PERTH BRIDGE,

HE most beautiful structure of the kind in North-Britain, was defigned and executed by Mr Smeton. Its length is nine hundred feet; the breadth (the only blemish) twenty-two within the parapets. The piers are founded ten feet beneath the bed of the river, upon oaken and beechen piles, and the ftones laid in puzzalane, and cramped with iron. The number of arches nine; of which the centre is feventy-five feet in diameter. This noble work opens a communication with all the different great roads of the kingdom, and was completed at the expence of twenty-fix thousand pounds: of this the commiffioners of forfeited eftates, by his Majefty's permiffion, gave eleven thousand; Perth two; private fubfcribers, four thoufand feven hundred and fifty-fix the royal boroughs, five hundred. But ftill this great work would have met with a check for want of money, had not the Earl of Kinnoul, with his characteristic public fpirit, advanced the remaining fum, and taken the fecurity of the tolls, with the hazard only to himself.

Gowrie houfe was formerly the property and refidence of the Earl of Gowrie, whose tragical end and myfterious confpiracy (if conspiracy there was) are still fresh in the minds of the people of Perth. At prefent the house is occupied by fome companies of artillery. The staircase is ftill fhewn where the unhappy nobleman was killed, the window the frightened monarch James roared out bf, and that he escaped through when he was faved from the fury of the populace.

As it is a record of facts or obfervations, and a fyftem founded on them, every perfon may judge for himself how fat the former corroborate the Doctor's theory or overturn it, and whether the author's conclufions are valid or other wife.

but he has collected fixty fpecimens of fuch as it is most important to be acquainted with. Thefe are fold with his book, and the price of the whole in France is 36 livres. Of the fpecimens, each of which is about half a pound weight, fourteen are from primary mountains, twenty-feven are ftones that have been formed by the waters, fourteen are volcanic, and five are as it were in the very moment of their formation.

In treating of ftratified, or fecondary mountains, the author goes back to the time when none but primary mountains exifted, their bafe buried in the abyfs of the fea, and their tops only Ggz

M. Voigt has not only given a methodical and inftructive defcription of all thofe fofils that generally compose the interior parts of mountains,
