It is surprising, considering the gigantic strides effected by modern science, how many of the errors and prejudices engendered by the ignorance of the dark ages remain current in the world in its present days of enlightenment. Like the winged seeds of certain weeds, their light and impalpable nature renders them only the more difficult of extirpation. A cursory review and refutation of these popular prejudices and vulgar errors has been attempted in the following Manual. A more scientific analysis of so spreading a field would have expanded into a CyclopÆdia. But the ancient traditions and modern instances collected in its pages may afford the reader amusement and instruction for the passing hour, as well as an incentive to more profound investigations in hours to come.
