It is no valid objection that science as yet throws no light on the origin of Life. Who can explain what is the essence of the Attraction of gravity?" Although Leibnitz accused Newton of introducing" oceult qualities and · miracles into philosophy;" yet this unknown element of
attraction is now universally looked at as a vera causa perfectly well established.] ! . . .." ;
[I see no good reason why the views given in this volume should shock the religious feelings of any one. It is satisfactory, as showing how transient such impressions are, to remember that the greatest discovery ever made by man, namely, the law of gravity, was attacked by Leibnitz, “as subversive of natural and inferentially of revealed religion.” A celebrated author and divine, &c.,
Page 420, fifteen lines from top, after “deceitful guide," omit whole remainder of paragraph, and insert, instead, as follows:
Nevertheless, all living things have much in cominon; in their chemical composition, their cellular structure, their laws of growth, and their liability to injurious influ· ences. We see this in so trifling a circumstance as that the same poison often similarly affects plants and animals, or that the poison secreted by the gall-ily produces monstrous growths on the wild rose or oak tree. In all organic beings the union of a male and female elemental cell seems occasionally to be necessary for the production of a new being. In all, as far as is at present known, the germinal vesicle is the same. So that every individual organic being starts from a common origin. If we look even to the two main divisions—namely, to the animal and vegetable kingdoms-certain low forms are so far intermediate in character that naturalists have disputed to which kingdom they should be referred ; and on the principle of natural selection with divergence of character, it does not seem utterly incredible that from some such intermediate production both animals and plants might possibly have been developed. Therefore I should infer that probably all the organic beings which have
ever lived on this earth have descended from some one primordial form, into which life was first breathed by the Creator. But this inference is chiefly grounded on analogy, and it is immaterial whether or not it be accepted. The case is different with the members of each great class, as the Vertebrata or Articulata; for here, as has just been remarked, we have in the laws of homology and embryology, &c., some distinct evidence that all have descended from a single primordial parent.]
