DR. THOMAS YOUNG ON SPIRITS. DR. THOMAS YOUNG, the colleague of Sir Humphrey Davy, and one of the predecessors of Faraday and Tyndall, as Professor of Natural Philosophy at the Royal Institution, has placed on record some specula tions of his own respecting Spiritual beings, considered from a physical science point of view. Dr. Young was the first in this country to work out and advocate the wave theory of light, but he was crushed for the time being by the great weight of authority brought to bear against him by Sir Isaac Newton and Lord Brougham, who held that light was not wave motion, but consisted of particles shot out with infinite velocity from the luminous source. It is now known that Dr. Thomas Young was in the right, and Professor Tyndall, F.R.S., has scarcely delivered a single lecture on light within the last two years, in which he has not called attention to the eminence of Young as a philosopher, and pointed out how his labours were long overlooked because of the eminence of those who held opposing opinions. Strange to say, Young held more accurate views in his day as to the nature of spiritual beings than Fara day and Tyndall ever attained, notwithstanding the rich rain of evidence falling on every side of the latter philosophers—evidence whieh they refused to examine. Here is a long-forgotten paragraph written by Dr. Thomas Young, and the words thereof will live in history:  "We see forms of matter differing in subtilty and mobility under the names of solids, liquids, and gases; above these are the semi-material existences which produce the phenomena of electricity and magnetism, and either caloric or universal ether higher still perhaps are the causes of gravita tion, and the immediate agents in attractions of all kinds, whieh exhibit some phenomena apparently still more remote from all that is compatible with material bodies ; and of these different orders of beings the more refined and immaterial seem to freely pervade the grosser. It seems, therefore, natural to believe that the analogy may be continued still further, until it rises into existence absolutely immaterial and spiritual. We know not but that thousands of spiritual worlds may exist unseen for ever by human eyes; nor have we any reason to suppose that even the presence of matter in a given spot necessarily excludes those exist ences from it. Those who maintain that nature always teems with life wherever living beings can be placed, may therefore speculate with freedom on the possibility of independent worlds; some existing in different parts of space, others pervading each other, unseen and un known, in the same space, and others again to which space may not be a necessary mode of existence. THE SPIRITUAL LIBRAY—The only lending library in London for books on Spiritualism and kindred subjects is that belonging to Mr. James Burns, bookseller and stationer, 15, Southampton-row, Holborn, W.C. Mr. Burns has fitted up rooms on the premises wherein friendly meetings for the furtherance of the Spiritual cause often take place. In the course of September last a meeting was held in these rooms under the presidency of Mr. Coleman, to welcome an eminent American medium, Mr. J. M. Peebles, consul at Trebizonde to the Government of the United States, and one of the editors of The Banner of Light, the chief newspaper of the American Spiritualists. At that meeting Mr. Burns narrated how he first began the formation of the Spiritual Library by the importation of a small box of books from New York, and how the undertaking grew gradually until his little establish ment in Wellington-road, Camberwell, became very well known to those who required scarce books on progressive sub jects connected with man. The growth of modern Spiritualism at last rendered it advisable for him to take his present more extensive and central premises. Spiritualism is known to have no more unselfish and hard-working advocate anywhere than Mr. Burns, in evidence of which it may be stated that although he is the owner of one Spiritual periodical, Human Nature, he placed every facility in the way of the issue of this new journal, The Spiritualist, because he thought it would helt the movement. There are so many points wherein the two periodicals entirely differ from each other that it is hoped that injurious competition has been avoided. The work that Mr. Burns has performed for many years past, makes it a duty on the part of Spiritualists to strengthen his hands in ever possible way in his new establishment. APPARITIONS.— You can scarcely select hap-hazard a dozen families, without finding one or two members of them who have received at the moment of the death of some near relative, a communication announcing the fact at a distance. These communications are often made by the dying person appearing to some member of the family at the moment of passing away. The death moment seems the most easy one in which tomake such communications. Notwithstanding the enormous number of such cases, some of them supported with such striking collateral proof as to remove all doubt, the pos sessors of such information are afraid to narrate these interest ing facts except under the seal of confidence, because the world at large ridicules that which it does not understand.— Varley.
