REVIEWS—NELSON’S ATLAS, AND WALL AND FAMILY MAPS. 55 
readily intelligible, and more suited for general use. From this have 
resulted the following new and distinctive features:—Ist. All the 
maps, with the exception of the hemispheres, are laid off in squares 
of a specific number of one thousand miles, and these are again sub- 
divided into squares of one hundred miles each. For example, the 
map of Europe forms a square of four thousand English miles, subdi- 
vided into smaller measured squares; and the map of England em- 
braces a square of four hundred miles. sub-divided into squares of one 
hundred miles. In ordinary atlases the scale varies so much, that 
the young student is in danger of adopting the impression that Eng-- 
land is about the same size as Russia, or the United States. In the new 
atlas this is effectually obviated. Russia, and Norway and Sweden, 
as the largest countries of Europe, exceeding in area one thousand: 
square miles, are laid off on maps of the definite number of measured’ 
squares. All the other countries of Europe, and also the Canadas, 
Cape Colony, New South Wales, &c., are mapped on the standard 
seale of one thousand miles square. Hach map moreover, embraces 
all within the measured area, so that the student has always the rela- 
tive size and distances brought vividly to his mind; and the compara- 
tive extent of separate countries cannot be over-looked. 
By this simple process, the youngest child can ascertain at once 
how far Edinburgh is from London, or Toronto from Quebec. By 
the old process, the student would ascertain that Quebec is in latitude 
46 degrees, 49 minutes, North; longitude 71 degrees, 16 minutes, 
West ; by the New Atlas, in addition to this he ascertains at a glance 
that it is about 3,050 miles west of London; about 320 miles south 
of London ; and 3,330 north of the equator. He can also ascertain with 
ease its approximate distance from any desired point. Thus by the 
maps, with the additional assistance of a copious index and table of 
distances, the student has at his command relative geographical posi- 
tions in this form: Rome, for example, lies 540 miles east of London, 
and 663 miles south of it. Its direct distance is 889 miles. 
The maps retain the ordinary degrees of latitude and longitude, so 
that whatever novel features they present are additions, not substitutes 
for the old system and terms of measurement. But on the hemi- 
spheres the lines of latitude are drawn at intervals of 1000 miles north 
and south of London, and the lines of longitude at the same intervals 
measured on the parallel of London. In addition to those, another 
class of circles drawn from London as a centre, show the distance by 
thousands of miles from that point ; and on the other maps the lines
