Maxwell's equation (G), viewed in isolation as printed in the 1864 paper, at first seems to say that ‍ ρ + ∇⋅ D = 0. However, if we trace the signs through the previous two triplets of equations, we see that what seem to be the components of D are in fact the components of − D. The notation used in Maxwell's later Treatise on Electricity and Magnetism is different, and avoids the misleading first impression.
