Experiments on the Distillation of Acids, volatile Alkalies, &c. showing how they may be condensed without Loss

Descripción

Safety is a common denominator in all laboratory work, and this scientific paper clearly states the problem to be solved in the first paragraph. The author states "In the common matter of distillation there escapes a great quantity of fumes, which cannot be condensed; and in several operations these fumes are very hurtful to the lungs. By the following method of distillation these fumes are totally condensed, which makes a great saving in some distillations, and the operator is in no danger of being hurt by any pernicious vapours.The paper is titled "Experiments on the Distillation of Acids, volatile Alkalies, &c. showing how they may be condensed without Loss, and how thereby we may avoid disagreeable and noxious Fumes: In a Letter from Mr. Peter Woulfe, F. R. S. to John Ellis, Esq, F. R. S.". The item is a First Edition, extracted and disbound from The Philosophical Transactions of the Royal Society, Vol. 57, Part II For the Year 1767, pages 517-536, with two accompanying fold-out plates that contain 6 Figures. This volume of the transactions was published in London in 1768. The disbound item measures approximately 6 1/4 x 8 1/2 inches. Its pages are tanned, but the text and figures are clear and easily read. The overall condition of the paper, considering its age and being extracted from its original covers, is good. The illustrations accompanying this description show the first page of the document and the two fold-out plates with their drawings of the apparatuses used in the experiments. Peter Woulfe (1727 - 1803) was an Irish chemist and mineralogist. He first had the idea that wolframite might contain a previously undiscovered element (tungsten). In 1779, Woulfe reported the formation of a yellow dye when indigo was treated with nitric acid. Later it was discovered by others that he had formed picric acid, which eventually was used as the first synthetic dye, an explosive and an antiseptic treatment for burns. Woulfe is credited with inventing the Woulfe Bottle, a kind of wash bottle with two or three necks. [Wikipedia] John Ellis FRS (1710 - 15 October 1776) was a British linen merchant and naturalist. Ellis specialized in the study of corals. He was elected a member of the Royal Society in 1754 and in the following year published "An essay towards the Natural History of the Corallines". Ellis was appointed Royal Agent for West Florida in 1764 and for Dominica in 1770. He imported many seeds and plants into England from America, and corresponded with many botanists, including Carolus Linnaeus. [Wikipedia]. N° de ref. del artículo 001620
