The Recent Meteor
     Below we give a letter from Prof. Leonard of the State University, at Iowa City, giving a short description of the fireball as it appeared to observers there, and asking for full descriptions by those who saw it from other points:
            IOWA STATE UNIVERSITY
            CHAIR MATHEMATICS AND ASTRONOMY,
            N.R. LEONARD, Professor.
            IOWA CITY, February 13, 1875

    Editor of the State Register:- A very large and brilliant fireball passed this city last evening at 10:30 Chicago time. Its size apparently half that of the full moon, its course slightly north of west. The fire-ball was accompanied by a broad train of light. The color of the ball was compared to that of molton iron, and its train slightly tinged with green. There were three separate explosions of the fireball while it was in view, and after an interval of two or three minutes after its disappearance a report, which those who were indoors compared to the noise of a train of cars, and those outside noticed something resembling three discharges of blasts in the quarry. The concussion seems to have been more violent to the west of us, and I entertain hopes that some fragments of the meteorite will be found within the limits of our State. I shall feel greatly obliged to any of our readers who will furnish me an account of any observations they may have made of this meteor.
            Very truly yours,        N.R. LEONARD.
