Soits of Illinois. By Prank Leverett. (Final Rept. 111. Board of 
World's Fair Com., pp. 77-92, 1 map, 1895.) In this paper the author 
reports his observations on the soils, especially those dependent on 
glacial action, in the state of Illinois. He classifies them as (1) resi- 
duary, from the decay of the underlying rocks and therefore extra 
morainic, (2) glacial clays, (3) gravelly washes. (4) glacial drainage 
sands, (5) loess or pervious silts, (6 and 7) silts slightly pervious to 
water, (8) peat and marl. A short glacial history of the state follows 
showing how, in the author's opinion, each of these soils was formed.

1. Ein prakambrisehes Foxsil. The minute egg-shaped bodies in 
question have been known to Swedish geologists for some years, from 
the Visingso group of pre-Cambrian slates on lake Vettern. The author 
has analyzed them closely and finds them to be spherical chitinous sacks 
with a very thin and simple wall. No clew to the real nature of the 
bodies reveals itself, but the possibility of their being eggs of trilobites 
is suggested. 
2. Conularia loculata. An interesting new structural feature for 
this genus is here brought out. The segmental lines which symmelri 
cally and vertically divide each face of the shell are shown to represent 
internal erect lamella? which bifurcate on their inner edges and, though 
not coming into contact with one another, divide the inner shell cavity 
into elongated compartments. This structure emphasizes the ahead) 
recognized differences between Conularia and the pteropods.
