We consider several kinds of ideals described by some densities. We present connections between Erdos-Ulam, density, matrix summability and generalized density ideals and show that a certain inaccuracy in Farah's definition of density ideals leads to Farah's characterization when density ideals are Erdos-Ulam ideals being incorrect.
