The boroughs that had hitherto elected two members, and were entitled to the same number under the new scheme, remained single constituencies for the election of those two members. Of these boroughs there are twenty-three,[199:2] which, with the City of London, and the three universities (Oxford, Cambridge, and Dublin), makes in all twenty-seven cases where two members are elected together. All the other constituencies are single-member districts, a result which was brought about by a partition of the counties, of boroughs with more than two members, and of the new boroughs with only two members, into separate electoral divisions, each with its own distinctive name. It may be interesting to note that the Reforms of 1832 and 1867 did not change the total number of members of the House, but merely redistributed the existing 658 seats. By the disfranchisement, after 1867, for corrupt practices, of four boroughs returning six members, the number was reduced to 652; and the Reform Act of 1885 increased it to 670, where it has since remained. [Sidenote: Inequalities in Representation.] The distribution of seats under the Act of 1885 was only a rough approximation to equal electoral districts; and in time it has become far less close, until to-day the difference in the size of the constituencies is very great. The smallest is the borough of Newry in Ireland, which had at the census of 1901 a population of only 13,137; or, if we leave Ireland aside on account of its peculiar conditions, the smallest in Great Britain is the city of Durham with a population of 14,935; while the largest is the southern division of the County of Essex, with 217,030 inhabitants; so that the largest constituency to-day is nearly fifteen times as populous as the smallest.[200:1] Nor are the inequalities confined to extreme cases; for they exist in lesser degree throughout the electoral body, many of the constituencies being two or three times as large as many others. But unless one assumes that the exact equivalence of all votes is a fundamental principle of political justice, differences of this kind are of little consequence, provided one part of the community, or rather one set of opinions or interests, is not distinctly over-represented at the expense of another. Now, in Parliament an over-representation of this kind does exist; not, indeed, in regard to the different social classes or economic interests in the nation--for inequalities of that sort are not marked enough to be important--but between the different parts of the country.
