Présentation de l'éditeur :
In Physics, Chemistry and Mineralogy the properties of the objects are measured and expressed by means of figures called constants. A constant is independent of any theory: it is the exact expression of a fact. The constants are in reality the material by means of which theories are built up, the explanation of the observed facts is found and the road opened for new discoveries. In Botany and Zoology, on the contrary, the properties (characters) of the living things are usually described by means of terms. We say that a given object is long or short, broad or narrow, oblong or oval, etc. Much progress would be rendered possible if such terms as long, broad, short, etc., were replaced by figures. This would be simple enough if the properties of animals and plants were invariable. Unfortunately these properties are almost always variable, not only within the limits of one species, but also among the children of the same parents and even among the progeny of one parent. Variability has been hitherto the great obstacle which has rendered impossible the general use of quantitative data (figures) in Biological Sciences. The object of the present book is to describe a method by which biological constants may be established. In the first two chapters I have expounded certain theoretical views about the notion of species and variation. Those views afford us a guide for the discovery of the primordia (simple or elementary properties or characters) which are to be measured in order to find constants. The constants themselves are, however, entirely independent of any theory and of any Parthenogenesis, apogamy, asexual multiplication in animals and plants.
