Japanese Islands, who have been modified more or less by association with the latter people. =Technical and Popular Names.=--In a paper criticising the multiplication of local names in geology, Prof. C. E. Keyes distinguishes between names devised with a conscientious desire to better the condition of a science by clothing the new ideas with simple words and those which are the product of a name-making mania. "The first can not be too highly commended, nor the second too deeply deplored." Every progressive science must discard the names that have served their purpose, and must be prepared to receive all of the new ones demanded. The sciences have each two phases, for each of which a terminology is demanded, in one of which the names must be technical and special, established primarily for the investigator, and in the other general, popular, simple, and free from technical appearance; but the distinction is rarely made. Those who object to the prevalence of technical names in other sciences seldom reflect that they have them in their own art. Yet if a man of science should desire to familiarize himself with the artisan's work, "he would be, after five minutes' talk with a machinist or electrician, confronted by so many unfamiliar terms--technical terms of everyday use--that he would at once cry out for greater simplicity of language." In the geological sciences the technicalities play the same part they do in the arts and in business. Every new name in geology, however, must be properly defined before it can be noticed, and its subsequent career will depend on its utility. It may be said that no greater boon to the working geologist has been devised than the plan of designating geographically geological units irrespective of exact position or age. Since its adoption a vast mass of valuable information has been obtained that was previously unthought of, and is in a shape to be always used; the other departments of geology have been much aided, and stratigraphical geology has been greatly helped.
