(a) Percentage of water in the cartilaginous skeleton and its

 tables 160-163 and in charts 51-54. 



The observations of Lowrey, just cited, give the percentage

TABLE 159 



Percentages of water in the entire body in several of the systems and in some organs. 

 Observations at seven ages. See Chart 50. 



* "All viscera" comprises the series of organs used by Jackson and Lowrey ('12). See note 9, pone 264
