o pieces and the fragments reunited at least twice before it en- 
tered the earth's atmosphere. It is in fact a conglomerate in 
which the component pebbles are themselves conglomeritic. 
In searching for a cause of this singular structure Dr. Reusch 
cites the probable conclusion, deduced from the periodicity of 
meteoric showers that these bodies travel through the interstel- 
lar spaces in flocks, like the component particles of a comet, and 
with similarly elongated orbits. In perihelion they are rent in 
fragments and partly melted by the intense heat. The frag- 
ments may be rounded by mutual impact and attrition, then re- 
cemented by the molten matter. The Staelldall meteorite 
shows rounded fragments in a magma of brownish glass.

Later Cretaceous in Iowa. Mr. A. G. Wilson, of 
Hopkinton, Iowa, states in correspondence that at about five 
miles north of Mt. Vernon, in Linn county, Iowa, a fossil, sup- 
posed to be Belem7iitella muci'onata was found about forty feet 
below the surface, in the drift, and its origin could not have 
been much further west. In vol. i of the final report of the 
Minnesota geological survey, page 599, Mr. Warren Upham 
states that the shales of the Fort Pierre and Fox Hills groups are 
indicated by fossils found 'ui situ in numerous instances in Yel- 
low Medicine and Lyon coimties; also on p. 5S4-85 that Bacu- 
lites and Inoceramus are frequently found in the drift in Brown 
county. Mr. J. H. Kloos states {^Am. Jour. Sci. (3), iii, 24), 
that Baciilites has been found in Nobles county, and infers that 
the latest members of the Cretaceous exist in Minnesota. 
Prof. E. Haworth also writes that the fossil plant mentioned 
by Dr. C. A. White, in his article on p. 237, indicating the 
Dakota group of the Cretaceous, was found at Oskaloosa, Iowa, 
about eighty miles nearly due south from the locality of the in- 
vertebrate fossils, and in a boulder lying on the surf ace. 
Probably the most eastern point in the Northwest at which 
the Cretaceous has been identified, is in the northern part of 
Goodhue county Minnesota, where shales and sandstones of the 
Dakota group are opened up for pottery-ware. Dr. Lesque- 
reux has fully identified the plant remains and refers them to 
the earlier Cretaceous. This locality will be described in the 
forth-coming vol. ii, of the final report of the Minnesota survey.
