Dr. Blank--Persons addicted to the constant use of these so-called poisons, gradually become abnormal. The atoms composing their organisms have, so to say, become saturated to a degree that will not admit of the further entertainment of the qualities offered. Just as a fully-saturated sponge, though plunged into an ocean, would reject another drop of water. We have drifted somewhat apart from our starting point, and I regret to perceive that the lesson has disturbed your serenity, but I feel assured that you desire that humanity may come to realize that in all things cause and effect go hand in hand. That both in and apart from the physical body, all are their own jury and judge. That mortal life is the preparatory school in which all learn their lessons well or ill, and that on the spirit, as on the physical side, _the school of experience knows no vacation_. From what I have said you will understand that the effects of some so termed poisons are far reaching. I may add that every emotion of the mind, food, drink, the dyes in textile fabrics, especially for clothing, in fact the atoms composing all substances, more or less affect the physical, consequently the spiritualized soul body. In some persons a certain color or colors produces either exhilaration or depression. They may not be conscious of the cause, though very conscious of the effect. Your strong dislike for wholly black garments is an indication that you should not wear them. _Sensitives never should wear colors darker than the red corpuscles of their blood._ Azure blue, yellow, rose red, very light shades of purple and a certain light shade of green are the colors suited to your temperament. Always, advantageously, you may wear white. I simply have touched upon some points which, with your and your friends' permission, I may at another time elaborate. In chemistry I am well enough versed to perceive that this is a splendidly equipped laboratory and I learn from his remarks that the stately Professor is a competent Instructor. During my mortal existence I regarded myself, and was considered, an authority in the science of chemistry, but I have learned that, compared with Ento chemists, I was a mere tyro. They, through a larger knowledge of the wondrous science, have made of the elements tractable servants whose energies are tireless; whose adaptability is limitless. Madame, the allotted hour has quickly flown. My promise to our mutual friend is fulfilled and with measureless hopes and fervent wishes for the success of your most worthy efforts on behalf of the mission, I must bid you and these friends adieu. Gentola--Adieu, and believe that I greatly appreciate the thoughtful kindness of our mutual friend, at whose request you have afforded me another strange and useful lesson.
