People of the character here spoken of, that is, who tease you to death with some one idea, generally differ in their favourite notion from the rest of the world; and indeed it is the love of distinction which is mostly at the bottom of this peculiarity. Thus one person is remarkable for living on a vegetable diet, and never fails to entertain you all dinner-time with an invective against animal food. One of this self-denying class, who adds to the primitive simplicity of this sort of food the recommendation of having it in a raw state, lamenting the death of a patient whom he had augured to be in a good way as a convert to his system, at last accounted for his disappointment in a whisper—‘But she ate meat privately, depend upon it.’ It is not pleasant, though it is what one submits to willingly from some people, to be asked every time you meet, whether you have quite left off drinking wine, and to be complimented or condoled with on your looks according as you answer in the negative or affirmative. Abernethy thinks his pill an infallible cure for all disorders. A person once complaining to his physician that he thought his mode of treatment had not answered, he assured him it was the best in the world,—‘and as a proof of it,’ says he, ‘I have had one gentleman, a patient with your disorder, under the same regimen for the last sixteen years!’—I have known persons whose minds were entirely taken up at all times and on all occasions with such questions as the Abolition of the Slave-Trade, the Restoration of the Jews, or the progress of Unitarianism. I myself at one period took a pretty strong turn to inveighing against the doctrine of Divine Right, and am not yet cured of my prejudice on that subject. How many projectors have gone mad in good earnest from incessantly harping on one idea, the discovery of the philosopher’s stone, the finding out the longitude, or paying off the national debt! The disorder at length comes to a fatal crisis; but long before this, and while they were walking about and talking as usual, the derangement of the fancy, the loss of all voluntary power to control or alienate their ideas from the single subject that occupied them, was gradually taking place, and overturning the fabric of the understanding by wrenching it all on one side. Alderman Wood has, I should suppose, talked of nothing but the Queen in all companies for the last six months. Happy Alderman Wood! Some persons have got a definition of the verb, others a system of short-hand, others a cure for typhus fever, others a method for preventing the counterfeiting of bank notes, which they think the best possible, and indeed the only one. Others insist there have been only three great men in the world, leaving you to add a fourth. A man who has been in Germany will sometimes talk of nothing but what is German: a Scotchman always leads the discourse to his own country. Some descant on the Kantean philosophy. There is a
