Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. It is a necessity of the human mind to give everything a name, thus recognising a difference between one thing and another, and recording it. Science, which is the highest development of this necessity, recognises, and records systematically, all the facts of experience, distinguishing one from another, by the most minute analysis. The Maoris even go so far as bestow on their greenstone clubs, on their tikis, and on almost every separate article, a distinct name, as if recognising an individuality, much as the old myth-makers spoke of the sword Excalibur; but the average man is usually very loose in his application of terms.
