Several expression which are apparently different from each other have been derived for the first correction to Bogoliubov's expression for the ground-state energy of a Bose system. The relationship between these expressions is investigated. It is found that the expressions of Hiroike, Brueckner-Lee and Lee are equivalent to each other. It is also found that the expressions of Bogoliubov-Zubarev and Takahashi, which are equivalent to each other, do not always agree with the above-mentioned expressions. A sufficient condition for the interaction potential is derived in order that such a disagreement does not arise.
