Dr. Bigelow has had the honor of naturalizing, if not of inventing, the name of the Institute before which he delivered this address. His work on the Elements of Technology was the first in which this name appeared, at least in recent times. It designates that class of sciences which bear on art,--sciences of practical application. Dr. Bigelow, in this address, places himself emphatically with those who believe that mental discipline can be obtained as well by useful as by useless studies, and who think it a waste of time "to spend five years of the most susceptible part of life in acquiring a minute familiarity with tongues which are daily becoming more obsolete." We welcome this address as an important ally for those who desire that our schools and colleges shall not insist that every young man wishing for their advantages shall devote one half of his time to the details of Greek and Latin Grammar and Prosody. Dr. Bigelow is no rash reformer, no youthful enthusiast, no reckless radical. He has the confidence of the whole community for his science, scholarship, and ripe judgment. When, therefore, a man of his character and position, without passion or prejudice, publishes the conclusions which this address contains, we may hope that a change is at hand in the course of study now pursued in our colleges and universities, and in the schools which prepare for them. Dr. Bigelow does not desire Latin or Greek to be excluded from the college course; but he thinks that "under the name of classical literature they premise and afterward carry on a cumbrous burden of dead languages, kept alive through the dark ages, and now stereotyped in England, by the persistent conservatism of a privileged order." He thinks that the mind might be disciplined and trained quite as well and more cheaply by other studies than that of the Greek language. He is of opinion, that, if Greek should once cease to be made a requisite in our universities, though it would be studied still by a certain class, it would never be adopted again as an indispensable academic study.
