We have observed
the nearby isolated globule Barnard 68 (B68) in the 
and 
inversion lines of ammonia. The gas kinetic temperature derived
from these is
. The observed line-widths are almost
thermal: 
(
),
supporting the earlier hypothesis that B68 is in hydrostatic
equilibrium.
The kinetic temperature is an input
parameter to the physical cloud model put forward recently, and we
discuss the impact of the new value in this context.
