is supposed to be 

 situated in 80° N. Lat. and 100° West Long, *, and to have a 

 temperature of — 3°|.

* If we suppose that the observations in West Greenland, and those about Hud- 

 son's Bay and Labrador, are best fitted to give the position of the Pole, it is ob- 

 vious, that it should be removed a little from the former, and brought nearer the 

 latter, so as to be placed a degree or so farther South. This change would also 

 produce a greater coincidence with Captain Parry's observations.
