GKOWTH IN WATER AND SOLIDS 



No attempt is made to harmonize in detail these two series 

 of values but the correction coefficients for reducing the observed 

 values in the macerated cartilaginous skeleton to the true values 

 are given in table 127. 



Chart 51 Percentage of water in the entire skeleton oven dried on age 

 and on body weight (albino rat). Table 160. 

 Age. X Body weight. 



Chart 52 Percentage of water in the oven-dried cranium and in the verte- 

 brae, on body weight (albino rat). Table 161. 

 Cranium. X Vertebrae. 



Examination of the tables giving the percentages of water 

 in the different bones shows considerable differences especially 

 after the early stages. These differences appear to be related 

 to differences in the density of the osseous tissue and to the 

 presence of cavities, as in the humerus and femur.
