We present a Keck/MOSFIRE, rest-optical, composite spectrum of 16 typical, gravitationally-lensed, star-forming, dwarf galaxies at 1 . 7 (cid:46) z (cid:46) 2 . 6 ( z mean = 2 . 30), all chosen independent of emission-line strength. These galaxies have a median stellar mass of log( M ∗ /M (cid:12) ) med = 8.29 and a median star formation rate of SFR medH α = 2 . 25 M (cid:12) yr − 1 . We measure the faint, electron-temperature-sensitive, [O III ] λ 4363 emission line at 2 . 5 σ (4 . 1 σ ) signi…
