The dr^ acid is constituted of 1 proportional of Sulphur ....16.... 40 3 Oxygen 24 60 40 100 Concentrated sulphuric acid boils at about 570°, and freezes at —15°. The dilute acid, of the specific gravity 1.780 freezes at 45°, and when of the specific gravity 1.790, at 32°. The medical uses of this acid will be found under the head of “ diluted sulphuric acid,” in the second part of this work. In consequence of the domestic uses to which the concentrated acid is sometimes applied, cases are not very uncommon in which it has been swallowed by mistake, and in many of which it has proved fatal. The best antidote is a copious draught of chalk and water, or what is better, where it can be speedily procured, of magnesia and water. Instances have occurred, in which the concentrated acid has remained for some hours in the stomach, and has been ejected by vomit- ing ; the patient having afterwards recovered. In these cases a very copious secretion of viscid mucus appears to have de- fended the parts from the immediate corrosive action of the acid. ACONITI FOLIA—The Leaves of the Acoiiitum Napel- lus, or Monkshood, so called from the form of its flowers. This hardy perennial herbaceous plant is abundantly cultivated as an ornament to our gardens and shrubberies. About July it bears a spike of blue flowers. The leaves have little taste till long chewed, when they are acrid, and somewhat bitter, producing a tingling sensation upon the tongue, followed by some tumefaction, and greatly impairing the power of taste for some hours aftenvards. The only preparation of aconite employed in physic is the extract or inspissated juice of the leaves, which, in doses be- tween half a grain and five grains, is said to be narcotic and diuretic ; but it is much too uncertain in its effect, and too mischievous in over-doses, to be employed with safety or
