Africa. Prussia. Maps by Keith Johnston, F.R.S.E. (Blackwood.) —Two plates

from Mr. Keith Johnston's excellent " General Atlas,' the first on a scale of 300, the second of 32, miles to an inch. This, no doubt, is significant of the tenfold greater importance of Prussia than Africa at the present day, but the result is that the parts of Africa .which are inhabited seem much more crowded than the whole of Prussia. Geography is apt to mislead us when we forget the vast difference pro- duced by the change from one scale to another, and we think that places are separated by only a few inches until we are reminded, as by the black in Captain Marryatt's novel, that they are "berry long inches."
