EXTENDED TO DENSE BODIES. 585 



Similarly condensed oxygen would therefore be only about 6. The molecule of 

 ozone appears to be the dodecatom and icosatom one = 632 = 4 vols. 



Fluorine, 19 ; Chlorine, 35'5 ; Bromine, 80 ; Iodine, 127. 



Our theory of molecular structures is here at war with current atomic weights. 

 In our theory every atomic weight consists of five times as many units of weight 

 as there are units of number in the hydrogen scale ; and the elements of the same 

 substance from different regions of nature, and probably after different manipu- 

 lations in the arts, are apt to vary somewhat in the number of units of weight of 

 which they consist, their full weights being generally somewhat heavier than 

 those most recently adopted in chemistry. Thus the full weight of CI is believed 

 to be = 36, and of 1, = 128. But that by the way. This difference tells but very 

 slightly on specific gravities.

If the experimental determination in the case of iodine be correct, it indicates 

 that some of the molecules are differentiated. (See type (y), p. 583.) 



Phosphorus, 31 ; Arsenic, 75 ', Antimony, 120. 



We may here take phosphorus last, in order to follow it by carbon, with 

 which it has many both physical and physiological relations.

It may be shown that when both an icosatom, either single, such as X^^, or 

 with poles, as X^.^, forms from the same element, such as P or C, which element 

 also forms dodecatoms, then the icosatom is much more open (as for instance to 

 the attacks of oxygen, and therefore far more combustible) than the dodecatom. 

 Hence, with regard to

* The dodecatom and icosatom, when both are differentiated, that is X-XjgX, X X2qX = 36X 

 (the number of elements in AQ), gives, when divided by 2AQ, the same specific gravity as the com- 

 pound dodecatom (X^2)i2— ^ ^ ^^^ when divided by 8AQ.
