Synopsis
Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Présentation de l'éditeur
The following loose-leaf Laboratory Directions which have been tried and corrected in our laboratories for the past five years are now presented in printed form for the benefit of other institutions. In the University of Pittsburgh the student will, on an average, complete one set of experiments per three-hour period. He is scheduled for two such periods per week throughout the college year. Results are noted on a separate sheet and submitted with the instruction sheet at the end of each period. Both the direction sheet and record sheet are stamped by the instructor before they are returned to the student. A word should be said about the study questions which constitute the second half of this volume. These serve as a study guide for the student. Questions of major importance are starred. All recitations and examinations are conducted on the basis of these questions so that a uniform system is employed even where a dozen or more instructors handle different sections. The method has met with such marked success here that there is no doubt about its success when introduced into other institutions. The authors will welcome notice of errors found in this volume and invite suggestions from those who have occasion to use it. ALEXANDER SILVERMAN. ADELBERT W. HARVEY. School of Chemistry, University of Pittsburgh, Sept. 1, 1919.
