of a writer, “R. W. E.” in The Ottawa Naturalist for January 
1900, who ascribes the Kiltorcan beds of Ireland to a much lower 
horizon than is generally accepted. After discussing the biologic rela- 
tions and characters of Belinurus kiltorkensis Baily, and comparing 
this species with North American as well as European examples of the 
same genus, the writer concludes thus: “I feel, then, that Belinurus 
may be safely regarded as occurring in the Upper Old Red sandstone 
of Ireland, which some authors have proposed to include in the Lower 
Carboniferous series. There seems no reason to depart from the 
determination made by Mr. Baily and Dr. Woodward thirty years 
ago, a determination that has become widely known through the works 
of Zittel and other paleontologists.” H. M. A, 
ANALYSIS OF THE MouNtT VERNON Loess. Loess occurs to a con- 
siderable depth on the hills in the vicinity of Mount Vernon, Iowa. On 
the somewhat elevated ridge on which Cornell College is located, the 
formation extends to a depth of forty feet, diminishing from the sum- 
mit. In general it overlies the Kansan and Paha drifts, and is usually 
absent over the Iowan. A brick yard is located in the Mount Vernon 
loess from which a good quality of brick is obtained. The specimen 
chosen for analysis was taken from the brick yard, eight feet below 
the surface of the earth. The analysis was made by Frank Hann in 
the chemical laboratory of Cornell College under the direction of Dr. 
N. Knight. The following results were obtained:
