302 Sir H. H. Howorth—On the Arctic Lands. 
leneth of fault to the westward, the slip-area reaching to, and 
perhaps including, that of the first shock ; its eastern lateral margin 
being shorter than the western owing to that shock having previously 
relieved the strain. 
I am not aware that any fault has been traced by purely geological 
evidence in the position indicated above. But I have little doubt 
as to its existence there. Moreover, the direction and hade of the 
suggested fault are in accordance with the known geological struc- 
ture of the district. It would seem indeed that these shocks are 
indices of the latest of the long series of movements that have 
produced the English Channel. 
Authorities.—Six of the records on which the preceding account is 
founded are taken from the “Falmouth and Penryn Times” for 
May 21, and I am indebted to the courtesy of the Editors of this 
newspaper and also of the ““Western Morning News” (Plymouth) 
for inserting letters from me asking for observations on the shocks.

By Sir Henry H. Howorru, K.C.I.E., M.P., F.R.S., F.G.S. 
N my recently published book on the “ Glacial Nightmare ” I have 
tried, among other things, to show that the traces of glacial 
action in the northern hemisphere, instead of being circumpolar, are 
in fact limited to one half only of the hemisphere, namely, that 
bounded on the East by the White Sea and on the West by the 
river Mackenzie. This conclusion is of course not new, and I have 
merely collected and condensed the evidence of many witnesses to 
it. I have further suggested as possible, that while Scandinavia, 
Finland, and the British Islands were the homes of very large 
and extensive glaciers, the lands now occupying the Polar Sea were 
in a very different condition, and anything but the homes of wide- 
spread ice action. 
Before I prosecute the issues further, which you have allowed me
