But upon Dr. Gall's theory how many and what obvious advantages result! Nor are they merely confined to the purposes of speculative physiognomy; the uses of his theory as applied to practice offer to us hopes scarcely less delightful than those which seemed to dawn upon mankind with the discovery of the gasses, and with the commencement of the French Revolution, and in these later days with the progress of the Bible Society. In courts of Justice for instance how beautifully would this new science supply any little deficiency of evidence upon trial! If a man were arraigned for murder, and the case were doubtful, but he were found to have a decided organ for the crime, it would be of little matter whether he had committed the specific fact in the indictment, or not; for hanging if not applicable as punishment, would be proper for prevention. Think also in State Trials what infinite advantages an Attorney General might derive from the opinion of a Regius Professor of Craniology! Even these are but partial benefits. Our Generals, Ministers, and Diplomatists would then unerringly be chosen by the outside of the head, though a criterion might still be wanted to ascertain when it was too thick and when too thin. But the greatest advantages are those which this new system would afford to education; for by the joint efforts of Dr. Gall and Mr. Edgeworth we should be able to breed up men according to any pattern which Parents or Guardians might think proper to bespeak. The Doctor would design the mould, and Mr. Edgeworth by his skill in mechanics devise with characteristic ingenuity the best means of making and applying it. As soon as the child was born the professional cap, medical, military, theological, commercial or legal, would be put on, and thus he would be perfectly prepared for Mr. Edgeworth's admirable system of professional education. I will pursue this subject no farther than just to hint that the materials of the mould may operate sympathetically, and therefore that for a lawyer in _rus_ the cap should be made of brass, for a divine of lead, for a politician of base-metal, for a soldier of steel, and for a sailor of heart of English oak.
