In their chapter one, as to the human being, they state that “from the information on the quantities of individual elements, we can calculate the stoichiometric formula for a living human being to be”, taking cobalt (Co) as unity: 
H375,000,000 O132,000,000 C85,700,000 N6,430,000 Ca1,500,000 P1,020,000 S206,000 Na183,000 K177,000
Cl127,000 Mg40,000 Si38,600 Fe2,680 Zn2,110 Cu76 I14 Mn13 F13 Cr7 Se4 Mo3 Co1
This amounts to a 22-element human empirical molecular formula. They concludes “this formula combines all compounds in a human being into a single abstract ‘molecule’”. They continue, “our main purpose in introducing this formula for the ‘human molecule’ is to stimulate you to begin to think about how every human being represents the coming together of atoms in proportions that are, if not constant, at least bounded and obeying some rules”.
