until since the ett, made by Prof. Swallow, of Missouri, of the 
existence of Permian rocks in the Territory of Kansas which was soon 
den. Having thus had my attention neta to this subject, 
after a review of some of the fossils found in Bureau, La Salle, and Henry

Salle rocks are of the same age as those containing many of the organic 
remains described sa = gentlemen above named as belonging to the

doubtedly, to the Permian period, the great pra gh ers rage % mee

mention the occurrence in the slates of scales of a Platysomus, a genus: 
that belongs to the Permian epoch.
