80 HENRY H. DONALDSON 
TABLE 1 
Giving for the percentage of water in the brain the data used for the making of table 
74 (Donaldson ’15), which is appended to this article. The records are entered 
by age groups, male and female records being given separately. For any age 
group of either sex the table gives the age to a day—or within a range of five days, 
followed by the number of cases—and then by the percentage of water. This datum 
appears first, as observed, second, as corrected for the brain weight and third, as 
given in table 74, where the values have been computed by formulas (Hatai), these 
formulas, in iurn, being based on the corrected values as here entered. When the 
age is given within a range of five days the interval 5-10 is taken as 8, and 0-5 as 
8; 7.e., 25—380 = 28 days, 30—35 = 33 days
