Table 7 shows the contribution of each important source 
language to the entire 10,000 English words in Professor 
Thorndike's Teacher’s Word Book, 
The plan of Table 7 is the same as that of Table 5. 
Tables 5, 6, and 7 should be compared. 
Table 8 shows the relation of the Latin source words 
contributing to the English words in Professor Thorndike's 
Teacher’s Word Book with the Latin words in Professor 
Lodge's Vocabulary of High School Latin, 
The table showing the relation of the Lodge Latin list to 
the list of the source words of the Latin derivatives among 
the 10,000 English words in the Teacher’s Word Book is to 
be interpreted as follows: The figure 1,110 at the bottom of 
the first column expresses the number of Latin source words 
from which come the Latin derivatives in the Teacher’s Word 
Book, Now reading the first line across the top of the table, 
we are to understand that 290 out of the 1,110 source words 
mentioned above are to be found among the Latin words in 
the Caesar list of Lodge's Vocabulary of High School Latin. 
It should be noted that more of the 1,000 words in Lodge's 
Caesar list than the 290 just mentioned are really related to 
the source words in our list because Lodge includes ‘"de-cipio", 
“incipio", re-cipio", etc., as well as the simple form “capio", 
while in our list compound forms are usually not separately 
noted, but all derivatives of the “capio" family, for example, 
are traced back to the simple form “capio". Continuing our 
reading, the 290 words common to Lodge's Ceasar list com- 
prise 26.13 per cent of the total of 1,110 Latin source words 
in our list. These 290 Latin words have 1,911 English de- 
rivatives among the words in Thorndike's Teacher’s Word. 
Book. These derivatives comprise 43.98 per cent of all the 
Latin derivatives in the Teacher’s Word Book. The sum of 
the frequency index numbers of ail the English words in 
Thorndike's Teacher’s Word Book that are derived from these 
290 Latin words is 30,857, and this sum is 46.54 per cent of 
the total sum of all the frequency index numbers of all the 
words in the Teacher’s Word Book that are derived from 
Latin. 
The figures in the row following the word “Lodge" are the 
statistics on those words in our list that are included in 
Lodge's Vocabulary of High School Latin but are not in his
