consequently the empty spaces serve as a resistence to the ac 

 tion of the force of centrality and a resistance to the motion. 

 Therefore a different porosity brings a different resistance in 

 motion and a different motion is a different quality in the body. 

 The law of Avogadro, which is generalized as follows, The 

 molecules of all gases, simple or compound, occupy equal vol 

 umes, or, equal volumes of all gases contain equal numbers of 

 molecules&quot;, can be accepted, according to the above six laws, 

 only the first part of it, that the molecules of all gases occupy 

 equal volumes, that a molecule of oxygen occupies the same 

 volume as a molecule of hydrogen, the difference between them 

 is only the different porosities, which is the different density, 

 but not according to the atomic theory of our chemists, that the 

 atoms themselves are the elements, and accordingly the volume 

 of an atom oxygen must be 16 times larger than that of hydro 

 gen. The second part of the law of Avogadro, that equal vol 

 umes of all gases contain equal numbers of molecules is utterly 

 false. Two glasses of equal dimensions, the one filled with 

 oxygen and the other with hydrogen, by equal pressure and 

 equal temperature, must be the number of the molecules in the 

 glass of oxygen so many times larger than the hydrogen, as the 

 density of the oxygen is larger than the density of hydrogen, or 

 as the porosity of oxygen is smaller than that of hydrogen. The 

 experiments of the most brilliant chemists of the century, as 

 Barzelius, Dialong, etc., and of the latest one F. H. Keizer, on 

 the atomic weight of oxygen compared with hydrogen, as 16, 

 is not an evidence to their result, that an atom of oxygen com 

 pared with hydrogen is 16, but that a molecule of oxygen 

 compared with hydrogen is 8. Those experiments are deter 

 mined as follows: Pure dry hydrogen gas was passed over a 

 red hot copper oxide, combining with the oxygen of the latter 

 it formed 30.519 G. water. The copper oxide lost 27.129 G. of 

 its weight and this figure represents the weight of oxygen in the 

 above weight of wate r ; which contains thus, 3,0.519^27.129=3.390 

 G. of hydrogen. In the same way an experiment was made by 

 Keizer. Now, instead of this to calculate this experiment plain 

 ly, that as in 30.519 G. water was found 27.129 G. of O. and
