Book Description
Excerpt from The Ferns (Filicales) Treated Comparatively With a View to Their Natural Classification, Vol. 2: The Eusporangiatae and Other Relatively Primitive Ferns As a result of simple induction from the observed facts it may be stated generally that simple hairs are a primitive feature, and that branched hairs and in particular flattened scales are an indication of advance from that simple state. Evidence of this advance parallel with other indications of advance in other characters may be found in various phyletic sequences, and this fully substantiates the general correctness of the conclusion thus stated (chapter XI).

Book Description
Excerpt from The Ferns (Filicales) Treated Comparatively With a View to Their Natural Classification, Vol. 1: Analytical Examination of the Criteria of Comparison Little do ye know your own blessedness; for to travel hopefully is a better thing than to arrive, and the true success is to labour. R. L. Stevenson, Essay on El Dorado. IN this passage Stevenson enunciates a truth that applies with singular force to those who enter on morphological enquiry. To travel hopefully is the chosen pursuit of all who study large groups of organisms with a view to reducing them to order, so as to throw light on their origin and evolution. In such quests no one need expect under present conditions to arrive at the final destination of complete and assured knowledge. If any one should indulge this hope his disappointment is certain. Even if he did so arrive, and found himself able fully to demonstrate the whole truth, how greatly would the quest lose in its interest. It is in the pursuit of his El Dorado of evolutionary history, not in the arrival there, that the true blessedness of the morphologist lies. It behoves then those who travel on this journey not to hurry unduly, but to consider with critical care the manner of their journeying, rather than to seek short cuts to an elusive goal.
