It will be found fully as interesting as any of its predeces sors on the whole, perhaps, more so, for science advances with more rapid strides every day, and we find ourselves drawing nearer and nearer a future which, so far as human knowledge is concerned, will be a true golden age.<br><br>In a work of this kind absolute accuracy is of course unattainable.<br><br>About the Publisher<br><br>Forgotten Books publishes hundreds of thousands of rare and classic books.
