We have extended to order four in β = 1/kBT the high-temperature series expansion for the body-centred cubic phase of solid 3He with a Hamiltonian including two-, three-, and four-particle exchange. The results are used to analyze recent experimental measurements of the specific heat at low temperature and high magnetic fields.
