* No. 476. Calcium oxide guaranteed 30.00%, found 29.13%. There was also 1.04% magnesium oxide present. 

 12.29% of the lime was apparently present in combination with the phosphoric acid, so that not more than 17.88% of 

 calcium and magnesium oxides were present in forms similar to agricultural lime.
