28 JANUARY 1865, Page 2

London was visited this day week by one of the

densest fogs seen for years. It was impossible at 11 p.m. even to see the side lamps, the roads were as slippery as glass, and locomotion almost ceased. The accidents were numerous, and but that the thieves were as puzzled as the police and the people the outrages would have been frequent too. The fog was remarkable, too, for its hardness of out- line. In Park Street, North London, at 11 p.m., you drove into it as into a gate. A writer in the Times argues with great force that these fogs rise from the undrained land round and about Harrow, land so marshy that agae is hardly extinct at Edgware, and sheep get the foot-rot. The exhalation from this district rolls into Lon- don and mixes with the smoke till it produces the phenomenon described in Scripture as " darkness which can be felt."
