Is there any evidence that human beings can be infected or wrought upon by poisons, or otherwise, so that they shall manifest any of the peculiarities belonging to beings of a lower nature? Can such peculiarities--be transmitted by inheritance? Is there anything to countenance the stories, long and widely current, about the “evil eye”? or is it a mere fancy that such a power belongs to any human being? Have you any personal experience as to the power of fascination said to be exercised by certain animals? What can you make of those circumstantial statements we have seen in the papers, of children forming mysterious friendships with ophidians of different species, sharing their food with them, and seeming to be under some subtile influence exercised by those creatures? Have you read, critically, Coleridge's poem of “Christabel,” and Keats's “Lamia”?--If so, can you understand them, or find any physiological foundation for the story of either? There is another set of questions of a different nature I should like to ask, but it is hardly fair to put so many on a single sheet. There is one, however, you must answer. Do you think there may be predispositions, inherited or ingrafted, but at any rate constitutional, which shall take out certain apparently voluntary determinations from the control of the will, and leave them as free from moral responsibility as the instincts of the lower animals? Do you not think there may be a crime which is not a sin? Pardon me, my dear Sir, for troubling you with such a list of notes of interrogation. There are some very strange things going on here in this place, country-town as it is. Country-life is apt to be dull; but when it once gets going, it beats the city hollow, because it gives its whole mind to what it is about. These rural sinners make terrible work with the middle of the Decalogue, when they get started. However, I hope I shall live through my year's school-keeping without catastrophes, though there are queer doings about me which puzzle me and might scare some people. If anything should happen, you will be one of the first to hear of it, no doubt. But I trust not to help out the editors of the “Rockland Weekly Universe” with an obituary of the late lamented, who signed himself in life-- Your friend and pupil, BERNARD C. LANGDON. The Professor to Mr. Langdon.
