GROWTH IN PARTS 



TABLE 51. 



Shows for the series of body weights of the albino rat by Jackson and Lowrey 

 ('12) the absolute weights of integument, ligamentous skeleton, musculature, 

 viscera and remainder determined by the use of the percentage values given in 

 the preceding table 60 



Ligamentous skeleton. Since the values for the skeleton as 

 given in tables 50 and 51 were obtained by dissection of the soft 

 parts from the bones, it is evident that these determinations for 

 the skeleton, which here corresponds to the 'ligamentous skeleton' 

 would be high as compared with those obtained after the soft 

 parts had been completely removed by maceration thus giving 

 the 'cartilaginous skeleton' hi the strict sense. 



In view of this difference we have made recently a series of 

 determinations of the relative weight of the cartilaginous skeleton 

 after maceration, Conrow (MS '15). Using these determinations 

 as a basis, table 52 has been formed which gives the values thus
