SERIEvS V. 



Series V. is similar to Series II. except that the bone has been re- 

 placed bv its equivalent in rock phosphate. Tlie greatest action is shown 

 by germ Ko. G giving 0.42% soluble PoO-, as against 0.82% by germ 

 !No. 8 in the corresponding bone series. 



Not onl.y is the amount of soluble phosphoric less here than in the 

 bone series but the number of germs which show the solvent action is 

 also fewer. The detailed analvses are given in Table No. 8.
