SELF-EDUCATION IN SCIENCE, ETC. 109orders were founded, <strong>and</strong> showed how <strong>of</strong>ten they gaveus a clue to the properties <strong>of</strong> large groups <strong>of</strong> species,<strong>and</strong> enabled us to detect real affinities under verydiverse external forms.I concluded by passing in review some <strong>of</strong> the bestmarked orders as illustrating these various features.Although crudely written <strong>and</strong> containing some errors,I still think it would serve as a useful lecture to anaudience generally ignorant <strong>of</strong> the whole subject, suchas the young mechanics <strong>of</strong> a manufacturing town.Its chief interest to me now is that it shows my earlybent towards classification, not the highly elaboratetype that seeks to divide <strong>and</strong> subdivide underdifferent headings with technical names, rendering thewhole scheme difficult to comprehend, <strong>and</strong> being inmost cases a hindrance rather than an aid to thelearner, but a simple <strong>and</strong> intelligible classificationwhich recognizes <strong>and</strong> defines all great natural groups,<strong>and</strong> does not needlessly multiply them on account <strong>of</strong>minute technical differences.
