Almost all the important States had Second Chambers in olden days, but Turkey and Bulgaria have dispensed with them. The Second Chambers are regarded as an essential element of feudal constitutions. They are the exceptions to the rule of the Constituent units not to have any Second Chambers anywhere. In the U.S.S.R. and in the Union of South Africa the Constituent units are all unicameral. In the Dominion of Canada we find that out of eight Provinces only two have Second Chambers. In the case of Switzerland out of 18 Cantons, except two, all the other 16 are unicameral. In Weimar Germany half the States were unicameral.
