 by two variations superposed upon each other, having diderent 

 laws and bearing different proportions lo each olhor in differenl 

 parts of the globe. At Iropical stations the infliicnce of what 

 have been hitherlo called the irregulär disturbances (muynetic 

 atorms), is comparatively feeble; but it is otherwise at stations 

 situated as are Toronto (Canada) and Hobarton (V^an Diemen-

 greater, and amounts to a clearly recognizable part of the whole
