During the rather more than half a century that elapsed between the Corporations Act of 1835, and the Local Government Act of 1888, the chief reforms effected were in the province of sanitary administration, were mainly due to the efforts of individuals, such as Mr Stansfeld in 1872, and were generally incorporated in the Public Health Act of 1875. These sanitary measures contained the principle on which the area of the United Kingdom was finally redistributed. For the purposes of County Councils, England is mapped out into sixty-one administrative counties. Each of the electoral divisions of which the County consists has a Councillor of its own. The electors are practically almost identical with the parliamentary constituencies. In the case of municipalities inside the County area, the Local Government Board decides the share of representation to which it is entitled, and allots to it on the Council one or more members, as the case may be. In addition to the councillors created by purely popular election, a certain number of aldermen, not to exceed one-fourth of the whole body are chosen by co-optation among the Councillors themselves. The term of Council office is three years. The chairman, however, who is not forbidden to receive a salary, holds his place only for one year. Like the District chairman, the County president too, without satisfying any pecuniary qualification, becomes, by virtue of his office, a County magistrate.[29] Like the Council electors, the chairman and the six co-opted aldermen are subject only to the condition of having the County vote. As in parliamentary elections so in County elections, the polling is by ballot. The incidental expenses, however, which are strictly regulated by the number of the constituency, are defrayed, not by the candidate or his friends as in parliamentary competitions, but out of a County fund. The prerogatives of magistrates in whatever appertains to the licensing of public houses, and exercised in Quarter and Special Sessions, are untouched by the new bodies. With that exception, the functions of Quarter Sessions are superseded practically by the Councils. As a consequence, the sessional attendances of the magistrates have largely fallen off; though there still exist many opportunities for joint action between the new Councils and the old Sessions. For instance, the County police is controlled by a committee whose members are selected from the old magistrates and the new Councillors. Again, when the object is to acquire fresh land for popular use; to open or endow local museums or libraries, to establish emigration funds to the Colonies or elsewhere, united action between the two bodies is usual, but not compulsory.
