The bare masses of the Brill-Lindquist black holes are introduced in a way which is applied, after straightforward modification, to the Misner-Linquist binary black-hole solution.LaTeX, 4 pagesGeneral Relativity and Quantum CosmologyOn bare masses in time-symmetric initial-value solutions for two black holestext
