a sphere 80 or 100 miles in diameter, and there is perhaps 
no occasion for surprise that the results of the collision of a 
body of such magnitude were exceptional in character as 
well as extent. 
So far as I am aware, these features of sculpture have not 
previously been recognized.* It is therefore of special im¬ 
portance that my observations be verified by those of others,

great furrows by heavy lines. Irregular lines show crests of uplands surroundipg

and to this end the general statement will be supplemented 
by the enumeration of enough particulars to serve as a clue 
to the recognition of the novel phenomena. The general 
distribution of the sculpture, comprising the districts in 
which it is faintly exhibited as well as those in which it is 
conspicuous, is indicated in Fig. 14, where the shaded areas
