A HANDBOOK OF CHEMICAL ANALYSIS (ADAPTED TO THE UNITARY NOTATION) BASED ON THE FOURTH EDITION OF DR. H. WILL'S ANLEITUNG ZUR CHEMISCHEN ANALYSE. BY F. T. CONINGTON, M.A. F.C.S. FELLOW OF CORPUS CHRISTI COLLEGE, OXFORD. LONDON LONGMAN, BROWN, GREEN, LONGMANS, AND ROBERTS. 1858 193. C. 11. PREFACE. THE main object of this work is to further the general adoption in chemical instruction of the Unitary System of notation, by furnishing the laboratory student with a manual of analysis in which this notation is adopted throughout. This system, first proposed by Gerhardt some sixteen years ago, and consistently advocated by Laurent, Williamson, Brodie, and other eminent chemists, has been gradually but surely gaining ground: until, at the present time, the only obstacle to its almost universal adoption in chemical schools is the want of books in which this system of notation is employed. This want will be supplied in the theoretical and descriptive branches of the science by the forthcoming Handbook of Chemistry by Dr. Odling: the present manual is designed to supply the same want in the analytical branch. I may add that the work was undertaken with Dr. Odling's knowledge and concurrence: and, in order to ensure uniformity between the two books on all essential points, the greater part of these sheets has been submitted to his inspection. Independently, however, of the main object with which this work has been executed, I believe that there is room in English chemical literature for a text-book which aims at comprising the best and latest methods of analysis within a moderate compass. In German chemical literature this place is filled by the last edition of Dr. H. Will's Anleitung zur |
