Abstract
A recent criticism of a former paper by the author on the quasi-static contraction of interstellar clouds due to ambipolar diffusion is answered. The former paper explicitly neglected the external (intercloud) pressure, and the critical paper argued that that pressure significantly reduces the rate at which ambipolar diffusion progresses in a cloud. It also argued that neutrals should not have been assumed to remain at rest at all times. The author responds that pressure balance across the cloud surface does not at all inhibit ambipolar diffusion, and that the assumption that the neutrals remain at rest permits the effects to be isolated and individually studied.
