  We have made simultaneous torsional oscillator and transverse NMR
measurements (at 165 kHz) on 3He contained within aerogels with nominal
densities of 1% and 2% of solid glass. The superfluid transition is seen
simultaneously by both techniques and occurs at a temperature which agrees
semi-quantitatively with that expected for homogeneous isotropic pair-breaking
scattering of 3He atoms by strands of silica. Values obtained for the
superfluid density rho_s in the 2% sample are in reasonable agreement with
those observed previously. Coupling of the torsional mode to a parasitic
resonance prevented accurate determination of rho_s for the 1% aerogel. We have
identified other resonances coupling to the torsional oscillations as sound
modes within the helium/aerogel medium.
