fremd_ sind, _und nur aus der Natur der Gegenstände in einigen Fällen als Nebengedanken hinzutreten_."[3] [Footnote 3: "To _pack itself_, or to _be packed_, round the axis: that is, upon the axis from all sides. We must not be misled by the present tense: for the forces, which compose and hold together the structure of the universe, are conceived as continuously in active operation. The Earth _packs itself_, or _is packed_, on to the axis--_makes or forms a ball round the axis:_ which corresponds fully to that other usage of the word, in the sense of _wrapping up_ or _swathing round_. Here too there is a superadded something blended with the idea, which conducts us to _turning_, _winding_, and thus to _revolving_: but this is every where nothing more than an accessory notion, suggested by the circumstances of the case. The word has only the meaning, to _pack_, to _fasten_--the senses, to _wind_, to _revolve_, are altogether foreign to it, and can only be superadded as accessory ideas, in certain particular instances, by the special nature of the case."] In these last words Buttmann has exactly distinguished the true, constant, and essential meaning of the word, from the casual accessories which become conjoined with it by the special circumstances of some peculiar cases. The constant and true meaning of the word is, _being packed or fastened close round_, _squeezing or grasping around_. The idea of _rotating_ or _revolving_ is quite foreign to this meaning, but may nevertheless become conjoined with it, in certain particular cases, by accidental circumstances.
