Query: A Comment on "Brans-Dicke Cosmology with a scalar field potential"   We show that a recent letter claiming to present exact cosmological solutions
in Brans-Dicke theory actually uses a flawed set of equations as the starting
point for their analysis. The results presented in the letter are therefore not
valid.
