Taking advantage of the special attention paid at present to certain astronomical disquisitions, the author called attention to a particular point connected with the moon, which was first stated by the author of “The Plurality of Worlds,” and then made by him to prove that the moon must be uninhabited, and thence to lead to the conclusion that all the other planets were uninhabited also. This point was, that “observations having been made on the moon abundantly sufficient to detect the change caused by the growth of such cities as Manchester and Birmingham, no such changes having been perceived, the theory of non-habitation may be indulged in.”
