Mineralogy pertaining to my chair of physical science in the Iowa State University, I felt it my duty to furnish the mineralogical cabinets with good specimens of the meteorites which fell in my neighborhood. I have, through the personal and financial assistance of the Hon. John P. Irish, of Iowa City, brought together three collections, the first two of which have been photographed. The subjoined cut is a copy of the photograph of the first collection. It shows the general form of each of the specimens, numbered in the order of their weight. The photographs themselves, in one-fifth natural size, are very excellent, permitting even a close study of the granulations and surface. The above cut gives the specimens in one-seventh of their natural size.
The following catalogue gives the specimens of my collections in the order of their weight. The numbers correspond with those on the map of Iowa Township. No. on the map indicates the "Sherlock Stone," the first one found:

But a few days ago (on June 30th) I received a dispatch from the meteorite headquarters that quite a large specimen had been found. Since, an additional, somewhat smaller stone has been found on the same section of land, namely, on section thirty of the township, directly north of Iowa Township—or about two miles north of the spot A in section six of the map, but a little south of the society village called Amana vor der Höhe. I have visited this place, and been kindly permitted to examine these truly beautiful specimens. The larger meteorite forms an irregular, rounded rhomb, 15 inches diagonal and 8
