The arrows represent the Horizontal Forces inmagnitude and direction. The numbers are the Vertical disturbing Forces in terms of0*0001 metric unit. When negative they are underlined. Lines of no VerticalForce disturbance are also drawn. The shaded parts are regions of positive VerticalForce disturbance. A comparison of this with figs. 25 and 26 will suffice to showthat there is a close agreement between the two. Thus, in the case of the VerticalForces, we both find regions of high Vertical Force along the lines of the CaledonianCanal and the Western Isles, and on the East and West Coasts of South Scotland. mdcccxc.—a. 2 Q !98 MR.

Disturbance map of Scotland, from Mr. Welshs survey, 1857-58, SURVEY OF THE BRITISH ISLES FOR THE EPOCH JANUARY 1, 1886. 299 There are a few discrepancies in the direction of the Horizontal Forces, but thegeneral agreement and occasional differences will be better discussed when we deal, aswe are now about to do, with separate districts. We propose to treat of the resultsof the two surveys simultaneously, and we think we shall succeed in showing that,although it would have been impossible to draw our conclusions from. Mr. Welshsless numerous stations, they are strongly confirmed by the deductions which we havemade from his survey. Fig. 24#
