136 Correspondence — Rev. 0. Fisher — Mr. Clement Reid. 
In Fig. 2 Mr. Milne lias now sliown us the highest cone which 
could float with its vertex upwards ; and tkereby proved tkat I was 
right in saying that a berg of the “ shape ” he had “ figured ” in his 
former paper “would not remain in that position, but must turn 
over.” 
Your readers will no doubt join with me in thanking Mr. Milne 
for his calculations, which I conceive may be thus summarized. If 
the 
(1) Diameter of base of cone of ice is less than -f the height, it 
will float on its side. 
(2) Diameter is greater than f the height, it will float with its 
vertex downwards. 
(3) Diameter is greater than twice the height, it may float with its 
base downwards. 
(4) Or, since this case is included in (2), it may float with its 
vertex downwards. 
However, when the diameter is only a little greater than twice the 
height, it would ajipear that the more stable position of the two 
would be with the vertex downwards. 0. Fisher. 
MODERN DENUDATION IN NORFOLK. 
Sir, — The following facts concerning recent destruction of the 
Norfolk cliffs seem to be of sufficient interest to induce me to beg 
your insertion of them in your Magazine. 
On Tuesday, January 30th, we had a severe gale, which did much 
harm all along the coast. The coincidence of a spring-tide and a 
high wind from the W.N.W., brought the sea to a height it lias not 
been known to reacli for at least forty years. I have examined 
the coast from Hasborough to beyond Sherringham, and the damage 
done is marvellous. Probably the loss of land along the whole line 
of coast mentioned may be estimated at a yard. At the life-boat gap 
Bacton the arnount that has gone is fifteen yards, and a strip of 
about that width is missing as far as the Walcot gap (three furlongs). 
At Bacton the cliffs are low, so the denudation is greater than in 
other parts. 
Mundesley has had part of the life-hoat gangway swept away, and 
sonie walls tlirown down, besides the land lost. 
At Cromer people are congratulating themselves on the small 
arnount of damage done ; it is said that £150 will cover it. Düring 
the gale it was tliought that the jetty would be pulled up bodily by 
the upward force of the waves; but fortunately the planks gave way, 
and there are only about fifty missing. The gangway at the north 
end of the town has been swept away ; but as it was only made of 
earth, that will not much matter. 
The most serious loss is at Lower Sherringham. There Mr. 
Upscher has lost two acres ; nearly all the sea-wall has been swept 
away : none of the gangways are left ; a cottage and a shed have 
fallen into the sea; the inn on the cliffs has had the Windows broken, 
and is in a very unsafe condition ; and should another gale occur 
now, much of the village will go.
