The accompanying map is used for the illustration of this work by permission of the council of the Royal Geographical Society. The original compilation and drawing has been made on a scale of 1:1,000,000 in four sheets; but for the purpose of publication the map has been reduced to a scale of 1:2,000,000. The map extends from 8° to 18° S. and from 65° to 74° W., the area included being about 418,000 square miles. No regular surveys exist of the region as a whole, nor are any likely to be undertaken for years to come. Consequently, for the greater part of it, the mapping has depended upon route traverses varying considerably in merit, but fairly good in cases where astronomical observations have been taken.

The compilation and drawing has taken two years, and has necessitated comparing and determining the value of a large amount of cartographical material and many observations.

About sixty observed positions for latitude and twenty for longitude have been accepted, and the materials used include thirty-two recent maps and
