The frequent use of the first person singular in the text of this article makes it necessary that we should explain how the work has been divided between us. Mr. Fell, who was resident for two years at the British School at Rome, first as Craven Student of the University of Cambridge, and then as Gilchrist Student of the Faculty of Archaeology, History and Letters, is responsible for Section A (The Via Flaminia in History), and Dr. Ashby for Section B (The Topography of the Via Flaminia from Rome to Narni). In Section C the description of the road from Narni to Forum Flaminii by Terni and Spoleto is the work of Dr. Ashby, while from Narni to Forum Flaminii by Bevagna it is the joint work of both writers: but the concluding portion of the road was studied and described by Mr. Fell alone. The whole article has, however, been carefully read by both of us.
