Overview

Excerpt from The Scientific Memoirs of Thomas Henry Huxley, Vol. 2 of 4 In a lecture given by Mr. Faraday at the Royal Institution on the 7th of June, 1850, and briefly reported in the 'athenaeum' and Literary Gazette' for the same month, it was shown that when two pieces of ice, at 32 Degrees Fahr., with moistened surfaces, were placed in contact, they became cemented together by the freezing of the film of water between them. When the ice was below and therefore dry, no adhesion took place between the pieces. Mr. Faraday referred, in illustration of this point, to the well-known experiment of making a snowball. In frosty weather the dry particles of ice will scarcely cohere, but when the snow is in a thawing condition, it may be squeezed into a hard compact mass. On one of the warmest days of last July, when the thermometer stood at upwards of 80 Degrees Fahr. In the shade and above 100 Degrees in the sun, a pile of ice-blocks was observed by one of us in a Shop window, and he thought it interesting to examine whether the pieces were united at their places of contact. Laying hold of the topmost block, the whole heap, consisting of several large lumps, was lifted bodily out of its vessel. Even at this high temperature the pieces were frozen together at the places of contact, though the ice all round these places had been melted away, leaving the lumps in some cases united by slender cylinders of the substance. A similar experiment may be made in water as hot as the hands can bear two pieces of ice will freeze together, and sometimes continue so frozen in the hot water, until, as in the case above mentioned, the melting of the ice around the points Of contact leaves the pieces united by slender columns of the substance.
