DETROIT, Mich., Monday, Aug. 16, 1875.
  Prof. N. R. Leonard, of the State University at Iowa City, Iowa, gave the following description of the path of a meteorite seen in Iowa County, exhibiting, also, a fragment of it. This meteorite appeared on Feb. 12, 1875, about 10:15 P.M., passing from south-west to north-east. Its own brilliancy, and a very clear sky, caused it to be seen 450 miles from south-west to north-east, and 250 miles from east to west. The meteor appeared to change somewhat its shape, being first described as an oblong, with a smooth front and streaming sparks and train behind, afterward assuming the form of an elongated horse-shoe with the closed end to the front. In this latter form it seemed to have a sort of flowing jacket of flame, between which and the brilliant core, or central part, there was a very narrow dark space. The meteor changed its color as it approached the earth, passing through the different shades, from white to red, when it disappeared, leaving, for a brief space of time, a dark cloud, as is usual in cases of detonating meteors. The noise accompanying the fall was heard over a large extent of country, as much as 100 miles to south-west, but only a short distance north of the place of its fall. Fragments were gathered up in Iowa County, Iowa, over a district measuring four miles by seven, the large pieces all to the north and small pieces to the southern end of the area. The largest pieces weighed 74, 48, 43, and 21 pounds; many others from 8 to 15 pounds each, making a total of 500 pounds so far as found. The pieces are most of them surrounded entirely with a black coating. Some cases of fracture which evidently took place in the air were pointed out in a specimen exhibited before the association. The newly-exposed surface in such cases held what might be called a secondary coating, quite distinguishable in the specimen exhibited from the coating of the other surfaces. Another specimen exhibited showed plainly a radiated or streaked appearance, by which the direction of the flow of smelted surface matter could be ascertained. This specimen was also surrounded by a raised circlet, composed of molten particles of nickeliferous iron. In a specimen not exhibited, a like circlet having been broken across in falling, its place showed unusually large particles of iron. The path was carefully computed, and the method of the computation was given. No mere estimates were relied upon, but only such observations as could be subjected to instrumental measurement, such as in cases where the meteor was seen to pass by or close to some definite point upon some terrestrial object. The path was mapped out on the board, and remarked upon as unusually low in the hemisphere, not far from a straight line until near its close. At a distance of sixty-eight miles from the place where the largest piece fell the height was fifteen miles ; at a distance of thirty-eight miles, twelve ; at a distance of twenty-two miles, eight ; at a distance of two miles, two. These numbers refer to the nearest whole number. The angle of the path with the meridian was given as 18°, and its course could be entered on a State map by drawing a line from about four miles east of Ottumwa to a point about six miles east of Marengo. The velocity of the meteorite's motion varied very much, according to data given by different observers, from three and one-half to ten miles per second. It was thought that six or seven miles might probably be not far from a fair estimate, but the essayist did not consider any one of the numbers given as entirely trustworthy.

  Big Meteors that Fell in Iowa.
 From The Des Moines (Iowa) State Register.
  Two remarkable meteorites have fallen in Iowa within the last twenty years. Feb. 12, 1875, an exceedingly brilliant meteor, in the form of an elongated horseshoe, was seen throughout a region of at least 400 miles in length and 250 in breadth, lying in Missouri and Iowa. It is described as "without a tail, but having a flowing jacket of flame. Detonations were heard so violent as to shake the earth and to jar the windows like the shock of an earthquake," as it fell about 10:30 P. M., a few miles east of Marengo, Iowa. The ground for the space of some seven miles in length by two to four miles in breadth was strewn with fragments of this meteor varying in weight from a few ounces to seventy-four pounds.
  On May 10, 1879, a large and extraordinary luminous meteor exploded with terrific noise, followed at slight intervals with less violent detonations, and struck the earth in the edge of a ravine near Estherville, Emmet County, Iowa, penetrating to the depth of fourteen feet. Within two miles other fragments were found, one of which weighed 170 pounds and another 32 pounds. The principal mass weighed 431 pounds. All the discovered parts aggregated about 640 pounds. The one of 170 pounds is now in the cabinet of the State University of Minnesota. The composition of this aerolite is peculiar in many respects; but, as in nearly all aerolites, there is a considerable proportion of iron and nickel.
