Excerpt from Micro-Chemistry of Poisons, Including Their Physiological, Pathological, and Legal Relations: Adapted to the Use of the Medical Jurist, Physician, and General Chemist Heretofore the microscope has received but little attention as an aid to chemical investigations, yet it is destined to very greatly extend our knowledge in this department of study. As an evidence of the value of micro-chemical analysis, as the Germans first styled it, it is only necessary to state that it enables us by a very few minutes labor to recognise with unerring certainty the reaction of the 100,000th part of a grain of either hydrocyanic acid, mercury, or of arsenic. Many instances might also be cited in which it, with equal facility, enables us to detect the presence of very minute quantities of substances, the true nature of which heretofore could only be determined when present in comparatively large quantity, and by considerable labor.
