Excerpt from book: same defects are found as in the work of Haushofer, with immaterial corrections. The expectation, awakened by the second part of the title, is but scantily satisfied. In a comprehensive sketch, several short papers ought to have been mentioned, and those of O. Lehmann and of Michel-Levy and Bourgeois should have been reviewed more fully, but this would have filled thrice the space available for these introductory remarks. I have aimed at giving a summary of the development of micro- chemical analysis during the last ten years, and at the same time an outline of the task undertaken by the inventors of this new branch of chemistry. II. AIM OF MICROCHEMICAL ANALYSIS The memoirs of Haushofer and of Klement and Renard have been of great value to workers with the microscope, whereas they have not found entrance in chemical laboratories. From this circumstance the conclusion might be drawn, that the idea of Haushofer has no vitality, and that microchemical tests ought to remain, where they originated, in the study of the micro- scopist. An improvement of Haushofer's idea may be found in extending its range. I venture to say that, by assiduous study, microchemical analysis will be developed into a system that will rival blowpipe analysis, as regards its rapidity and its unassuming character with regard to space and laboratory appliances, and in many instances surpass blowpipe analysis in the variety and delicacy of its tests. The advantages that accrue from such a method of investigation to chemistry, and all branches of science and industry allied with it, are so great and manifest, that I make boldto call in the co-operation of all those interested in analytical chemistry. It seems to me that the reserved attitude of chemists towards microchemical analysis may have been c...
