# In a Glass Darkly/Green Tea/Conclusion

CONCLUSION.
A WORD FOR THOSE WHO SUFFER.
MY dear Van L———, you have suffered from an affection similar to that which I have just described. You twice complained of a return of it.
Who, under God, cured you? Your humble servant, Martin Hesselius. Let me rather adopt the more emphasised piety of a certain good old French surgeon of three hundred years ago: "I treated, and God cured you."
​Come, my friend, you are not to be hippish. Let me tell you a fact.
I have met with, and treated, as my book shows, fifty-seven cases of this kind of vision, which I term indifferently "sublimated," "precocious," and "interior."
There is another class of affections which are truly termed—though commonly confounded with those which I describe—spectral illusions. These latter I look upon as being no less simply curable than a cold in the head or a trifling dyspepsia.
It is those which rank in the first category that test our promptitude of thought. Fifty-seven such cases have I encountered, neither more nor less. And in how many of these have I failed? In no one single instance.
There is no one affliction of mortality more easily and certainly reducible, with a little patience, and a rational confidence in the physician. With these simple conditions, ​I look upon the cure as absolutely certain.
You are to remember that I had not even commenced to treat Mr. Jennings' case. I have not any doubt that I should have cured him perfectly in eighteen months, or possibly it might have extended to two years. Some cases are very rapidly curable, others extremely tedious. Every intelligent physician who will give thought and diligence to the task, will effect a cure.
You know my tract on The Cardinal Functions of the Brain. I there, by the evidence of innumerable facts, prove, as I think, the high probability of a circulation arterial and venous in its mechanism, through the nerves. Of this system, thus considered, the brain is the heart. The fluid, which is propagated hence through one class of nerves, returns in an altered state through another, and the nature of that fluid is spiritual, though not immaterial, any more than, as I ​before remarked, light or electricity are so.
By various abuses, among which the habitual use of such agents as green tea is one, this fluid may be affected as to its quality, but it is more frequently disturbed as to equilibrium. This fluid being that which we have in common with spirits, a congestion found upon the masses of brain or nerve, connected with the interior sense, forms a surface unduly exposed, on which disembodied spirits may operate: communication is thus more or less effectually established. Between this brain circulation and the heart circulation there is an intimate sympathy. The seat, or rather the instrument of exterior vision, is the eye. The seat of interior vision is the nervous tissue and brain, immediately about and above the eyebrow. You remember how effectually I dissipated your pictures by the simple application of iced eau-de-cologne. Few cases, however, can be treated ​exactly alike with anything like rapid success. Cold acts powerfully as a repellant of the nervous fluid. Long enough continued it will even produce that permanent insensibility which we call numbness, and a little longer, muscular as well as sensational paralysis.
I have not, I repeat, the slightest doubt that I should have first dimmed and ultimately sealed that inner eye which Mr. Jennings had inadvertently opened. The same senses are opened in delirium tremens, and entirely shut up again when the over-action of the cerebral heart, and the prodigious nervous congestions that attend it, are terminated by a decided change in the state of the body. It is by acting steadily upon the body, by a simple process, that this result is produced—and inevitably produced—I have never yet failed.
Poor Mr. Jennings made away with himself. But that catastrophe was the result of ​a totally different malady, which, as it were, projected itself upon that disease which was established. His case was in the distinctive manner a complication, and the complaint under which he really succumbed, was hereditary suicidal mania. Poor Mr. Jennings I cannot call a patient of mine, for I had not even begun to treat his case, and he had not yet given me, I am convinced, his full and unreserved confidence. If the patient do not array himself on the side of the disease, his cure is certain.
