Regelation was observed by these philosophers in carefully arranged experiments with prepared surfaces fitting together accurately, and kept in contact sufficiently long to allow the freezing together to take place.
We know that at 32° Fahrenheit, regelation renders the mass continuous, and that it becomes brittle only at a temperature below this.
I question, however, the statement, that regelation takes place by the freezing of a film of water between the fragments.
C] Regelation also appears to have attracted his notice.
He approached it cautiously, treading down the snow to give it compactness, and thus make his footing sure as he advanced; bringing regelation into play, he gave the mass the necessary continuity, and crossed in safety.
When the attachments of pressed ice are broken, the continuity of the mass is restored by the regelation of the new contiguous surfaces.
Regelation is the complementary effect to the above; for here the superficial portions of a mass of ice are made virtually central by the contact of a second mass.
He offers it in substitution for my views as the best argument that he can adduce against them; he also controverts the explanations of regelationpropounded by Prof.
Regelation also enables two tributary glaciers to weld themselves to form a continuous trunk; thus also the crevasses are mended, and the dislocations of the glacier consequent on descending cascades are repaired.
It is this same principle of regelation which enables men to cross snow bridges in safety.
Mr. James Thomson had referred regelation to the cold produced by the liquefaction of the pressed ice; but in the above experiment all pressure is not only taken away, but is replaced by tension.
An hydraulic press may of course be employed in this experiment, but it is not necessary; with the hammer and plug beautiful rings of ice are easily obtained by the regelation of the crushed fragments.
As already remarked, the formation and motion of glaciers, and other points of a kindred nature, had been referred to regelationlong before I occupied myself with the cause of regelation itself.
But, according to Faraday's explanation, the strength and quickness of the regelation must also go hand in hand with the magnitude of the pressure employed.
There are brass shapes used for the casting of flowers and other objects which answer admirably for experiments on the regelation of ice.
Bringing all the parts into contact, they were cemented through regelation to form the claret-glass sketched in fig.
The ice morsels did so, and immediately regelation again set in.
The difficulty referred to above is thus stated by Helmholtz: 'In the explanation given by Faraday, according to which the regelation is caused by a contact action of ice and water, I find a theoretic difficulty.
Both Professor Helmholtz and I have since agreed to consider the physical cause of regelation an open question.
Faraday, who discovered this phenomenon, named it the regelation of ice.
The revival of this subject by Professor Helmholtz has caused me to make a few additional experiments on the moulding and regelation of ice.
On both theories, therefore, the strength and quickness of the regelation ought to correspond to the magnitude of the pressure.
This latter question is not once referred to in the memoir in which the regelation theory was first developed.
In fact, regelation will confer upon it all the appearance of viscosity.
But a little further down the wound is healed again, and regelation has restored the smooth surface of the glacier.
I have already made the usual regelation experiment before you when I compressed broken ice in this mould.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "regelation" in a variety of sentences. We hope that you will now be able to make sentences using this word.
