CORRECTIONS 171 



To transform any determination for the male into that for 

 the female, the value for the male at a given age (see formulas 

 (40) (41), (42) ) is modified by a plus correction (Hatai). 



Correction (plus) = 0.0555 log (age +3) -0.0606 (42a) 

 [10<^e<365] 



The foregoing (40)-(42a) replace the formulas given in the 

 paper by Donaldson ('10). 



Formulas (40) (41) (42) (42a) were used for table 74. 



Percentage of Water in Spinal Cord — (Hatai MS '14) 



The formulas do not apply under 10 days of age. The data 

 for the first ten days are from direct observations. 



Percentage of water in spinal cord — male = 



87.976-0.494 Age +0.00364 Age 2 (Phase 1) (43) 

 [10<^e<40] 



= 100.3 +0.0548 Age - 17.7 log Age (Phase 2) (44) 

 [40 < Age < 150] 



- 62.186 -0.0121 Age +4.434 log Age (Phase 3) (45) 

 [150<A^e<365] 



To obtain from the values for the male at different ages the 

 corresponding value for the female, several corrections are re- 

 quired and these differ according to age. 



From ten to fifty days the following correction formula (45a) is 

 used: 



Correction (minus) = 0.0006 Age 2 - 0.036 Age +0.3 (45a)
