It is anticipated that this work will be one of the most important publications of the autumn season. Besides giving full and extremely interesting details of the great scientist's early life and education, his first inclination and attraction towards science, and an anecdotal narrative of his travels on the Amazon and in the Malay Archipelago, it relates the historic incidents connected with his association with Darwin, gives full accounts of all the people he met, and a very particular history of his investigation of Spiritualism and the various controversies involved by his theories. The book is written in a fascinatingly open and candid style, and is sure to be widely read. _THE LATEST TRIUMPH OF SCIENCE_ =THE ORIGIN OF LIFE: Its Physical Basis and Definition.= By J. BUTLER BURKE. With Photographs, Diagrams, etc. Demy 8vo, 16_s._ net. While experimenting at the Cavendish Laboratory, Cambridge, to determine the effect of radium on sterilised bouillon, Mr. Burke recently found that he could secure the apparently spontaneous generation of growths, resembling bacteria, but which were neither bacteria nor crystals. They were termed "Radiobes." These bodies have since been examined by many eminent men of science, to whom they appear to be in a critical state between the vegetable and mineral kingdoms. This discovery has since been the subject of extensive comment in the publications of practically every civilised country. It is believed to be of such importance that by many it is acclaimed to be one of the great scientific achievements of the age, and no doubt will rank as one of the few supremely important discoveries for all time. Mr. Burke has put the results of his investigations and discovery into a book, and there is little doubt that it will be eagerly looked forward to by the whole of the scientific world, and its importance cannot be easily estimated. _A NEW WORK BY W. H. MALLOCK_ =THE RECONSTRUCTION OF BELIEF.= By W. H. MALLOCK, Author of 'Religion as a Credible Doctrine.' Demy 8vo, 12_s._ net.
