of the order cannot readily be explained, the principal laws which 

 govern its morphology, and which have been noted in previous 

 papers, are sufficiently evident. These are, that the development

 related with the energy of the masticatory power, joined in some 

 of the higher apes with a prehensile strength of jaws and dental 

 series eminently characteristic of their ferocity.

The phosphates of the system 

 are consumed with every effort, 

 and exhaustion usually indicates 

 a lack of supply. The Acid 

 Phosphate supplies the phos- 

 phates, thereby relieving exhaus- 

 tion, and increasing the capacity 

 for labor. Pleasant to the taste.
