Preliminary Notices of Some of the More Interesting Exhibits.
,r, HE DISPLAY of accessories and components suitable for employment on and attachment to commercial-motor chassis and vehicles, will, when the doom of Olympia open to the public on Friday, 15th instant, prove to be more extensive than has ever been possible in any previous exhibition with similar aims.
