Specific-heat data around the critical temperature Tc = 90 K of polycrystalline YBal 8Cao 2Cu408 show a discontinui\_ty ACp/Tc = 22 mJ/mol K z. In undoped YBa2Cu408 and in YBa2Cu307,'the corresponding anomalies are 15 mJ/mol K z and 55 mJ/mol K z. The in-plane London penetration depthoof the Ca-dope
The specific heat of high-purity, sintered, YBa2Cu307-x powder has been measured. The lowtemperature specific heat had only a linear term (with a zero-field coefficient of 4.37 mJ mole K 2) and a cubic term (corresponding to a Debye temperature of 375 K); both terms varied with field. No Schottky pe
