In a majority of the fatal cases of consumption, which I have seen, the passage out of life has been attended with pain; but I have seen many persons die with it, in whom all the above symptoms were so lenient, or so completely mitigated by opium, that death resembled a quiet transition from a waking, to a sleeping state. I cannot conclude this inquiry without adding, that the author of it derived from his paternal ancestors a predisposition to the pulmonary consumption, and that between the 18th and 43d years of his age, he has occasionally been afflicted with many of the symptoms of that disease which he has described. By the constant and faithful use of many of the remedies which he has recommended, he now, in the 61st year of his age, enjoys nearly an uninterrupted exemption from pulmonary complaints. In humble gratitude, therefore, to that BEING, who condescends to be called the preserver of men, he thus publicly devotes this result of his experience and inquiries to the benefit of such of his fellow-creatures as may be afflicted with the same disease, sincerely wishing that they may be as useful to them, as they have been to the author. OBSERVATIONS ON THE SYMPTOMS AND CURE OF _DROPSIES_. Whether we admit the exhaling and absorbing vessels to be affected in general dropsies by preternatural debility, palsy, or rupture, or by a retrograde motion of their fluids, it is certain that their exhaling and absorbing power is materially affected by too much, or too little action in the arterial system. That too little action in the arteries should favour dropsical effusions, has been long observed; but it has been less obvious, that the same effusions are sometimes promoted, and their absorption prevented, by too much action in these vessels. That this fact should have escaped our notice is the more remarkable, considering how long we have been accustomed to seeing serous swellings in the joints in the acute rheumatism, and copious, but partial effusions of water in the form of sweat, in every species of inflammatory fever. It is nothing new that the healthy action of one part, should depend upon the healthy action of another part of the system. We see it in many of the diseases of the nerves and brain. The tetanus is cured by exciting a tone in the arterial system; madness is cured by lessening the action of the arteries by copious blood-letting; and epilepsy and hysteria are often mitigated by the moderate use of the same remedy.
