At Frankfort and Heidelberg, however, the mean temper-ature for the entire year is, aecording to the table publisliedby the same eminent authority, 49° 5' respectively; and thatfor the winter months as low as between 33° and 34°, whilstfor the summer it seems to be, after a long series of observations,only a fraction above 64°.* Hence it will be pereeived, that

Cherbourg andIreland show in the most remarkable manner how, with thermal relations verynearly similar to those prevailing in the interior of the Continent, the results arenevertheless extremely different as regards the ripeness orunripeness of the fruit."

The above table proves that the produetion of " potable wine" does notdepend on latitude; since Cherbourg, whose latitude is only 49° 39', does notproduce wine, whilst Frankfort does, thougli its latitude is but 50° 7'. Coblenz,again, is about the latitude of Plymouth, 50° 22', whilst Mayence is nearlyupon the parallel of the Lizard in Comwall, 49° 57'; and all the best wines ofGermany are grown between these places — that is to say, either on the Rhine orits tributary rivers. None of the better wines of France, however, are grown sofar north.
Nor does the produetion of a potable wine depend on the mean annual tem-
