The concept of an H-cordial graph is introduced by 1. Cahit in 1996 (Bulletin of the ICA). But that paper has some lacunae and invalid statements. We try to prove the statements whose proofs in Cahit's paper are incomplete, and also we provide some counterexamples. We also prove necessary and sufficient conditions for H-cordiality of complete graphs and wheels and H2-cordiality of wheels.
