R., Ixxxiii., 1876.
The Physical Period 141 tion both of Mercury and Venus be about twenty-four hours, as seems probable, all the four planets nearest to the sun rotate in the same period, while the great planets rotate in about ten hours (Uranus and Neptune being still inde- terminate).
The general surface of Mars is a deep yellow; but there are dark grey or greenish patches.
Sir John Herschel was the first to attribute the ruddy colour of Mars to its soil rather than to its atmosphere.
The ob...servations of that keen-sighted observer Dawes led to the first good map of Mars, in 1869.
In the 1877 opposition Schiaparelli revived inter- est in the planet by the discovery of canals, uni- formly about sixty tniles wide, running generally on great circles, some of them being three or four thousand miles long. During the opposition of 1 88 1-2 the same observer re-observed the canals, and in twenty of them he found the canals dupli- cated,^ the second canal being always 200 to 400 miles distant from its fellow.
