 circumstance attending this bridge, the Gothic arches 

 before spoken of, and in general all the arches of the 

 various galleries and apartments, that, as Mr. Smeath-

Consider what incredible labour and diligence, ac- 

 companied by the most unremitting activity and the 

 most unwearied celerity of movement, must be necessary 

 to enable these creatures to accomplish, their size consi-
