4. If fair weather continue for several days, during which the mercury continually falls, a long continuance of foul weather will probably ensue; and again, if foul weather continue for several days, while the mercury continually rises, it long succession of fair weather will probably succeed. 5. A fluctuating and unsettled state in the mercurial column indicates changeable weather. The domestic barometer would become a much more useful instrument, if, instead of the words usually engraved on the plate, a short list of the best established rules, such as the above, accompanied it, which might be either engraved on the plate, or printed on a card. It would be right, however, to express the rules only with that degree of probability which observation of past phenomena has justified. There is no rule respecting these effects which will hold good with perfect certainty in every case. This volume, we should add, is by Dr. Lardner, the editor of the _Cyclopædia_, and is a good model for his collaborateurs. * * * * * REFLECTION. It is better to reflect ourselves, than to suffer others to reflect for us. A philosopher has a system; he views things according to his theory; he is unavoidably partial; and, like Lucian's painter, he paints his one-eyed princes in profile. * * * * * [Illustration: STATUE OF PETER THE GREAT.] This superb work of modern art stands in one of the finest squares of St. Petersburgh, and of Europe, according to Sir Robert Ker Porter. It was erected by command of the Empress Catherine, and, like all her projects, bears the stamp of greatness. The name of the artist is Falconet: "he was a Frenchman; but," adds Sir R.K.P. "this statue, for genius and exquisite execution, would have done honour to the best sculptors of any nation. A most sublime conception is displayed in the design. The allegory is finely imagined; and had he not sacrificed the result of the whole to the prominence of his group, the grand and united effect of the statue and its pedestal striking at once upon the eye, would have been unequalled in the works of man. A mass of granite, of a size at present most immense, but formerly most astonishing, is the pedestal. A steep acclivity, like that of a rugged mountain, carries the eye to its summit, which looks down on the opposite side to a descent nearly perpendicular. The figure of the hero is on horseback, supposed to have attained the object of his ambition, by surmounting all the apparent impossibilities which so arduous an enterprise presented. The victorious animal is proudly rearing on the highest point of the rock, whilst his imperial master stretches forth his mighty arm, as the father and protector of his country. A serpent, in attempting to impede his course, is trampled on by the feet of the horse, and writhing in all the agonies of expiring nature. The Emperor is seated
