Reuters quote of the day, July 23

London, July 22 (Reuters) Following is a notable quote from history. ''I am leaving the regions of fact, which are difficult to penetrate, but which bring in their train rich rewards, and entering the regions of speculation, where many roads lie open, but where a few lead to a definite goal.'' -- Sir William Ramsay, Scottish chemist, in his Nobel Prize acceptance speech. Ramsay, who discovered helium, argon and other inert gases, died on July 23, 1916.
