Mr. L. R. Breisach, to whom two patents were lately granted for ventilating chairs, has noticed that if any air be forced from bellows through tubes, electricity is developed. It is supposed that air so charged will be beneficial to nervous persons, and much easier of respi -ration by persons of weak lungs than the common atmosphere. We cannot see on what facts these suppositions are based, for if they be correct, persons living in a place where clouds that have swept over a mountain side, and that are full of electricity in a highly excited state, come in contact with them, should be very healthy indeed, instead of being, as they are, subject to epidemics and such diseases as goitre and the like.
