covering of the sarcophagus, weighs 45,000 kilograms (50 tons) ; its 

 extraction and carriage to Paris cost one hundred and forty thousand 

 francs ($28,000). It comes from the shores of Lake Onega. Be- 

 tween the tombs of Bertrand and Duroc a shrine will be erected to 

 receive the sword of Austerlitz, the imperial crown, and eighty 

 standards captured under the Empire. London Athenaum, March. 



SUBTERRANEAN MAP OF PARIS. 



A SUBTERRANEAN map of Paris, commenced in 1844, is, it is said, 

 nearly completed. It will form an atlas of forty-five sheets, cor- 

 responding to a superficies of five hundred by three hundred metres. 

 It will exhibit, quarter by quarter, all the labyrinthine sinuosities of 

 the ancient quarries and catacombs over which Paris is built, with the 

 corresponding edifices, squares, and streets above ground. The labors 

 of the engineers in the execution of this work have been, says the 

 Journal des Debats, of the most tedious and delicate nature. This may 

 be imagined, when it is understood that every subterranean point has 

 its corresponding exterior point, and that a double calculation is neces- 

 sary for the precise marshalling of objects without over the tortuous 

 lines (empty or encumbered) within. The map has been coordinat- 

 ed on the supposition of two axes ; one figuring a meridian passing 

 by the wall of the observatory, the other a line perpendicular to the 

 first. 



COMPARATIVE COST OF PUBLIC BUILDINGS.
