One of the newest plans for the economical use of artificial ice has recently been patented by Van der Weyde, of Holland. The invention is based on the fact that two smooth surfaces of freshly cut ice when brought into contact at a temperature below thirty-two degrees will unite firmly. At a higher temperature the junction yields to a blow, and the ice breaks into the original parts. Van der Weyde casts blocks of ice into small cubes, which are stamped with a trade mark. These cubes are joined into a larger cube of any desired weight and sent out for use. The mark is a guarantee that the ice is pure, and the small cubes, weighing an ounce each, are easily separated into a shape convenient for use. ["Artificial Ice in Cubes," Lawrence Chieftain (Mount Vernon, Missouri), June 21, 1894]
"to glide across a frozen surface on ice-skates," 1690s, from ice (n.) + skate (n.2). The verb usually was skate until the advent of roller-skating mid-18c. made distinction necessary. A run of severe winters that froze over the Thames in the late 17c. made ice-skating popular in England. Related: Ice-skates (1862).
1570s, "weasel-like animal of Egypt," from Latin ichneumon, from Greek ikhneumon "ichneumon," literally "searcher, tracker," perhaps so called because it hunts crocodile eggs, from ikhneuein "hunt for, track," from ikhnos "a track, footstep, trace, clue," which is of unknown origin. Used by Aristotle for a species of wasp that hunts spiders (a sense attested in English from 1650s).
"stone presenting a fossil footprint," 1841, from Latinized form of Greek ikhnos "a track, footprint" (which is of unknown origin) + -lite. Ichnite in the same sense is from 1854. Ichnology, "scientific study of fossil footprints," is from 1837.
So numerous have been the discoveries of fossil footmarks in Europe within a few years past, and so many species occur in this country, that it will be at least convenient to have them designated by some appropriate scientific terms, and to arrange them in systematic order. I propose the term Ichnolite ... to include them all and to be the name of the Class. [Edward Hitchcock, LL.D., "Final Report on the Geology of Massachusetts," 1841]
"the reading of traces of footsteps to determine the nature and peculiarities of what made them," 1855, from Latinized form of Greek ikhnos "a track, footprint" (which is of unknown origin) + -mancy "divination by means of."
