  The fluid dynamic limit of the Boltzmann equation leading to the Euler
equations for an incompressible fluid with constant density in the presence of
material boundaries shares some important features with the better known
inviscid limit of the Navier-Stokes equations. The present paper slightly
extends recent results from [C. Bardos, F. Golse, L. Paillard, Comm. Math.
Sci., 10 (2012), 159--190] to the case of boundary conditions for the Boltzmann
equation more general than Maxwell's accomodation condition.
