The two Doves are always quarrelling. Mrs. Dove is very ill-tempered, and Mr. Dove very obstinate. He will smoke cigars at home—will stir the fire with the bright poker—will bring friends home late to supper—will whistle; all of which practices Mrs. Dove abominates. She remonstrates; Mr. Dove retaliates. A tiff ensues; and Mrs. Dove goes home to her mother. Ascertain the mean difference between them; and state the amount which Dove has to pay every year in diamonds, boxes to the opera, new velvet gowns, and trips out of town. * * * * * Why are the Protectionists like walnuts? Because they are very troublesome to _Peel_. ANECDOTES OF SCIENCE. PERFECTLY ORIGINAL. STAYS were first invented by a brutal butcher of the thirteenth century as a punishment for his wife. She was very loquacious; and finding nothing would cure her, he put a pair of stays on her in order to take away her breath, and so prevent, as he thought, her talking. This cruel punishment was inflicted by other husbands, till at last there was scarcely a wife in all London who was not condemned to wear stays. The punishment became so universal at last that the ladies in their own defence made a fashion of it, and so it has continued to the present day. BERLIN GLOVES.—The custom of servants wearing Berlin gloves at dinner was introduced by Sir Jonas Bullock in 1811. He had a favourite black servant who used always to wait at dinner. The Lady Mayoress was dining with him one Sunday, and she had occasion to call for some blanc-mange. His black servant brought it to her, when his large black thumb by the side of the blanc-mange had such a shock upon her ladyship's feelings that she fainted away and was carried home to the Mansion House in a state of great danger. She never rallied. Sir Jonas was so hurt by this melancholy event that he insisted upon his servants for the future always wearing Berlin gloves when they waited at table; and from this the fashion was introduced at Devonshire House, and then at Court. MUFFINS.—We know very little of muffins previous to Johnson's time. They are supposed to have been invented by a Scotch physician, who was attached to the _suite_ of a German Count who came over with George I. He gave the recipe for nothing to a baker, on condition of his providing him with the address of all his customers. The bargain was faithfully carried out. The physician died extremely rich, and the baker also. Crumpets and Life Pills were likewise their invention.
