all wrong--what can it be? Why, sir, your mouth is not at all like what it was yesterday." "Ah! ah! I will tell you vat it ees," replied the French dentist; "ah! good--my mouse is not de same--no indeed--yesterday I did have my jaw in, but I did lend it out to a lady this day." Don't you think of this now while you are sitting. You know the trick Garrick played the painter, who, foiled in his attempt, started up, and said--"You must be Garrick or the d----!" Then as to attitude, 'tis ten to one but you will be put into one which will be quite uncomfortable to you. One, perhaps, after a pattern. I should advise you to resist this--and sit easy--if you can. Don't put your hand in your waistcoat, and one arm akimbo, like a Captain Macheath, however he may entreat you; and don't be made looking up, like a martyr, which some wonderfully affect; and don't be made turn your head round, as if it was in disgust with the body; and don't let your stomach be more conspicuous than the head, like a cucumber running to seed. Don't let him put your arm up, as in command, or accompanied with a rapt look as if you were listening to the music of the spheres; don't thrust out your foot conspicuously, as if you meant to advertise the blacking. Some artists are given to fancy attitudes such as best set off the coats, they are but nature's journeymen at the faces; don't fancy that the cut, colour, or cloth of your coat will exempt you from the penalty of their practice. Why, Eusebius, they have lay-figures, and dress them just as you see them at the tailor's or perfumer's; and one of these things will be put up for you--a mannikin for Eusebius! In such hands the coat is by far the best piece of work, you may be sure your _own_ won't be taken for a pattern. You will despise it when you see it, and it will be one you can never change--it will defy vamping. You may be at any time new varnished whenever after generations shall wish to see how like a dancing-master the old gentleman must have looked. It is enough to make you a dancing bear now to think of it. Others, again, equip you with fur and make you look as if you were in the Hudson's Bay Company. Luckily for you, flowered dressing-gowns are out, or you might have been represented a Mantelini. What can you be doing! It is difficult to put you in your positions. There are some that will turn you about and about a half an hour or more before they begin, as they would a horse at the fair--ay, and look in your mouth too. If they cannot get you otherwise into an attitude, they will shampoo you into one. And, remember, all this they will do, because they have not the skill to paint any one sitting quite easy. Don't have a roll in your hand--that always signifies a member of Parliament. Don't have your finger on a book--that would be a pedantry you could not endure. I cannot imagine what you will do with your hands. Ten to one, however, but the painter leaves then out or copies them out of some print when you are gone. This
