12. Are there any advantages to be derived from the excitement of certain PASSIONS in the treatment of consumptions? Dr. Blane tells us, that many consumptive persons were relieved, and that some recovered, in consequence of the terror which was excited by a hurricane in Barbadoes, in the year 1780. It will be difficult to imitate, by artificial means, the accidental cures which are recorded by Dr. Blane; but we learn enough from them to inspire the invigorating passions of hope and confidence in the minds of our patients, and to recommend to them such exercises as produce exertions of body and mind analogous to those which are produced by terror. Van Sweiten and Smollet relate cures of consumptions, by patients falling into streams of cold water. Perhaps, in both instances, the cures were performed only by the fright and consequent exertion produced by the fall. This is only one instance out of many which might be mentioned, of partial and unequal action being suddenly changed into general and equal excitement in every part of the system. The cures of consumptions which have been performed by a camp life[29], have probably been much assisted by the commotions in the passions which were excited by the various and changing events of war.

13. A SALIVATION has lately been prescribed in this disease with success. An accident first suggested its advantages, in the Pennsylvania hospital, in the year 1800[30]. Since that time, it has performed many cures in different parts of the United States. It is to be lamented, that in a majority of the cases in which the mercury has been given, it has failed of exciting a salivation. Where it affects the mouth, it generally succeeds in recent cases, which is more than can be said of any, or of all other remedies in this disease. In its hectic state, a salivation frequently cures, and even in its typhus and last stage, I have more than once prescribed it with success. The same regard to the pulse should regulate the use of this new remedy in consumption, that has been recommended in other febrile diseases. It should never be advised until the inflammatory diathesis of the system has been in a great degree reduced, by the depleting remedies formerly mentioned.

During the use of the above remedies, great care should be taken to relieve the patient from the influence of all those debilitating and irritating causes which induced the disease. I shall say elsewhere that decayed teeth are one of them. These should be extracted where there is reason to suspect they have produced, or that they increase the disease.

I have hitherto said nothing of the digitalis as a palliative remedy in pulmonary consumption. I am sorry to acknowledge that, in many cases in which I have prescribed it, it has done no good, and in some it has done harm. From the opposite accounts of physicians of the most respectable characters of the effects of this medicine, I have been inclined to ascribe its different issues, to a difference in the soil in which it has been cultivated, or in the times of gathering, or in the manner of preparing it, all of which we know influence the qualities of many other vegetables. If the theory of consumption which I have endeavoured to establish be admitted, that uncertain and unsafe medicine will be rendered unnecessary by the remedies that have been enumerated, provided they are administered at the times, and in the manner that has been recommended.

Before I proceed to speak of the radical cure of the consumption, it will be necessary to observe, that by means of the palliative remedies which have been mentioned, many persons have been recovered, and some have had their lives prolonged by them for many years; but in most of these cases I have found, upon inquiry, that the disease recurred as soon as the patient left off the use of his remedies, unless they were followed by necessary or voluntary exercise.

It is truly surprising to observe how long some persons have lived who have been affected by a consumptive diathesis, and by frequent attacks of many of the most troublesome symptoms of this disease. Van Sweiten mentions the case of a man, who had lived thirty years in this state. Morton relates the history of a man, in whom the symptoms of consumption appeared with but little variation or abatement from his early youth till the 70th year of his age. The widow of the celebrated Senac lived to be 84 years of age, thirty of which she passed in a pulmonary consumption. Dr. Nicols was subject to occasional attacks of this disease during his whole life, and he lived to be above eighty years of age. Bennet says he knew an instance in which it continued above sixty years. I prescribed for my first pupil, Dr. Edwards, in a consumption in the year 1769. He lived until 1802, and seldom passed a year without spitting blood, nor a week without a cough, during that long interval of time. The fatal tendency of his disease was constantly opposed by occasional blood-letting, rural exercises, a cordial, but temperate diet, the Peruvian bark, two sea voyages, and travelling in foreign countries. There are besides these instances of long protracted consumptions, cases of it which appear in childhood, and continue for many years. I have seldom known them prove fatal under puberty.

I am led here to mention another instance of the analogy between pneumony and the pulmonary consumption. We often see the same frequency of recurrence of both diseases in habits which are predisposed to them. I have attended a German citizen of Philadelphia, in several fits of the pneumony, who has been confined to his bed eight-and-twenty times, by the same disease, in the course of the same number of years. He has, for the most part, enjoyed good health in the intervals of those attacks, and always appeared, till lately, to possess a good constitution. In the cases of the frequent recurrence of pneumony, no one has suspected the disease to have originated exclusively in a morbid state of the lungs; on the contrary, it appears evidently to be produced by the sudden influence of the same causes, which, by acting with less force, and for a longer time, produce the pulmonary consumption. The name of pneumony is taken from the principal symptom of this disease, but it as certainly belongs to the whole arterial system as the consumption; and I add further, that it is as certainly produced by general predisposing debility. The hardness and fulness of the pulse do not militate against this assertion, for they are altogether the effects of a morbid and convulsive excitement of the sanguiferous system. The strength manifested by the pulse is moreover partial, for every other part of the body discovers, at the same time, signs of extreme debility.

It would be easy, by pursuing this subject a little further, to mention a number of facts which, by the aid of principles in physiology and pathology, which are universally admitted, would open to us a new theory of fevers, but this would lead us too far from the subject before us. I shall only remark, that all that has been said of the influence of general debilitating causes upon the lungs, both in pneumony and consumption, and of the alternation of the consumption with other general diseases, will receive great support from considering the lungs only as a part of the whole external surface of the body, upon which most of the remote and exciting causes of both diseases produce their first effects. This extent of the surface of the body, not only to the lungs, but to the alimentary canal, was first taken notice of by Dr. Boerhaave; but was unhappily neglected by him in his theories of the diseases of the lungs and bowels. Dr. Keil supposes that the lungs, from the peculiar structure of the bronchial vessels, and air vesicles, expose a surface to the action of the air, equal to the extent of the whole external and visible surface of the body.

Thus have I mentioned the usual palliative remedies for the consumption. Many of these remedies, under certain circumstances, I have said have cured the disease, but I suspect that most of these cures have taken place only when the disease has partaken of an intermediate nature between a pneumony and a true pulmonary consumption. Such connecting shades, appear between the extreme points of many other diseases. In a former essay[31], I endeavoured to account for the transmutation (if I may be allowed the expression) of the pneumony into the consumption, by ascribing it to the increase of the debilitating refinements of civilized life. This opinion has derived constant support from every observation I have made connected with this subject, since its first publication, in the year 1772.

I come now to treat of the RADICAL REMEDIES for the pulmonary consumption.
