by Richard A. ProctorPREFACETOTHE FIFTH EDITION.IN preparing this edition, only those passages whichhave been shown by recent researches to be erroneous have been removed. It has not been thought neces-l sary, or even desirable, to modify the wording of Essays (by changes of tense or otherwise) in such a way that, as thus modified, the Essays might have appeared in 1884. In many cases this would have been altogether misleading, whereas, with the dates prefixed to the Several Essays, no misconceptions can arise.RICHARD A. PBOCTOR.--PREFACE TO SECOND EDITION.THIS edition has been carefully revised, and, in parts, considerably modified. Thus the Essay on Britain's Coal Cellars has been added, and two Essays on Government Aid to Science have been removed. I may mention that my views on the subject of the last-named Essays have changed altogether since those Essays were written— certain circumstances which have come under my observation having convinced me that more mischief than advantage would result from any wide scheme for securing Government aid for scientific researches.EICHARD A. PROCTOR.PREFACE TO FIRST EDITION.IN preparing these Essays, my chief object has been to present scientific truths in a light and readable form—clearly and simply, but with an exact adherence to the facts as I see them. I have followed — here and always—the rule of trying to explain my meaning precisely as I should wish others to explain, to myself, matters with which I was unfamiliar. Hence I have avoided that excessive simplicity which some seem to consider absolutely essential in scientific essays intended for general perusal, but which is often even more perplexing than a too technical style. The chief rule I have followed, in order to make my descriptions clear, has been to endeavour to make each sentence bear one meaning, and one only. Speaking as a reader, and especially as a reader of scientific books, I venture to express an earnest wish that this simple rule were never infringed, even to meet the requirements of style.It will hardly be necessary to mention that several of the shorter Essays are rather intended to amuse than to instruct.The Essay on the influence which marriage has been supposed to exert on the death-rate is the one referred to by Mr. Darwin at page 176 (vol. i.) of his ' Descent of Man.'EICHARD A.
