That diet, which most imparts vital power to the blood, and through it to the entire system, must always be preferred in pulmonary cases. By invigorating, we do not mean stimulating food—the object being to strengthen and build up; not to stimulate, and occasion an ultimate reaction, with debility—but permanently to create power. A vegetable diet yields nourishing properties to some, but, in a majority of instances, it is inadequate for the purposes of producing the required nutrition: on the contrary, animal diet partaken with a due regard to the circumstances of the case, always adapting the quantity and quality to the power of digestion, and peculiarities of constitution, so as to prevent fever and disorder, increases the power of the digestive functions, enriches the vital fluid—the blood, and gives tone and vigour to the system. Frequent changes of air and scene will be found extremely beneficial, both in a physical and mental point of view. The sea air is, of all others, the purest—and on that account, better calculated generally, for the purposes of breathing, in weakly persons. In all air there is more or less of that principle which is essential to life; but the air which passes over an extensive tract of water is not only refrigerated or cooled, but purified; and consequently, the bad effects of the sultry heats of the summer season are counteracted. A temporary sojournment at the sea-side, for the purpose of inhaling the saline particles, with which the sea breezes are impregnated, with occasional excursions on the ocean, or short voyages by sea, will be attended with much advantage, as a means for stimulating the lungs to deeper and more frequent inspiration, and tending to enlarge the cavity of the chest, a matter of great importance. These means will be found highly serviceable, and an excellent auxiliary to the use of the Balsam herein recommended, as possessing a true tonic power, which will brace and invigorate the surface of the body, and exert a beneficial influence on the viscera, especially those connected with the digestive functions. It must, however, be observed, that there are some consumptive patients, with whom sea air never agrees—when country air, especially in the rural agricultural districts, must be substituted. Exercise is generally beneficial when the degree is proportionate to the strength of the patient, without producing fatigue, and in a pure atmosphere, remote from large cities or towns, in situations not exposed to winds, especially the north-east. The exercise should be in the open air on horseback, the greater part of the day, in fine weather—if the strength will permit; and a nourishing diet of new milk, farinaceous preparations, animal soups, and solid animal food twice a day. The bowels to be gently relieved every second or third day, and the cough mixture—the Balsam, to be continued as before directed.
