the action of gravity, in a way to excite the astonishment of whole circles. And this miraculous prerogative, we are told, is, itself, but an exemplification of natural law. But, assuming the truth of the spiritualist's view, we have simply come to an end of natural law. If the wonders alleged be true, where is the basis of trust in the regular course of Nature? If the uniformities of phenomena that science assumes to have discovered can, as a matter of fact, be disturbed by the capricious incursions of unseen beings, then there are no such uniformities; and the conception of law, instead of being the most fundamental conviction of the scientific mind, is an illusion to be abandoned. Anxiety about the constancy of these laws is, however, the last thing that troubles scientific men, and their repose of mind upon this subject sufficiently accounts for their general indifference to the claims of spiritualism.
Our readers will well remember the row occasioned last year when Prof. Huxley said that the evidence of the truth of evolution must be accepted as demonstrative. "We mark with interest the decisive indications that are accumulating in confirmation of Prof. Huxley's position. Another President of the British Association for the Advancement of Science has spoken upon the subject, under the responsibilities of his distinguished position, and in entire corroboration of the avowals of former presidents of that body for the last dozen years in relation to this question. His indorsement of evolutionary doctrine is emphatic and unqualified. Prof. Allen Thomson has been well known as an eminent cultivator of biology; but he comes forward now as a new authority, and will be listened to without the prejudice which attaches to the names of those men who have been in the thick of the fight for the last twenty years. The topic of the presidential address is the "Development of the Forms of Animal Life," and we here quote the opening passages, describing the remarkable change in the manner of viewing biological questions which has taken place during the last half century. President Thomson says:
"On the Continent of Europe, it is true, some bold speculators, such as Goethe, Oken, Lamarck, and Geoffroy St. Hilaire, had in the end of the last and commence-
