Of the various recent works having anything of the character of contributions to a history of Scottish society during the period in question, the richest by far, both in fact and in suggestion, are the two which bear the name of the late Lord Cockburn. Rich enough in this respect was his _Life of Jeffrey_ published in 1852; but richer still are the _Memorials of his Time_, now published posthumously. Lord Cockburn was born in 1779, and died in 1854. Consequently, it is not over the whole of the period under notice, but only over seventy years of it, that his reminiscences could in any case have extended. In fact, however, the period over which they do extend is still more limited. The _Memorials_ begin about the year 1787, when the author was a boy at school, and they do not come farther down than 1830. We think, too, that all readers of the volume will agree with us in regarding the earlier portion of it,—that which contains Lord Cockburn’s recollections of the time of his boyhood and youth,—as by far the most interesting. Nowhere else is there such a vivid and racy account of the state of Scottish society from about 1790 to about 1806. Fixing on the latter year, and remembering that Lord Cockburn’s recollections refer chiefly to Scottish society as it was represented in Edinburgh, we have in these “Memorials,” therefore, the best text possible for our present paper. First of all, the _Memorials_, taken in connection with the _Life of Jeffrey_, bring more distinctly before us than had ever been done previously, or, at all events, since the time of the Reform Bill agitation, the anomalous system of polity by which Scotland was governed not so very long ago. Such a system of polity, maintained so quietly and with such results, was probably never seen elsewhere under the sun. Nominally, Scotland was under a free representative government; but actually she was under the absolute rule of a single native. Ever since the Union of 1707, when the Scottish autonomy ended and Westminster became the seat of the one Imperial Government for England and Scotland together, that Government, except in a few instances when attempts were made to rule Scotland directly by English methods, and the attempts raised storm and whirlwind, had found it convenient to entrust the sole management of Scottish affairs to a single minister, who, by his Scottish birth and connections on the one hand, and his connections with the Cabinet and the Parliament at Westminster on the other, could act as a kind of responsible middleman. Knowing the character and habits of his countrymen, he could carry out the intentions of Government in Scotland far better than Government could do for itself; and, by his command of the Scottish votes in Parliament, he could serve the Cabinet in British and Imperial questions so effectively as to be able to dictate to it in all purely Scottish questions. This kind of depute-sovereignty, or rule
