ing correction needed in all the other mountains 

 delineated. 1 



The whole map is exceedingly minute, and the 

 localities mostly correctly named, but there are 

 some errors of position, both absolute and relative, 

 such that I suppose the map to have been con- 

 structed mainly from a simple view of the country, 

 and that no angles and very few compass-bearings 

 have been taken. The margins of the map corre- 

 spond so nearly with the actual parallels and 

 meridians, that they may be assumed to represent 

 the cardinal points of the compass, as on an 

 ordinary map, without sensible error. 



The country represented extends from Cotopaxi 

 on the north to the base of Tunguragua on the 

 south, and from the plain of Callo (at the western 

 foot of Cotopaxi) on the west to the river Puyu, in 

 the forest of Canelos, on the east. It includes an 

 area of something less than an equatorial degree, 

 namely, that comprised between o 40' and i 33' 

 S. lat., and between o 10' \V., and near o c 50' E. 

 of the meridian of Quito. In this space are re- 

 presented six active volcanoes (besides Cotopaxi), 

 viz.- 



i. El Volcan cle los Mulatos, east a little south 

 from Cotopaxi, and nearly on the meridian of the 

 Rio cle Ulva, which runs from Tunguragua into the 

 Pastasa. The position of this volcano corresponds 

 to the Quilindana of most maps a name which 

 does not occur on Guzman's, nor is it known to any 

 of the actual residents of the country. A group of 

 mountains running to north-east, and terminating in 



1 The apical angle of Tunguragua the steepest mountain I ever chinlied 

 is 92.J, , and tlir slope 43} .
