November, as deduced from the depression of the maximum of the 5th

In the chart accompanying this report (Pl. 4), the line representing the 
deviation from symmetry by *300 inch, or in other words, that line of country 
on which the maximum of the 5th did not attain the elevaticn of that of the 
12th by this quantity, is probably the best determined ; it appears to have 
passed a little to the north-west of Cornwall, to the south-east of Pembroke- 
shire, north-west of Brecon, west of Nottingham, and south-east of Newcastle. 
The *250 inch line is also well determined by the observations at Helstone, 
Weston, Gloucester, Cirencester, and Nottingham. The observations at 
Helstone, Brecon, Gloucester, and Nottingham mark out very distinctly the 
direction of the line ‘260 inch; this line passes very near and to the west 
of Helstone, *258; it then proceeds along the coasts of Cornwall and 
Devonshire, crosses the Bristol Channel, enters Wales, and continues its 
progress across Glamorganshire towards Brecon, which it leaves to the 
north-west, ‘270 inch being the value at this station. It is at this point 
that it appears to undergo a decided inflexion, its course being changed 
rather abruptly as it proceeds to Gloucester, which city it passes through. 
Nottingham is removed °025 from it to the west ; and the bend in the cen- 
tral parts of England is very considerable to bring it again to its original 
direction, as it leaves the land at the *south-east angle of Yorkshire and 
enters on the German Ocean, These lines of equal deviation from sym- 
metry present a very remarkable characteristic, namely, a decided inflexion 
over the land forming the central parts of England. This inflexion is borne 
out by the London and Ramsgate observations, presenting higher values of 
these differences than they would have done had the lines extended across 
England without inflexion. The general direction of the lines in the cen- 
tral and south-east parts of England is S.W. to N.E. The observations from 
Scotland and Ireland indicate that the general direction in those localities — 
approached nearer to that of the meridian; the lines are, however, inflected 
as they pass over the land. The chart exhibits two systems of inflexion, 
viz. that of Ireland and England, the general direction of the lines under- 
going a change as the line of greatest symmetry is approached, the inflexion 
being governed apparently by the masses of land; and the other in Scot- 
land, the observations at the Orkneys, St. Vigean’s, and Largs affording
