We may add that, in consequence of these different practices in the two languages, it is a common habit of the German reader to impose a scientific definiteness upon a common word, such as our Fifth Aphorism requires; whereas the English reader expects rather that a word which is to have a technical sense shall be derived from the learned languages. _Die Kelch_ and _die Blume_ (the cup and the flower) easily assume the technical meaning of _calyx_ and _corolla_; _die Griffel_ (the pencil) becomes _the pistil_; and a name is easily found for the _pollen_, the _anthers_, and the _stamens_, by calling them the dust, the dust-cases, and the dust-threads (_der Staub_, _die Staub-beutel_, or _Staub-fächer_, and _die Staub-fäden_), This was formerly done in English to a greater extent than is now possible without confusion and pedantry. Thus, in Grew's book on the _Anatomy of Plants_, the calyx is called the _impalement_, and the sepals the _impalers_; the petals are called the _leaves of the flower_; the stamens with their anthers are the _seminiform attire_. But the English language, as to such matters, is now less flexible than it was; partly in consequence of its having adopted the Linnæan terminology almost entire, without any endeavour to naturalize it. Any attempt at idiomatic description would interfere with the scientific language now generally received in this country. In Germany, on the other hand, those who first wrote upon science in their own language imitated the Latin words which they found in foreign writers, instead of transferring new roots into their own language. Thus the _Numerator_ and _Denominator_ of a fraction they call the _Namer_ and the _Counter_ (_Nenner_ and _Zähler_). This course they pursued even where the expression was erroneous. Thus that portion of the intestines which ancient anatomists called _Duodenum_, because they falsely estimated its length at twelve inches, the {322} Germans also term _Zwölffingerdarm_ (twelve-inch-gut), though this intestine in a whale is twenty feet long, and in a frog not above twenty lines. As another example of this process in German, we may take the word _Muttersackbauchblatte_, the _uterine peritonæum_.
