Abstract
Professor Linsay has called my attention to the need for an examination of these compounds, with a view to ascertaining whether they are ever used in the Singular by Latin writers, or always in the Plural. From a scholium, probably by Donatus, on Aen. X. 173: insula inexhaustis Chalybum generosa metallis, has come a gloss which appears in the Ansileubus Glossary in two forms: FR 205 Frofra : insula Tirreno mari in quo ferrifodina exercentur, RU 77 Rufa: insula Tirreni maris in qua ferrifodina exercetur
