 science concerned with the flight of an aerodrome. Thus the present work may be entitled a Treatise on Aerodromics, and the whole subject of aerial flight would be dealt with at a College or University by a lecturer or professor of Aerodromics.

{{hi|{{sc|Periptery}} (Diet.), proposed by the author in its present usage as denoting the region round about the wing or in the vicinity of the aerofoil (Greek. {{Greek|περι}} and {{greek|πτερόν}}), § 107. Hence peripteral, as in peripteral theory (Ch. 4), peripteral area, § 210; peripteral zone, § 210; peripteral motion, § 126 {see also footnote 2, p, viii.. Preface). Hence also peripteroid motion, §nb122 (Greek, {{Greek|περι}}, {{greek|πτερόν}} and {{Greek|ειδος}}, the form of flow proper to the inviscid fluid in a doubly connected region, resulting from the superposition of a cyclic motion on one of translation. Resembling the motion in the pieriptery, lit. round-about-the-wing-like.}}
