Brit.

/ˈsəːfᵻs ˌmaʊnt/, U.S.

/ˈsərfəs ˌmaʊnt/

Origin: Formed within English, by compounding. Etymons: surface n., mount n.²

Etymology: < surface n. + mount n.² With sense 2 compare earlier surface-mounted adj.

1. Biology. A specimen mounted to permit (microscopic) examination or photographing of its surface, as distinct from a section (cf. mount n.² 5d). Now disused.
