In an arithmetical series one obtains an expression of the former category, in a geometrical series an expression of the latter. The mind takes note of diversity, not of difference; e.g. it notes not that an intensity difference of 2 less 1 equals one of 101 less 100, but rather that the relation of 2 to 1 is like that of 200 to 100.

An Ameri- can statesman, orator, and constitutional lawyer. He was born in Salisbury (now Franklin), N. H., January 18, 1782, studied for a few months at Exeter Academy in 1797, then was under the care of a private tutor for a short time, after which he entered Dartmoutl College, gradu- ating in 1801. After his graduation he began the study of law in an office at Salisbury, served for a few months as principal of the Fryeburg (Maine) Academy, then resumed his legal .studies at Salisbury and in 1804 removed to Boston and entered the law office of Chris- topher Gore as student and clerk. In 1805 he was admitted to the bar and began practice at Boscawen, but in 1807 removed to Portsmouth, where he soon acquired distinction. Having be- come something of a political pamphleteer and public speaker, Webster was in 1812 elected by the party opposed to the war with England to a seat in Congress and was reelected in 1814. He was placed on the important Committee of For- eign Relations, and while acting with the anti- war party, he did not go to the extreme lengths which some of the Xew England Federalists did in their opposition to the Administration. His speeches against the embargo and in favor of strengthening the na^7'. on the currency, the bank, and the tariff, were among the ablest de- livered in Congress, but in several instances they did not exhibit the broad nationalism of which he afterwards became the foremost advocate. In 1816 Webster removed to Boston, and for nearly seven years devoted himself to the prac- tice of law. He soon rose to the position of one of the foremost advocates of the country and appeared in many of the famous cases of the day, among them the Dartmouth College and the Girard Will cases. (See D.^rtmoutii College C'.VSE. ) In 1820 he served as a delegate to the convention called to revise the Constitution of Massachusetts and took a conspicuous part in the work of that body. In the same year he <le- livcred the oration at Plymouth in commemora- tion of the landing of the Pilgrims; this was fol- lowed in 1825 by an oration on the occasion of the laying of the corner-stone of the Bunker Hill Moniuuent and by a eulogy on Adams and .Tef- ferson in 1826 — three addresses which established his fame as one of the great orators of the time. In the meantime, in 1822, Webster had been elected to Congress from the Boston district, and was twice reelected by a practically unanimous vote. As chairniiin of the .Judiciary Committee he was instrumental in securing a codification of the criminal jurisprudence of the United States. He made notable speeches on the Greek Revolution and in opposition to the protective
