FAILURE OF THE SUSPENSION BRIDGE AT PARIS. 



The suspension bridge erected over the Seine at Paris, opposite 

 the Hotel des Invalids, by M. Navier, Ingenieur des ponts^ et 

 chaussSes, has entirely failed; the attachments of the chams havmg 

 given way, on account of an error which it is conceived an engineer 

 of inferior mathematical attainment to M. Navier would readily 

 have avoided: and the circumstance is the more remarkable, as the 

 construction of the suspension bridges in England (none of which 

 has failed) has repeatedly been condemned by M. Navier.
