Mr. Douglas, not confining comparison to London, compares the temperature of Pau with that also of other places in Great Britain, showing that the sunny temperature of Pau is 4°·1 below that of Helstone in Cornwall, and is under that of Torquay in Devonshire and Valentia in Ireland during the same winter months, and quotes Dr. Otley to the effect that there is greater daily range of temperature at Pau than in England, adding that the nights must be colder at Pau than in the west coasts of Britain, and expresses the opinion that ‘no one who cannot stand severe cold ought to think of going to Pau for the winter; better go to Easdale in Argyllshire. No one so constituted should think of going till March at soonest; April, in my opinion, is early enough.’ Mr. Douglas writes as a meteorologist, and his little volume is a valuable contribution to the consideration of the temperature of the various places of health resort therein mentioned; but the facts stated by Dr. Taylor, even though one is inclined to look with suspicion on medical advocates of special places, show that the value of a place for an invalid may not wholly depend on the records of the thermometer. * * * * * We made Pau only a halting–place for nine days, _en route_ for the Riviera, and to form some opinion as to its suitability for a longer stay at another time. Coming from the ever–changing ocean, and from Biarritz, which had so captivated our fancy, perhaps we did not take so kindly to Pau, a large inland rural town, as we might otherwise have done; while, in consequence of the season not having fairly commenced, the strangers encountered in the streets were few, and the town consequently was more dull than it would have been later on. The weather also was such that we had not much opportunity of seeing the environs. * * * * * Before 1840, Pau apparently was a place of no repute. I presume Dr. Taylor’s recommendation gave it its great stimulus. But in twenty years after 1840 it had largely increased, evidences of which were, that the octroi duty had in 1860 realized nearly double, that the British visitors had amounted to 1000 in number in the year, and that its population had augmented to 21,000. It has gone on increasing since, and is now so well frequented as to require no less than three English churches and one Scotch church, with resident ministers, while the population is reckoned to amount to 30,000.
