G. Dragendorff "Plant Analysis: Qualitative and Quantitative (Classic Reprint)" - used book

Excerpt from Plant Analysis: Qualitative and Quantitative Soon after the publication in German of Professor Dragendorff's 'Pflanzenanalyse, ' it was suggested to me that an English translation of the work would supply a want keenly felt by both English chemists and English pharmacists. A thorough knowledge of the German language and a practical acquaintance with many of the processes described, gained whilst a pupil in the author's laboratory, would, it was thought, enable me to offer a translation of trustworthy accuracy; and this has been my endeavour. Such alterations or additions as have been considered needful have been made in the text, the proof-sheets of which have been submitted to the author. Most of the references have been checked, as accuracy in this particular was deemed very important. To many of them, however, access could not easily be had; but it is hoped that even in these cases very few will be found to be incorrect. To secure to English readers the usefulness of the numerous quotations, reference has been frequently made, in brackets, to abstracts or translations that have appeared in English journals. One word has been employed in a somewhat unusual sense. The solution obtained by treating a substance with spirit is called a 'tincture, ' with cold water an 'infusion, ' and so on. All such solutions have been included in the general term 'extract;' the latter will not, therefore, necessarily mean the dry residue commonly called 'extract.'
