If one copied this Chicago River Plan I should ask for two building like this one. One to be devoted to Mineralogy, Geology and Paleontology. The other for Zoology, Botany and Ethnography. The plan provided is to join both houses one another. Thus: [Latin] stairs Biology Geology Paleontlogy. Orthos masonmerian appears to occur in a diomite at Kannahan, Ills. Brachs from Chicags nigjaran vary far in number and unlike those of the South or East. Specific nigjarenzi cutaway not the N.Y. form, they much thinner and less drawn out. D. gilberti is of the radiale type. I. Eudora here does not both the baldum forms at once. I. radiata here cutaway as typical pleurum slice. Orthomella semifusciata occurs at Bridgport. Maybe this form but appears the much thicker. Immunovilla frison here in fine form. Anastrophia internescens look to me to be different.
