Recommends that the arch should hegin at high water 

 mark : remarks, that the breadth of the piers may be made 

 much less than one fifth of that of the arches. 



Perronet is sometimes too ostentatious of art, but his 

 bridge at Orleans is a masterpiece ; the bridge at Neuilly 

 can scarcely stand long. Robison.

Observes, that in the plates bandes, or flat arches, over 

 windows, the planes of the joints should converge to a 

 single axis; and that the stones will fall unless the perpen- 

 dicular to the lowest point of the abutment meet the verti- 

 cal, passing through the centre of gravity of the half arch, 

 within its substance. This may be easily understood by 

 considering the arch as composed of two pieces.
