Abstract
Details are given of the construction of a calorimeter to operate in the range 1 2 to 4.2 $^\circ$K. Analyses of the results obtained for several pure metals (Cu, Ag, Pt, Al, Ni, Fe, Co) are given for various weighting schemes in reducing the results. The effects of errors due to the possible presence of a Kapitza boundary layer affecting the temperatures deduced from vapour pressure bulb measurements are considered. The results are analysed with a view to detecting further lattice contributions to the specific heat (T$^5$ terms) and (in the case of ferromagnetics) spin wave contributions. The nuclear contribution and the effective field is evaluated for cobalt.
