Three large nautiloid cephalopods have been collected from the Cambridge Limestone of the Conemaugh series at New Concord, Ohio. Unique size, morphology, and the appearance of transverse crenulations on the body chamber are significant in determining these specimens to represent a new species of the genus Solenochilus. Discovery of this new species in Ohio confirms the wide geographic distribution of large representatives of Solenochilus and may be significant in the study of paleoecological conditions.

Buried Kansan drift and Yarmouth soil beneath Illinoian drift are described from three locations south of the Wisconsin drift border in southeastern Indiana. The occurrence in Kansan drift of bright red, clayey, non-calcareous, limestone-derived soil inclusions, and abundant residual chert cobbles from the local Silurian Laurel Limestone suggest that the Kansan ice may have been the first to reach this area. The scattered upland erratics in northern Kentucky, therefore, seem more certainly to be Kansan in age, as suggested originally by Leverett. The Townsend Farm section provides a basis for geologic-climate subdivisions of the Kansan Stage in southeastern Indiana, named as follows: Kansan Stage Columbia Stade Garrison Creek Interstade Alpine Stade The slightly greater depth of leaching of the Yarmouth soil in the Townsend Farm section as compared to depths in similar buried Sangamon soils in southeastern Indiana suggests that the Yarmouth interglacial interval was slightly longer than the Sangamon interglacial interval in this area.

M. This paper reports, for solutions of 0.001 M uranyl sulfate and 0.005 M oxalic acid, a 10-degree temperature coefficient, up to 85°C (using a base temperature of 25°) of 1.02±0.01 at 254 m/x. Measurements in more dilute solutions show a decrease to approximately unity at 0.00025 M uranyl sulfate—0.00125 M oxalic acid, with indication that it may become less than unity on further dilution. Quantum yields measured (using uranyl oxalate as standard), by students under a National Science Foundation "pilot" undergraduate participation project, on actinometers at 254 rn.fi, were for (1) malachite green leucocyanide, 0.9; (2) monochloroacetic acid, 0.3; and (3) potassium ferrioxalate, 1.24 moles per einstein.

The taxonomic status of the genus Diogmites has been the subject of controversy for many years, but it is now recognized as a valid genus, separable from Deromyia (with which it has been synonymized by many workers) by a number of characters. Diogmites is represented in eastern United States by 12 species: basalts (Walker), neoternatus (Bromley), ternatus Loew, discolor Loew, missouriensis Bromley, properans Bromley, platypterus Loew, misellus Loew, salutans Bromley, crudelis Bromley, esuriens Bromley, and rubrodorsatus, a new species described in this paper. This paper contains descriptions of these 12 species, and notes on their occurrence in eastern United States.

I, Radiocarbon Dates and Pollen Stratigraphy of Silver Lake, Logan County, Ohio Ogden, J. Gordon, III Radiocarbon and pollen analysis of a sediment core (8.9 m) from Silver Lake in central Ohio indicates that deposition began in late Woodfordian time (11,000-14,000 radiocarbon years ago) and has been continuous to the present. The pollen sequence includes a basal spruce-fir pollen zone, changing abruptly to oak-elm immediately above a radiocarbon date of 9800 ± 210 (OWU-39). A total of 19 radiocarbon dates document the climatic and environmental changes inferred from the sediment record. The Xerothermic interval of Sears (1942c) within the Hypsithermal (Deevey and Flint, 1957) is bracketed by radiocarbon dates (1300-3600 years, B.P.) and a distinct minimum in beech pollen. The presence of Zea pollen stratigraphically lower than the sharp rise in Ambrosia pollen which marks the advent of European settlers is believed to indicate pre-colonization Indian agriculture.

Thyroid glands from 167 pheasants (Korean-Phasianus colchicus karpowi, Persian- Phasianus colchicus persicus, green-Phasianus versicolor, and Reeves-Syrmaticus reevesii) were examined to determine if there were a seasonal or sexual variation in (1) the weight of the thyroid gland and (2) thyroid activity as determined by histological techniques. A Thyroid Activity Index, which histologically rates thyroid activity from 1 to 5 (inactive to very active), was employed to evaluate the functional state of the gland. Five males and five females each of the pheasant groups were sacrificed in January, April, July, and October. Generally, the thyroid glands were most active in January and April and least active in July and October. An inverse relationship seemed to exist: the lighter the gland, the more active it is, and the heavier the gland, the less active it is.

Charles; Wallin, Harold E. The thyroid glands of the house sparrow and other small birds in the Cleveland region have greater secretory activity during late autumn and winter than during late spring and summer. Evidence for this is the presence, during the winter, of high epithelial cells surrounding the follicles, of smaller follicles, and of lesser volumes and weights of the whole thyroid. Large-sized species have larger thyroids, both absolute and relative to body weight, than do small species. With certain precautions, changes in the size of the thyroids serve as a useful index of inverse variations in secretory activity intra-specifically, but not inter-specifically.

North-south-trending and arcuate lobate moraine systems occur in LaSalle County. The till of the arcuate system is characterized and distinguishable by relatively coarse texture, high magnetic susceptibility, carbonate, and zirconium contents, as compared with the north-south moraine system. The arcuate system seems to be particularly influenced by Ordovician and Silurian rocks. Illite is the dominant clay mineral of all tills. Iron-rich chlorite is markedly oxidized in the more permeable tills of the arcuate system.
