The various analyses reported above show that the area of ground where the phenomenon is reported to have been observed by Mr. Nicolai has indeed undergone certain alterations of a mechanical and thermal nature, as follows:

In summary, we find that a strong mechanical pressure, probably due to a shock, was exerted at the surface of the "round." Superficial modification of the structure (striations and erosion) took place. A heating effect which may have been caused by this shock, but which did not exceed 600 degrees, was subsequently observed. Foreign elements consisting in a small quantity of iron (or iron oxyde) over a limestone grain, and a small but detectable amount of phosphate and zinc were deposited at the site.
