Much has been said in favour of sea voyages in consumptions. In the mild degrees of the disease they certainly have done service, but I suspect the relief given, or the cures performed by them, should be confined chiefly to seafaring people, who add to the benefits of a constant change of pure air, a share of the invigorating exercises of navigating the ship. I have frequently heard of consumptive patients reviving at sea, probably from the transient effects of sea sickness upon the whole system, and growing worse as soon as they came near the end of their voyage. It would seem as if the mixture of land and sea airs was hurtful to the lungs, in every situation and condition in which it could be applied to them. Nor are the peculiar and morbid effects of the first operation of land and sea airs upon the human body, in sea voyages, confined only to consumptive people. I crossed the Atlantic ocean, in the year 1766, with a sea captain, who announced to his passengers the agreeable news that we were near the British coast, before any discovery had been made of our situation by sounding, or by a change in the colour of the water. Upon asking him upon what he founded his opinion, he said, that he had been sneezing, which, he added, was the sign of an approaching cold, and that, in the course of upwards of twenty years, he had never made the land (to use the seaman's phrase) without being affected in a similar manner. I have visited many sick people in Philadelphia, soon after their arrival from sea, who have informed me, that they had enjoyed good health during the greatest part of their voyage, and that they had contracted their indispositions after they came within sight of the land. I mention these facts only to show the necessity of advising consumptive patients, who undertake a sea voyage for the recovery of their health, not to expose themselves upon deck in the morning and at night, after they arrive within the region in which the mixture of the land and sea airs may be supposed to take place. I subscribe, from what I have observed, to the bold declaration of Dr. Sydenham, in favour of the efficacy of riding on horseback, in the cure of consumption. I do not think the existence of an abscess, when broken, or even tubercles in the lungs, when recent, or of a moderate size, the least objection to the use of this excellent remedy. An abscess in the lungs is not necessarily fatal, and tubercles have no malignity in them which should render their removal impracticable by this species of exercise. The first question, therefore, to be asked by a physician who visits a patient in this disease should be, not what is the state of his lungs, but, is he able to ride on horseback.
