Publisher's Synopsis
Excerpt from The Elements of Pharmacy, and of the Chemical History of the Materia Medica
With this view, the means of research are first considered generally as the structure and use of the thermometer, the balance, and the weights and measures, now used in this country; respecting which, there is given a historical ac count of the introduction of the' several species of weights and measures into this country, and tables, not only of the Roman weights, still used by Latin writers, but also of those of the Saxons and Danes, from whom some of our weights are derived. Nor are the French, German, and Swedish weights and measures, often mentioned in chemical works translated from those languages, left unnoticed. This is succeeded by an account of the different methods of ascertaining the density, or specific gravity of substances; and the mode of operating upon the various species of air, or what are now more usually called by their Flemish name of gas introduced into che mistry by Van Helmont.
