Excerpt from Palaeontographica Americana, 1916-1929, Vol. 1 The first of these papers, unpretentious and seemingly easy of preparation, has cost the author a vast amount of study here and elsewhere to make sure that no serious omissions of specific or varietal forms have been made either in the text or plates, and that the figures and text indicate clearly the characteristic features of each form discussed.

Excerpt from Palaeontographica Americana, Vol. 3: 1941-1953 So different have our morphological deductions been from the currentlv ac cepted interpretations of the structures, and the phyletic implications have been of such exceptional interest in view of their bearing upon the theories of relation ship recently proposed l)y Teichert and Kobayashi, that it is felt progress will be best served by the publication of our observations at the present time. These results are far from complete. Adequate material for the study of many of the crucial genera by means of thin sections has been lacking. Doubtless the present findings give only a faint indication of the rich mine of morphological informa tion which awaits a more comprehensive study along similar lines. Particularly important is the investigation of the endoceroids by this method, for it has been found that in many cases opaque sections fail to give any indication of the true structures.

Excerpt from Palaeontographica Americana, Vol. 6: 1968-1970 The Upper Freeport, uppermost Allegheny, is more or less continuous throughout the Appalachian Coal Basin. One of the few areas of this coal, bearing an identifiable compression flora, occurs near Kimberly, northern Athens County, in southeastern Ohio. The coal was strip mined over a period of approximately 10 years and resulted in about 20 miles of essentially continuous exposures of the coal. In this area, the diversified compression flora occurs in a discontinuous shale parting in the coal. The shale part ing ranges from a few inches up to three feet in thickness.
