Walter Charleton (1620 - 1707) e sua Teoria At?mica
Porto, Paulo Alves;
Química Nova , 1997, DOI: 10.1590/S0100-40421997000300016
Abstract: several authors in the 17th century used the atomic hypothesis to explain observable phenomena. this paper analyzes some ideas about chemical transformation proposed by the english physician walter charleton. in physiologia epicuro-gassendo-charltoniana (london, 1654), charleton examined philosophical aspects of the atomic theory, and suggested that the best explanation for all natural phenomena would be only in terms of atoms and their motions. sometimes, however, he had to attribute to the atoms some kind of "internal virtue", to explain more complex properties of the matter. his idea of "element", and the little use of experimentation and quantification, also limited the range of charleton's theory.
Os primeiros desenvolvimentos do conceito helmontiano de gás: parte II
Porto, Paulo Alves;
Química Nova , 2003, DOI: 10.1590/S0100-40422003000100025
Abstract: this paper focuses on the early interpretations of the concept of gas, originally created by j. b. van helmont (1579 ? 1644). our main interest is on the ideas of english physicians and chemical philosophers of the seventeenth century. gas was usually associated with the material cause of diseases, with the vital spirit, or with a volatile spirit produced in some kinds of material transformations. as a general trend, however, the authors who did not want to embrace the details of the medico-chemical system proposed by van helmont preferred to use more well-known words (such as vapours, exhalations, effluvia, odours, spirits), avoiding the use of the neologism.
Os três princípios e as doen?as: a vis?o de dois filósofos químicos
Porto, Paulo Alves;
Química Nova , 1997, DOI: 10.1590/S0100-40421997000500021
Abstract: paracelsus (1493 - 1541) developed a theory about three principles (sulphur, mercury, and salt) that would constitute matter, and whose mutual interactions within man's body could cause diseases. this paper discusses the influence of this theory on the work of two chemical philosophers. oswald crollius (1560 - 1609) considered that the conceptions of matter and disease were strongly related because of the macro - microcosm analogy, and classified diseases in sulphurean, mercurial and saline. on the other hand, j. b. van helmont (1579 - 1644) stated that sulphur, mercury, and salt were not true principles, and that every disease would have a specific origin. instead of the principles, van helmont put the archeus at the center of both his medical and matter theories.
O médico George Thomson e os primeiros desenvolvimentos do conceito de gás
Porto, Paulo Alves;
Química Nova , 2001, DOI: 10.1590/S0100-40422001000200021
Abstract: the word gas was coined by the "chemical philosopher" joan baptista van helmont (1579 ? 1644) to name a very broad concept in his chemico-medical system. eventually, some physicians who followed helmontian ideas adopted the concept. the present paper aims to analyze the reception of the original idea of gas by an english helmontian physician, george thomson (1619 ? 1677). thomson wrote that the "material cause" of the plague was a gas, and compared it to the "gas of sulphur". he also related the human archeus to a gas, and explained some observations in the laboratory in terms of production of gases. we observe, however, that thomson was not as interested as van helmont in discussing details about the structure of the matter. thus, gas did not have the same relevance in thomson's work as it had in van helmont's.

Eventually, some physicians who followed Helmontian ideas adopted the concept. The present paper aims to analyze the reception of the original idea of gas by an English Helmontian physician, George Thomson (1619 -- 1677). Thomson wrote that the "material cause" of the plague was a gas, and compared it to the "Gas of sulphur". He also related the human archeus to a gas, and explained some observations in the laboratory in terms of production of gases. We observe, however, that Thomson was not as interested as Van Helmont in discussing details about the structure of the matter. Thus, gas did not have the same relevance in Thomson's work as it had in Van Helmont's.

Abstract: This paper focuses on the early interpretations of the concept of gas, originally created by J. B. Van Helmont (1579 fraction three-quarters 1644). Our main interest is on the ideas of English physicians and chemical philosophers of the seventeenth century. Gas was usually associated with the material cause of diseases, with the vital spirit, or with a volatile spirit produced in some kinds of material transformations. As a general trend, however, the authors who did not want to embrace the details of the medico-chemical system proposed by Van Helmont preferred to use more well-known words (such as vapours, exhalations, effluvia, odours, spirits), avoiding the use of the neologism.
