Although Macquer s explanation is correct, A.-L. Lavoisier still held to the more conservative opinion. In his Elementary Treatise on Chemistry, which was first published in 1789, he explained the formation of potassium carbonate in vegetable ash as follows As the potash is not formed, or at least not liberated, said he, except as the carbon of the plant is converted into carbonic acid by the addition of oxygen, either from the air or from the water, the result is that each molecule of potash, at the moment of its formation, finds itself in contact with a molecule of carbonic acid, and since there is great affinity between these two substances, combination must take place (13).

Concerning affinity, Lavoisier s evaluation contrasted sharply with his condemnation of the doctrine of chemical principles. Far from regarding it as a dead subject, he appreciated the intensifying interest in affinity as the theoretical frontier of chemistry. It was precisely for this reason that he decided to exclude it from the Traite. The subject of affinity lacked a solid foundation on facts and did not belong to an elementary treatise ... 

In the case of book titles, a reasonably complete form has been given, such words as An Elementary Treatise on. . being often omitted. The place of publication has usually been given, but if the title is English and no place is specified, London is to be understood, and if in French, Paris. A full list of journal abbreviations is given below. Some references contain bibliographies, and this has mostly been noted.

Manquat s Elementary Treatise on Therapeutics (1903) describes the heroic experiments of colleagues who tested, on their own persons, the effects of medication taken in ever-increasing doses until convulsions ensued (ingestion of 10 g of resorcinol in 15 minutes). The indications officially retained in 1903 were the following ... 

Lavoisier formulated the rule that chemical reactions do not alter total mass after finding that reactions in a closed container do not change weight. This disproved the phlogiston theory, and he named Priestley s substance oxygen. He demonstrated that air and water were not elements. He defined an element as a substance that could not be broken down further. He published the first modern chemistry textbook. Elementary Treatise of Chemistry. Lavoisier was executed in the Reign of Terror at the height of the French Revolution.

It is perhaps necessary to add a few more remarks so as to give the beginner an inkling of the vastness of the subject we are about to leave behind. P. Frost s An Elementary Treatise on Curve Tracing, London, 1872, is the text-book on this subject. Before you proceed to the actual plotting, look out for symmetrical axes maxima and minima ordinates points of inflexion and asymptotes. Does the curve cut the axes at any points There may be other singular points besides points of inflexion, and maxima and minima.

An adequate discussion of the conditions of convergency of Fourier s series must be omitted. W. E. Byerly s An Elementary Treatise on Fourier s Series, etc., is one of the best practical works on the use of Fourier s integrals in mathematical physics. J. Fourier s pioneer work Thiorie analytiquc de la Chaleur, Paris, 1822, is perhaps as modern as any other work on this subject see also W. Williams, Phil. Mag. [5], 42, i25,1896 Lord Kelvin s Collected Papers and Riemann-Weber s work (Z.c.), etc. 

Lavoisier s quantitative experiments showed that combustion involved oxygen (which Lavoisier named), not phlogiston. He also discovered that life was supported by a process that also involved oxygen and was similar in many ways to combustion. In 1789 Lavoisier published the first modern chemistry textbook. Elementary Treatise on Chemistry, in which he presented a unified picture of the chemical knowledge assembled up to that time. Unfortunately, in the same year the text was published, the French Revolution broke out.

Finally, in 1787, Lavoisier together with the French chemists, de Morveau, Ber-thollet and de Fourcroy established in Paris a new chemical nomenclature, that has remained valid until today. Lavoisier wrote in 1789 the Trade elementaire de Chimie (Elementary Treatise of Chemistry), the first modem textbook on chemistry, and presented a unified view of new theories of chemistry, containing a clear statement of the law of conservation of mass, and denied the existence of phlogiston. In addition, it contained a list of elements, or substances that could not be broken down further, which included oxygen, nitrogen, hydrogen, phosphoms, mercury, zinc, and sulfur. 

The first definition of the chemical element, in the modem sense, is due to R. Boyle (1627-1629) in his book Skeptical Chemist, he defined the chemical element as a substance which cannot be decomposed into other substances. So, the elements (simple bodies) are not composed of other substances, but they themselves are the products in which are decomposed, ultimately, all other substances. Boyle did not shown specifically what these items were about, for example, he could not decide if metals or their oxides had a character of an element. On the other hand, the negation, which stay on the basis of his statement, make it uncertain as a practical definition, because even not known the decomposition methods for a substance at a given time (historical epoch), this not necessarily means that such a decomposition is not possible in an arguable future. In any case, the use of the term element, in the sense of elemental substance, i. e., simple substance, was maintained until now, with the note that only its significance was made clear as time passed by. An important step was the transition from the meaning of the element notion as principle, encompassing a collection of properties, to some specific to substance type. Noteworthy, Lavoisier, in his famous Elementary Treatise of Chemistry (1789) included in the simple substances category approximate 40 substances, of which 25 were really elements (Horovitz et al., 2000). 

The foundation of chemistry was constructed by A. de Lavoisier, the father of modern chemistry. Lavoisier proposed the law of the conservation of mass stating the mass of an isolated system is maintained as a result of processes acting inside the system, and organized the whole knowledge of earlier chemistry in his book, Traite elementaire de chimie (Elementary Treatise on Chemistry) (1789). Following the law of definite composition (1799) stating a chemical compound always contains exactly the same proportion of elements by mass, suggested by...
