Note 52 — THE LAKE DIALECT.

I mean that they included the progressive or outward-bound course, and equally the regressive or homeward-bound course, within the compass of this one word διαυλος. We in England have a phrase which conventionally has been made to supply the want of such an idea, but unfortunately with a limitation to the service of the Post-office. It is the phrase course of post. When a Newcastle man is asked, 'What is the course of post between you and Liverpool?' he understands, and by a legal decision it has been settled that he is under an obligation to understand—What is the diaulos, what is the flux and reflux—the to and the fro—the systole and diastole of the respiration—between you and Liverpool. What is the number of hours and minutes required for the transit of a letter from Newcastle to Liverpool, but coupled with the return transit of the answer? This forward and backward movement constitutes the diaulos: less than this will not satisfy the law as the complex process understood by the course of post. Less than this is only the half section of a diaulos.
