While the various departments of the science of Man are extremely multifarious, ranging from body to mind, from language to music, from fire — making to morals, they are all matters to whose nature and history every well informed person ought to give some thought. It is much, however, for any single writer to venture to deal even in the most elementary way with so immense a variety of subjects. In such a task I have the right to ask that errors and imperfections should be lightly judged. I could not have attempted it at all but for the help of friends eminent in various branches of the science, whom I have been able to consult on doubtful and difficult points. My acknowledgments are especially due to Pro fessor Huxley and Dr. E. A. Freeman, Sir Henry Maine, Dr. Birch, Mr. Franks, Professor Flower, major-general pitt-rivers, Professor Sayce, Dr. Beddoe, Dr. D. H. Tuke, Professor W. K. Douglas, Mr. Russell Martineau, Mr. R. Garnett, Mr. Henry Sweet, Mr. Rudler, and many other friends whom I can only thank unnamed.
