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
In order to investigate the nature of the superconducting transition of YBa2Cu307, polycrystalline samples with calorimetric transition widths of 0.4 to 0.5 K were selected. Their specific heat was measured with 0.01% resolution and 0.5% accuracy. The models used to analyze the data from To/2 to 2T
