What counted as the most significant chemical components or principles of plants changed considerably around 1750. Whereas by 1700 chemists were almost exclusively concerned with the ultimate simple elements or principles of plants—apart from a few individual exceptions, such as Simon Boulduc—, after 1750 the majority of chemists became more interested in the compound components or proximate principles of plants. The increase in collective attention the compound components of plants received from 1750 on did not entirely replace the search for the ultimate principles of plants. Instead, chemists began to establish an order of analysis by distinguishing between two kinds of plant-chemical analysis first, the analysis of entire plants and the organized parts of plants, which aimed at separating the more compound or proximate principles of plants and, second, the further analysis of the proximate principles into their ultimate components or simple principles. Whereas the lat-... 

Homberg s quantitative experiments on the neutralisation of acids and bases are the first determinations of equivalent weights. Simon Boulduc (d. Paris, 1729 demonstrator in the Jardin du Roi) tried in 1698 to find the...
