i The sum of "undissolved residue" plus "solids extracted" is equal to the moisture-free substance 
In the original product extracted. 
* The figures representing the content of protein, sugars, and acidity in the " solids extracted " were 
obtained from results of actual determinations made on the water extracts, by calculating to a moisture- 
free basis. 
Table 10 gives the results of analysis, both those determined in 
the present investigation and those reported in the literature, for 
whole mesquite beans.
