_Mr. B._ But cannot this objection be obviated by suitable cloathing? _Dr. A._ To a certain extent perhaps, but recollect if you please, that there is no furnishing a great coat for the lungs, to protect their structure against the diminished temperature of the air which is breathed. _Mr. B._ What opinion have you formed respecting the effects of a marine atmosphere? _Dr. A._ I apprehend that question cannot be fairly answered without a reference to the symptoms and circumstances of each particular case; generally speaking, I am induced to consider the air of the sea as not hostile to diseased lungs, except perhaps in those cases in which Hectic fever is fully established; but then again cases will sometimes occur which would appear to sanction a contrary conclusion. Thus much I should say was certainly true, that in such situations you will always experience more humidity, and that when the air is cold, that cold will in consequence be more intolerable, for the reasons I have before stated. On the other hand you must be aware that a marine situation will enjoy a more equable temperature[138] than one similarly situated, but remote from the ocean, and as far as that goes it will have its advantages. _Mr. B._ I should much like to know what the continental physicians think of this circumstance, with reference to their own climate. _Dr. A._ Upon that point you may be easily satisfied by referring to Dr. Clark's work on foreign climates.[139] He says that the physicians on the sea coast send their consumptive patients into the interior, and those in the interior to the shores of the Mediterranean or Adriatic. From Genoa they send them into the interior, deeming the sea air injurious to them. From Naples they frequently send such invalids to Rome. From Rome, on the other hand, they send them frequently to Cività Vecchia, on the shores of the Mediterranean; more frequently to the shores of the Adriatic, and, occasionally, even to Naples! _Mr. B._ And is this account to _satisfy_ me? why I am plunged deeper in doubt than ever by such testimony. No wonder that the physician should approach the subject of Climate with diffidence when he finds those best able, from experience, to appreciate its merits, so irreconcileably at variance with each other. In the next place, let me ask whether you advocate the advantages of a Sea Voyage? _Dr. A._ Not unconditionally. Dr. Young has said, and I believe with much truth, that the greatest possible equability of temperature is to be obtained in a sea voyage to a warm climate; in which the variation will seldom amount to half as much as in the most favourable situation on shore, even on a small island. _Mr. B._ The very condition which, of all others, you consider the most beneficial.
