We have studied by optical microscopy, small-angle light
scattering, and rheology, the behavior under shear flow of a
phase-separated lamellar-sponge 
ternary mixture. We
observe in the 
-rich region 
the existence of a Newtonian assembly made of closed
compact monodisperse lamellar droplets immersed
in the sponge phase. Contrary to the classical
onion glassy texture obtained upon shearing phases, the
droplet size scales herein as 
, the
inverse of the shear rate.
This result is in good agreement with Taylor's picture. Above a
critical shear rate, 
, the droplets
organize to form a single colloidal crystal whose
lattice size varies as 
.
