Having been intimately associated with Archibald Cockren during the past ten years, and having long since I learn to place implicit confidence in his efficiency and reliability in all matters to which he has devoted his many remarkable gifts and talents, it affords me real pleasure to write a few words by way of introduction to 'Alchemy Rediscovered and Restored.' In this book he tells of the sensational work which he has accomplished in once more bringing to light, and to the service of humanity, secrets which baffled the majority of scientists of all ages, and which, for several centuries, have been buried in a grave of doubt and skeptical tradition. That this grave should at last have been opened, and that the real, albeit hidden secrets which it contained should now stand revealed and proclaimed, must undoubtedly be regarded as an epoch-making event. I do not myself claim to have any scientific knowledge whatever, but seeing is believing, and I have been privileged to keep in close touch with the author's experiments from the very beginning. Not only have I seen the results achieved, but I, among many others, have been able to test and pay grateful tribute to the efficacy of the Elixirs produced by the alchemical process. These, one may venture to assert, cannot fail as they become better known to prove a very valuable addition to the remedies at present available to mankind. There is no question of the claims which are put forward in this book being taken on trust. On the contrary they are open to the fullest examination. The proofs are there and they can safely be left to speak for themselves, in the light of the outcome of any investigations to which they may be subjected. Seeing the far-reaching importance of the author's researches and discoveries it is necessary that some account should be given of his career, and of those qualifications in the wide field of physiology which entitle him to consideration in questions of the treatment of human ailments. After the necessary period of training he was, in 1904, certificated at the National Hospital for Paralysis and Epilepsy as fully qualified for all purposes of massage, remedial exercises, and electrical treatment. From this hospital he passed on to the staff of the Great Northern Central Hospital, where he remained for several years. From 1908 onwards, however, he was able to devote part of his time to the private practice in which he then for the first time established himself in the West End of London. This practice had necessarily to be given up during the War. For over twenty years he has been a keen student of the sciences of metallurgy, No-chemistry, and bacteriology, and it will thus be seen that in the claims he now advances in this book he writes with that measure of authority which a life devoted to the alleviation of suffering, and to the effective treatment of human ailments, undoubtedly confers on him. It is given to few men to make such momentous discoveries as have rewarded his persistent work and patience. His work has, indeed, to my knowledge, often been pursued under conditions of great difficulty and disappointment. May what he has accomplished in the interests of science and of the human race bring him the reward which he deserves--the reward of general recognition and appreciation of the results achieved.
