 of construction, which on the banks of the Eu- 

 phrates and the Tigris may be traced back to 

 the remotest antiquity. 



The porphyry made use of for the buildings of 

 Cannar is cut into parallelopipedons with such 

 perfection, that the joints of the stone would be 

 imperceptible, as M. de la Condamine remarks, 

 if their exterior surface were a plane ; but the 

 outer surface of each stone is slightly convex, 

 and cut slantingly towards the edge ; so that the 

 joints form small flirtings, which serve as orna- 

 ments, like the separations of the stones in rustic 

 work. This cut of the stone, which the Italian 

 architects call bugnato, is found in the ruins of 

 Callo, near Mulado, where I have sketched it in 

 detail | : it gives the walls of the Peruvian build-
