the Incas, without recognising the same type in 

 all the others that cover the ridge. of the Andes., 

 on an extent of more than four hundred and fifty 

 leagues, from a thousand to four thousand metres 

 above the level of the ocean. It might be said, 

 that a single architect constructed this great 

 number of monuments, so strictly were this peo- 

 ple of mountaineers attached to their domestic 

 habits, their civil and religious institutions, and 

 the form and distribution of their buildings. It 

 will be easy in some future day to ascertain from 

 the drawings contained in this work, whether 

 buildings exist in Upper Canada, as the learned 

 author of the Noticias Americanas asserts, which 

 in the cut of their stones, the form of their doors 

 and small niches, and the distribution of their 

 apartments, display traces of the Peruvian style ; 

 and this inquiry is so much the more interesting 

 to those, who devote themselves to historical re- 

 searches, as we know from sure testimony, that 

 the Incas built the fortress of Cuzco after the 

 model of the most ancient edifices of Tiahuana- 

 co, situate in 17° 12' south latitude. 



The stone made use of for the house of Hu- 

 ayna-Capac, mentioned by Cie9a* under the 

 name of aposentos de Mulahalo, is a rock of 

 volcanic origin, a burnt and spongy porphyry 

 with basaltic basis. It was probably ejected by 



* Chronica del Peru, cap. 41 (cd. de 1554, p. 108).
