horizon,--and, like the horizon, it always flies before them. The geometricians and the chemists bring, the one from the dry bones of their diagrams, and the other from the soot of their furnaces, dispositions that make them worse than indifferent about those feelings and habitudes which are the supports of the moral world. Ambition is come upon them suddenly; they are intoxicated with it, and it has rendered them fearless of the danger which may from thence arise to others or to themselves. These philosophers consider men in their experiments no more than they do mice in an air-pump or in a recipient of mephitic gas. Whatever his Grace may think of himself, they look upon him, and everything that belongs to him, with no more regard than they do upon the whiskers of that little long-tailed animal that has been long the game of the grave, demure, insidious, spring-nailed, velvet-pawed, green-eyed philosophers, whether going upon two legs or upon four. His Grace's landed possessions are irresistibly inviting to an agrarian experiment. They are a downright insult upon the rights of man. They are more extensive than the territory of many of the Grecian republics; and they are without comparison more fertile than most of them. There are now republics in Italy, in Germany, and in Switzerland, which do not possess anything like so fair and ample a domain. There is scope for seven philosophers to proceed in their analytical experiments upon Harrington's seven different forms of republics, in the acres of this one Duke. Hitherto they have been wholly unproductive to speculation,--fitted for nothing but to fatten bullocks, and to produce grain for beer, still more to stupefy the dull English understanding. Abbé Sieyès has whole nests of pigeon-holes full of constitutions ready-made, ticketed, sorted, and numbered, suited to every season and every fancy: some with the top of the pattern at the bottom, and some with the bottom at the top; some plain, some flowered; some distinguished for their simplicity, others for their complexity; some of blood color, some of _boue de Paris_; some with directories, others without a direction; some with councils of elders and councils of youngsters, some without any council at all; some where the electors choose the representatives, others where the representatives choose the electors; some in long coats, and some in short cloaks; some with pantaloons, some without breeches; some with five-shilling qualifications, some totally unqualified. So that no constitution-fancier may go unsuited from his shop, provided he loves a pattern of pillage, oppression, arbitrary imprisonment, confiscation, exile, revolutionary judgment, and legalized premeditated murder, in any shapes into which they can be put. What a pity it is that the progress of experimental philosophy should be checked by his Grace's monopoly! Such are their sentiments, I assure him; such is their language, when
